Model DMM6500 6½-Digit Multimeter with Scanning Calibration and Adjustment Manual
Section 2: Performance verification
DMM6500-905-01 Rev. A/July 2018
2-3
Recommended test equipment
The following table summarizes the recommended calibration verification equipment. You can use
alternate equipment if that equipment has specifications that meet or exceed those listed in the table
below. Test equipment uncertainty adds to the uncertainty of each measurement. Generally, test
equipment uncertainty should be at least four times more accurate than corresponding DMM6500
specifications.
In this manual, the Model 8610 shorting plug is shown in the figures. However, you can use either
the Model 8610 or Model 8620.

Refer to the manufacturer's specifications to calculate the uncertainty, which varies for each function
and range test point.
Calibration verification limits
The calibration verification limits stated in this section have been calculated using only the DMM6500
one-year accuracy specifications and ambient temperature ±5 °C from T
CAL
(the temperature at which
the instrument was calibrated). They do not include test equipment uncertainty. If a particular
measurement falls outside the allowable range, recalculate new limits based on both the DMM6500
specifications and corresponding test equipment specifications.
Specifications and characteristics are subject to change without notice; please refer to the
