THERMISTOR THERMOMETERS
(Please note that the following procedure reflects the Model 600 series and
later thermometers. When testing the Model 500, follow these instructions
where possible.)
1. Set the thermometer to Monitor Mode and Fahrenheit (ºF) following the
instructions in the Users' Manual for the instrument to be tested.
2. Extract the probe from its holder, but do not load a probe cover.
3. Lift the flap and insert the probe fully into the small hole in the top of
the 9600 Tester (the probe will go in approximately 1 3/4").
4. Wait 2 minutes for the temperature to fully stabilize.
5. Verify that the reading on the thermometer is within the following
tolerances:
96.4ºF Setting:
106.0ºF Setting:
See "Level 2 Calibration Test" to test units outside of these limits.
CELSIUS-ONLY THERMISTOR THERMOMETERS
1. Where possible, follow the instructions for the Model 600 series
Thermometer.
2. The Fahrenheit Mode is the preferred mode for calibration testing of
thermometers, because the temperature units (degrees) are smaller, and
give a more accurate test. Therefore, whenever possible, use this mode.
3. For Celsius-Only Units, use the following conversion table for testing
the calibration of the thermometer.
