17. TRANSMITTER CALIBRATION

All input ranges are calibrated at the factory using NIST certified calibration equipment, and

the calibration constants are stored digitally in EEPROM on the signal conditioner board. This

allows signal ranges and signal conditioner boards to be changed in the field without trans-

mitter recalibration. Calibration constants for analog outputs are stored in EEPROM on the main

board.

If recalibration is required, a transmitter may be returned to the factory or to an authorized

distributor. Easy calibration of DC, AC and load cell signal conditioner ranges is also possible

with Instrument Setup software, as described in Section 7. Advanced calibration software is

available from the factory.
