When you self-calibrate your AO Series device, no signal connections are necessary. However, values generated on the analog output channels change during the calibration process.
When externally calibrating your AO Series device, connect the signals as described below for the type of AO Series device you are calibrating. Set the reference voltage between +6.000 V and +9.999 V. Typically, you use a calibrator or other stable voltage source for the reference voltage. Do not use a power supply as its signals are not very stable.
Follow these steps for AO Series devices:
