Preparing for the Performance Tests
XW Warning
To prevent possible electric shock or personal injury:
• Do not perform the following procedures unless qualified to do so. Some procedures involve
the use of high voltages.
• Before handling the test connections and in between tests, make sure the calibrator is in
standby mode (STBY).
To prepare for the performance test:
1. Make sure that you have the required equipment (see Table 2).
2. Warm up the calibrator as required by its specifications.
3. Allow the temperature of the DUT to stabilize at room temperature: 23 °C ±5 °C (73 °F ±9 °F)
4. Check the fuses and battery and replace them if necessary. See Fuse Test (115, 117) and Battery and Fuse
Replacement.
To verify the accuracy of the DMM functions, do the following:
1. Connect the Calibrator to the VΩ and COM input terminals on the Meter.
2. Turn the rotary switch to the function listed in each step of Table 3 (110, 114, 115, 116, 117) or
Table 4 (113).
3. Apply the input level for each step listed in Table 3 (110, 114, 115, 116, 117) or Table 4 (113).
4. Compare the reading on the Meter display with the Display Reading in Table 3 (110, 114, 115, 116, 117) or
Table 4 (113).
If the display reading falls outside of the range shown, the Meter requires calibration adjustment or repair.
Testing Temperature (116 only)
Connect the K-type thermocouple to the temperature input of the Meter and temperature calibrator. To ensure
an accurate measurement, the Meter and the thermocouple connector must be at the same temperature. After
connecting the thermocouple to the Meter, allow the junctions to stabilize before recording the displayed
reading. This can take several minutes, depending on temperature gradients.
