7½ Digit Graphical Sampling Multimeter Calibration Manual Section 2:
DMM7510-905-01 Rev. A / April 2015 2-3
Recommended test equipment
The following table summarizes the recommended 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 Model DMM7510
specifications. The following table lists the uncertainties of the recommended test equipment.
