DC Voltage Verification
Before you do the dc voltage verification:
1.
Make sure you have the necessary equipment. See Table 2.
2. Make sure the Meter battery is good and replace it if necessary. See Battery Replacement .
3. Warm up the Calibrator as necessary. Refer to the specifications for the Calibrator.
4. Let the temperature of the UUT become stable to room temperature.
Start the dc voltage verification.
1.
Follow the instructions to enter Maintenance mode (see Start Maintenance Mode ) and then:
a. Push

until TEST shows on the display.
b. Push

. The Meter is in verification mode.
2. Connect the Calibrator to test leads and three of the six leads in the cable, as shown in Figure 5. (The white lead
connects to the NORMAL Hi terminal of the 5522A. The yellow and black leads connect to the NORMAL LO
terminals.)
3. Apply the input level for each value shown in Table 3 and compare the UUT indication on the display with the
UUT reading limits.
If the display indication falls outside of the range shown in Table 3, calibration adjustment or repair is necessary.
