5. DMM (HI and LO)
2. Connect power to the SA1000X and warm up the probe for at least 30 minutes.
3. Configure the DMM with the following settings:
■
Function: DC voltage
■
Resolution: 6.5 digits
■
Number of Averages: 4
■
Auto Zero: Enabled
■
Range: 100 mV
4. Measure the signal at the DMM.
5. Verify that the DMM reading is ±100 µV.
If the reading is outside this verification limit, return the probe to NI for repair. Refer
