Returning for Service Returning for Service
Before returning the instrument for service…
1. Install new Alkaline batteries in the proper alignment shown on the
door.
2. Examine the surface temperature probe tip for dirt or damage.
3. Perform a RESET. (pg. 10)
To return an instrument for service print out a service form on
our web site.
Why do the Surface Temperature and Air Temperature values differ
when holding the probe in the air and away from a surface?
The Ts sensor has a very quick response time. The Ta
sensor has a slower reaction time and requires additional
time to stabilize. This is most noticable when moving from
one temperature extreme to another.
Changing The Batteries Changing The Batteries
As the batteries become weak the symbol will appear
and begin flashing during measuring. If the batteries are
allowed to become very weak, this symbol will remain on
without flashing.
USE ONLY AA ALKALINE BATTERIES. Nickel-
cadmium and nickel-metal hydride rechargeable batteries will
work but the low battery symbol may stay on.
