- Turn the rotary switch to the function listed in each step of table 5
- To verify the accuracy of the dmm functions do the following
- 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
- Testing temperature 116 only
- If the display reading falls outside of the range shown in table 5 the meter requires calibration adjustment or repair
- Connect the calibrator to the v ω and com input terminals on the meter
- Compare the reading on the meter display with the display reading in table 5
