© National Instruments Corporation 53 NI 4070/4072 Calibration Procedure
9. Reset the calibrator for safety reasons.
10. Call
niDMM_CalAdjustMisc with Type set to
NIDMM_EXTCAL_MISCCAL_SECTION.
You have completed adjusting the AC voltage modes of the NI 4070/4072.
Select one of the following options:
• If you are performing additional adjustments, refer to the following
sections, as applicable:
– Adjusting Current Modes
– Adjusting Capacitance and Inductance (NI 4072 Only)
Caution For the NI 4072, adjusting the capacitance and inductance is required. Skipping
this step causes an incorrect adjustment of the device.
• If you are not performing additional adjustments, refer to one of the
following sections:
– Verification Procedures—to verify your new calibration
coefficients before saving them to the EEPROM
– Completing the Adjustment Procedures—if you do not want to
verify the adjustments you have just made
Adjusting Current Modes
If you do not use the current modes (DC and AC), or the accuracy is
insignificant for your application, you can skip this section and select one
of the following options:
• If you skip this section and you are calibrating an NI 4072, go to the
Adjusting Capacitance and Inductance (NI 4072 Only) section.
