Current Measurements - Fluke 183 User Manual

This calibrates the meter for the operating environment.
display. If you hear an error beep, the offset is greater than 5 C. You can
repeat this calibration at any time. To undo this calibration, return the meter to
factory settings by pressing both the yellow (shift) button and
powering up the meter (see Table 3. Power-up Options).
To insure accuracy of temperature measurements, you should follow this
procedure when using other K-type thermocouple probes with the 183/185
DMMs because accuracy specifications vary in different types of probes.
Observe proper polarity on the probe adapter and do not calibrate
the offset immediately following high amperage measurements.
