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.
