Verifying zeros using a 4-wire short
Four-wire short verifications are not included in the Customer Calibration Data Report.
Check the zeros of various test points with 4-wire connections to the Model DMM7510 front or rear
terminals. Verify that the displayed readings fall within specified limits.
Verify resistance zeros using a 4-wire short
To verify resistance zeros:
1. Select the 4W Res function.
2. Set the Model DMM7510 to the 1Ω range.
3. Press the MENU key.
4. Select Settings.
5. Set the Offset Compensation to On.
6. Connect the Model 8610 or 8620 4-wire short to the front panel, as shown in the following figure.
7. Allow to settle for 5 minutes. Do not use relative offset.
