Certificate of Calibration for Laurel Electronics Digital Panel Meters and Transmitters
Laurel Electronics, LLC offers a Certificate of Calibration as an available option for its panel meters and transmitters. This document provides formal documentation that the unit has been tested and calibrated using NIST-traceable standards to meet or exceed all published specifications across its operating ranges. The certificate includes:
- Company header and official certification statement from Laurel Electronics, LLC
- Specific unit identification (model and serial number)
- Detailed list of NIST-traceable calibration equipment used, including model, serial number, calibration date, due date, and traceability reference
- Controlled environmental conditions during testing (temperature 23–27°C, humidity <95% RH)
- Calibration date and authorized signature
Certificate of Calibration for Analog Digital Panel Meters and Transmitters
For analog panel meters (e.g., edgewise, round, or rectangular moving-coil models), the certificate certifies that the meter has been mechanically adjusted and tested across its full scale for pointer accuracy, linearity, damping, and overall performance. It includes verification of mechanical zero adjustment, scale conformity, and response characteristics, along with a detailed list of NIST-traceable calibration equipment used (model, serial number, calibration date, due date, and traceability reference).
Certificate of Calibration for Digital Panel Meter and Transmitter Counters and Timers
For Laureate™ Series digital panel meters and DIN rail transmitters, the certificate certifies multi-point calibration with any correction factors stored in the meter's non-volatile EEPROM memory for enhanced long-term stability. It confirms high precision and reliability (typically ±0.01% of full scale or better), with the same comprehensive details on NIST-traceable equipment and controlled test conditions.
This optional documentation is particularly valuable for regulated industries or applications requiring formal traceability and assurance of measurement integrity.
