Cleaning the Meter
Wipe the case with a damp cloth and mild detergent. Do not use abrasives or solvents. Dirt or moisture in the
terminals can affect readings.
Performance Tests
XWWarning
To avoid electric shock, do not perform the performance test procedures unless
the Meter is fully assembled.
The following performance tests verify the complete operation of the Meter and check the accuracy of each Meter
function against its specifications. The recommended calibration interval is 12 months. If the Meter fails any part of
the test, calibration adjustment and/or repair is indicated.
In the performance tests, the Meter is referred to as the unit under test (UUT).
Required Equipment
Table 4 lists the equipment required to conduct a performance test on the Meter.

- Check the fuses and battery and replace them if necessary refer to testing the fuses and replacing the battery and fuse 9
- Compare the reading on the meter display with the display reading in table 5 9
- Connect the calibrator to the v ω and com input terminals on the meter 9
- If the display reading falls outside of the range shown in table 5 the meter requires calibration adjustment or repair 9
- Testing temperature 116 only 9
- 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 9
