All ranges of Laureate analog signal conditioner boards and analog output boards are factory calibrated, with calibration factors stored in EEPROM on these boards. This allows different ranges to be selected via plug-in jumpers and different boards to be plugged into the meter, with no need to recalibrate the meter as a system. Calibration by Laurel uses CalWin custom software working with programmable Fluke 5500A calibrators. These are calibrated by Fluke annually and are self-calibrated weekly. The list of the equipment used to calibrate a specific Laureate meter or counter and the calibration dates of this equipment are available as an option by ordering a Certificate of Calibration.
Annual calibration of Laureate analog signal conditioner boards can be performed by a customer’s cal lab using an external standard, a PC, and Laurel’s Instrument Setup (IS) Software, which can be downloaded at no charge. For communications, the meter must be equipped with an RS232 board or USB board, and an appropriate PC communication cable. Following calibration, the communication board can be removed and be used to calibrate another Laureate meter. Laureate transmitters come standard with RS232/485 or Ethernet communications, as ordered.
