If you find yourself in the field and needing to calibrate your Fieldpiece LT17A Digital Multimeter, there is a very simple solution. Calibrating the LT17A is easy even if you are on the job. Just fill a bucket of ice water to obtain a known temperature of 32°F (0°C) and place the thermocouple in the ice water. Then, adjust the TEMP OFFSET pot on the face of the LT17A's meter until it reads 32.0 (0.0).
