AO Waveform Calibration Procedure for NI-DAQmx
Use the AO adjustment procedure to adjust the analog output calibration
constants. At the end of each calibration procedure, these new constants are
stored in the external calibration area of the EEPROM. These values are
password-protected, which prevents the accidental access or modification
of any calibration constants adjusted by the metrology laboratory. The
default password is
NI
To perform adjustment of the device with a calibrator, complete the
following steps:
1. Connect the calibrator to the device according to Table 3.
Table 3. Connecting the Calibrator to the Device
671X/672X/673X Pins
AO EXT REF (pin 20)
AO GND (pin 54)
2. Set your calibrator to output a voltage of 5 V.
3. Open a calibration session on your device using
(DAQmx Initialize External Calibration VI). The default password
is .
NI
