The Laureate™ 1/8 DIN Digital Panel Meter, Ohmmeter for resistance in Ohms

is ideal for high-speed, high-accuracy resistance measurements in a production environment, such as contact resistance measurements. It is factory calibrated for five jumper selectable resistance ranges from 20.000 ohm to 200.00 kohm. Fixed, factory-special ranges of 2.0000 ohm, 2.0000 Mohm and 20.000 Mohm are also available. Accuracy is an exceptional ±0.01% of reading ± 2 counts. Resolution is one part in 20,000. In the 2 ohm range, resolution is 0.1 milliohm, making the digital panel meter suitable for contact resistance measurements.

The optional extended Laureate computer board enhances the Laureate Digital Panel Meter by displaying rates derived from successive readings and enabling highly accurate custom curve linearization. For example, it can calculate liquid volume or flow rate in a horizontal cylindrical tank using levels from a 4-20 mA transmitter. Setup is straightforward: users input up to 180 data points into a spreadsheet or text file, and the computer calculates spline-fit segments, which are then downloaded to the digital panel meter for precise operation.

Digital Panel meter connections can be via 2, 3 or 4 wires. With 4-wire hookup, 2 wires are used for excitation and two separate wires are used to sense the voltage across the resistance to be measured, thereby eliminating any lead resistance effects. With 3-wire hookup, the digital panel meter senses the combined voltage drop across the resistance to be measured plus two excitation leads. It also senses the voltage drop across one excitation lead, and then subtracts twice this voltage from the combined total. This technique effectively subtracts lead resistance if the excitation leads are the same.

All resistance ranges are factory-calibrated, with calibration factors for each range securely stored in an onboard EEPROM. These factors can be scaled via software to accommodate external shunts, enabling field replacement of signal conditioner boards without necessitating recalibration of the associated digital panel meter. For optimal accuracy, factory recalibration is recommended annually. All Laurel Electronics instruments undergo factory calibration using the industry-leading Fluke calibrators, which are recalibrated yearly and certified traceable to national standards, ensuring the highest level of precision and reliability.

The Laureate Digital Panel Meter is easily programmed with Laurel’s free Instrument Setup Software, downloadable from our website and compatible with Windows PCs, requiring a data interface board for setup.

High read rate of up to 50 or 60 conversions per second, the Laureate™ Digital Panel Meter uses Concurrent Slope (US Pat. 5,262,780) analog-to-digital conversion to integrate signals over a full power line cycle (50 Hz or 60 Hz). This read rate enables peak and valley capture, real-time computer interfacing, and control applications. Peak and valley values are automatically captured and can be viewed using Laurel’s free Instrument Setup Software (compatible with Windows PCs) or transmitted as serial data.

Digital signal filtering modes can be selected to ensure stable readings in electrically noisy environments.

An unfiltered selection provides true peak and valley readings and aids in control applications.
A batch average filter selection averages each 16 conversions.
An adaptive moving average filter selection provides a choice of 8 time constants from 80 ms to 9.6 seconds. When a significant change in signal level occurs, the filter adapts by briefly switching to the shortest time to follow the change, then reverts back to its selected time constant. An Auto setting selects the time constant selection based on signal noise.

Two tare functions: auto-tare and manual tare. In auto-tare, an input line is grounded by an external pushbutton. This causes the current weight, which is normally the empty weight of the container to be stored in memory as an offset. In manual tare, the tare value can be entered manually via the front panel or a computer using Laurel's free Instrument Setup Software. For instance, the tare value may be the stated empty weight of a truck or rail car. Pressing the Reset button on the front panel toggles the display between gross weight (total weight on the scale) and net weight (gross weight with tare subtracted).

Peak and valley values are automatically captured. These may be displayed via a front panel pushbutton command or control signal at the rear connector, or be transmitted as serial data.

Two rear panel control Inputs (CMOS/TTL levels, logic 0 = tied to digital ground, logic 1 = open) or dry contacts that can be set to control / activate 14 meter commands.

Resistance Measurement with Excitation & Lead Compensation

Ohmmeter hookup can be via 2, 3 or 4 wires to the J5 connector. The digital panel meter applies a fixed excitation current for each resistance range.
	In 4-wire hookup, different pairs of leads are used to apply the excitation current and sense the voltage drop across the unknown resistance, so that the IR drop across the excitation leads is not a factor.
	In 3-wire hookup, the digital panel meter senses the combined voltage drop across the unknown resistance plus two excitation leads. It also senses the voltage drop across one excitation lead, and then subtracts twice this voltage from the combined total. This technique effectively subtracts all lead resistance and compensates for ambient temperature changes if the two excitation leads are identical.
	In 2-wire hookup, the digital panel meter senses the combined voltage drop across the unknown resistance and both lead wires. The voltage drop across the lead wires can be measured by shorting out the resistance during meter setup, and this voltage is then automatically subtracted from the combined total. However, changing resistance of the lead wires due to ambient temperature changes will not be compensated.

QA Application with Relay Option in Passband Mode

Deviation mode relay operation for digital panel meters and counters

A deviation limit (50 mohm in this example) is set up around both sides of a setpoint. The relay closes (or opens) when the reading falls within the deviation band, and opens (or closes) when the reading falls outside of this band. This mode sets up a passband around the setpoint and can be used for contact resistance testing.

Panel Mounting

Mechanical Panel Mounting Guide Slide the meter into a 45 x 92 mm 1/8 DIN panel cutout. Ensure that the provided gasket is in place between the front of the panel and the back of the meter bezel. The meter is secured by two pawls, each held by a screw, as illustrated. Turning each screw counterclockwise extends the pawl outward from the case and behind the panel. Turning each screw clockwise further tightens it against the panel to secure the meter.

Turning each screw counterclockwise loosens the pawl and retracts it into its well. This position allows installed meter to be removed from their panel, or new meters to be installed in a panel. Do not remove the screws from their pawls. Doing so would cause the screw and pawl to fall off and likely get lost. Do not overtighten so as not to damage the plastic parts.

What is a Digital Panel Meter Ohmmeter for Resistance in Ohms?

A Digital Panel Meter ohmmeter is a precision instrument designed to measure and display electrical resistance in ohms, typically from resistive sensors, circuits, components, or materials. This Digital Panel Meter is vital in industrial, laboratory, quality control, and testing applications where accurate resistance measurements are critical, such as in electronics manufacturing, quality assurance, circuit diagnostics, sensor calibration, and electrical safety testing. By converting resistance signals (from milliohms to megaohms) into clear digital readouts, this Digital Panel Meter ensures reliable data for process monitoring, equipment maintenance, system optimization, and compliance verification.

Unlike traditional analog ohmmeters or handheld multimeters, this Digital Panel Meter ohmmeter offers superior accuracy (±0.05% to ±0.5% typical), continuous monitoring capability, programmable alarm functions, and integration with modern control systems through digital communication. The ability of this Digital Panel Meter to measure a wide range of resistance values, from micro-ohms (µΩ) for contact resistance testing to mega-ohms (MΩ) for insulation resistance testing, makes it versatile for diverse applications, including testing electrical components, monitoring sensor performance, verifying circuit integrity, and detecting insulation degradation.

Understanding the Digital Panel Meter Ohmmeter

This Digital Panel Meter for ohmmeter applications is typically built to the 1/8 DIN standard, fitting compactly into panel cutouts (approximately 92 mm x 45 mm or 96 mm x 48 mm depending on manufacturer). This compact size ensures compatibility with control panels, test benches, production line monitoring stations, or quality control equipment while optimizing space, making it ideal for industrial control rooms, electronics testing laboratories, manufacturing test stations, or equipment panels with limited space.

This Digital Panel Meter is designed to measure resistance by applying a known precision current (constant current method) or voltage to the resistive element and calculating the resulting resistance based on Ohm's Law (R = V/I). It features bright LED (red, green, amber) or backlit LCD displays with 3-5 digit resolution, user-friendly interfaces with front-panel programming, and communication interfaces like RS-232, RS-485, Modbus RTU/TCP, or Ethernet for integration with PLCs, SCADA systems, data acquisition systems, or quality management software. Advanced features of this Digital Panel Meter, such as 2-wire (simple but least accurate), 3-wire (compensates for one lead), or 4-wire Kelvin measurement configurations (highest accuracy, completely eliminates lead resistance errors), ensure high accuracy by compensating for lead wire resistance, making it suitable for precise low-resistance measurements (milliohms) in demanding production or laboratory environments.

How Does a Digital Panel Meter Ohmmeter Work?

This Digital Panel Meter ohmmeter measures resistance in ohms and displays the results accurately. Below is a detailed breakdown of its operation:

Test Current Generation:
This Digital Panel Meter generates a precision test current (typically 1 mA, 10 mA, 100 mA, or 1 A depending on resistance range and accuracy requirements) that is applied to the device under test (DUT). The test current must be highly stable (±0.01%) and accurately known to ensure measurement accuracy. Lower test currents (1-10 mA) are used for high-resistance measurements to avoid self-heating, while higher currents (100 mA-1 A) are used for low-resistance measurements to provide sufficient voltage drop for accurate measurement.
Signal Acquisition:
This Digital Panel Meter applies the controlled test current to the resistive element (e.g., a resistor, motor winding, cable, sensor, contact resistance, or insulation) and measures the resulting voltage drop across the resistance using precision voltage measurement circuitry. For a 4-wire Kelvin connection, separate force (current-carrying) and sense (voltage-measuring) connections eliminate lead wire resistance errors completely.
Lead Resistance Compensation:
For 2-wire configurations (simplest but includes lead resistance in measurement, causing errors especially for low resistances), this Digital Panel Meter measures total resistance including leads. For 3-wire configurations (common in industrial applications), this Digital Panel Meter uses compensation assuming equal lead resistances to cancel lead wire errors, improving accuracy. For 4-wire (Kelvin) configurations (highest accuracy, standard for precision measurements), this Digital Panel Meter uses separate current-carrying and voltage-sensing wires to completely eliminate lead resistance errors, ensuring measurement accuracy is independent of cable length or resistance (critical for milliohm measurements).
Signal Conditioning:
The voltage signal (proportional to resistance) is conditioned through precision instrumentation amplification, digital filtering (programmable time constants) to remove noise from 50/60 Hz power lines or electrical interference, and auto-ranging to select optimal measurement range. This ensures the signal is within the optimal operational range of this Digital Panel Meter and minimizes errors from electrical interference, thermal EMF, or transient voltages.
Analog-to-Digital Conversion:
A high-resolution Analog-to-Digital Converter (ADC), typically 16-bit, 20-bit, or 24-bit sigma-delta type, transforms the conditioned voltage signal into a digital format. High-resolution ADCs (24-bit provides sub-milliohm resolution) are critical for detecting small resistance changes or measuring very low resistances (contact resistance, bond resistance, ground resistance) or very high resistances (insulation resistance, leakage resistance), enabling precise quality control and fault detection.
Resistance Calculation and Processing:
The digital signal is processed by the microcontroller of this Digital Panel Meter, which calculates resistance using Ohm's Law (R = V/I), applies calibration corrections (zero offset, span adjustment), auto-ranging to select appropriate units, and unit conversions (mΩ, Ω, kΩ, MΩ). Advanced models include temperature compensation for resistive elements with known temperature coefficients or normalize readings to standard reference temperature (20°C or 25°C).
Display:
The calculated resistance is displayed on a bright LED (0.56" to 0.8" character height) or backlit LCD screen with 3-5 digits, automatic decimal point positioning, engineering units (µΩ, mΩ, Ω, kΩ, MΩ), and often with bar graph indication or dual-line displays showing both resistance value and pass/fail status for quality control applications.
Output and Integration:
This Digital Panel Meter provides multiple outputs including 4-20 mA or 0-10V analog retransmission signals proportional to resistance for chart recorders or PLCs, relay contacts (typically 2-4 SPDT relays) for programmable alarms (high resistance, low resistance, out-of-tolerance limits) for pass/fail testing or process control, and digital communication protocols (RS-232, RS-485, Modbus RTU, Modbus TCP/IP, Ethernet/IP) for integration with PLCs, SCADA systems, manufacturing execution systems (MES), or quality management databases for statistical process control (SPC) and traceability.
Calibration and Configuration:
Users can calibrate this Digital Panel Meter using precision reference resistors (NIST-traceable standards), configure resistance ranges (auto-range or fixed range), select measurement modes (2-wire, 3-wire, 4-wire), set test current levels, configure alarm thresholds (absolute or percentage limits), select display units, adjust filtering, or set communication parameters to suit specific application requirements for production testing, quality control, or laboratory calibration.
