Test Procedure:
1. Turn on the verifier device, using either a 9-volt battery or the power supply. Make
sure the red LED is illuminated.
2. Allow device ~5 minutes for warm-up and stabilization time.
3. Allow certified master or the two reference thermometers and the instrument to be
tested to acclimate in the same ambient temperature for at least 10 minutes.
4. For all instruments, make sure the lens at the tip of the probe is clean. To clean, use
an alcohol prep or a swab dipped in alcohol, followed by a damp wipe with water to
remove any residue.
5. Alternately insert the reference instrument(s) and the instrument being verified into
the aperture opening, comparing the readings.
NOTE

Accuracy Limits: Comparison between the reference instrument(s) and the
instrument being verified should be within ±0.4 ºF (0.2 ºC) for acceptable limits.
If not, repeat the process. In the event they still differ by more than the
acceptable limits, call Exergen for repair or replacement of the failed
instrument.
