7½ Digit Graphical Sampling Multimeter Calibration Manual Section 3:
DMM7510-905-01 Rev. A / April 2015 3-3
The information in this section is intended for qualified service personnel only. Do not
attempt these procedures unless you are qualified to do so. Some of these procedures may
expose you to hazardous voltages, which could cause personal injury or death if contacted.
Use appropriate safety precautions when working with hazardous voltages.
Calibration cycle
Perform calibration at least once every one or two years to ensure that the instrument meets or
exceeds the specifications dictated by the customer requirements.
Calibration constants are stored in the nonvolatile memory of the Model DMM7510.
Recommended test equipment
The following table summarizes the recommended calibration 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 Model DMM7510
specifications. The following table lists the uncertainties of the recommended test equipment.

Refer to the manufacturer's specifications to calculate the uncertainty, which varies for each function
and range test point.
Instrument setup
Before adjusting calibration, make sure that the instrument is set up:
• To use the rear terminals
• For remote operation and TSP commands
• To the correct date and time
You also need to unlock calibration.
