Calibrating the OMB-DAQ-2416-4AO
The OMB-DAQ-2416-4AO is initially calibrated using an NIST-traceable calibration method. This method
stores a correction factor for each AIN and AOUT range in non-volatile memory on the device at the time of
calibration.
Allow a 45 minute warm-up period before calibrating the OMB-DAQ-2416-4AO.
Calibration methods
Factory calibration
You can return the OMB-DAQ-2416-4AO once a year to Omega Engineering for a new factory calibration and
calibration certificate.
Self calibration
Use InstaCal to calibrate the OMB-DAQ-2416-4AO whenever the ambient temperature changes by more than
±10 °C from the last self-calibration
You can perform this procedure with thermocouple and voltage inputs connected to the input terminal blocks.
To calibrate the AOUT circuits, disconnect the analog outputs at the terminal block pins to ensure optimum
calibration results.
