2. Connect power to the SA1000X and warm up the probe for at least 30 minutes.
3. Configure the DMMs with the following settings:
Setting
DMM 1
DMM 2
Function
DC Voltage
Resolution
6.5 digits
Number of Averages
4
Auto Zero
Enabled
Range

1 V
4. Output a 5 V DC signal from the DC source.
5. Measure the 5 V signal with DMM 1; measure the output of the probe with
DMM 2.
6. Calculate the following:
Reading
DMM 1

− Reading
DMM 2
7. Verify that the result is <500 µV.
If the reading is outside this verification limit, return the probe to NI for repair. Refer
