Verifying zero values using a 4-wire short
Four-wire short verifications are not included in the Customer Calibration Data Report.
To verify zero values using a 4-wire short, you will:
• Check the zero values of various test points with 4-wire connections to the DMM6500 front or rear
terminals.
• Verify that the displayed readings are within specified limits.
Verify resistance zero values using a 4-wire short
To verify resistance zero values:
1. Select the 4W Res function.
2. Set the DMM6500 to the 1Ω range.
3. Press the MENU key.
4. Under Measure, 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.
