UNIT CALIBRATION
If the unit is not recording the proper temperature, use the following procedures.
If the
temperature is off by more than 10 degrees of actual
there is some other problem with
your unit.
(Do not attempt to re-calibrate)
.
The temperature adjustment trimmers are positioned behind the two front hole covers
(Main & Auxiliary) on the left side f the unit (refer to diagram).
HINT: Remove both the Main and Auxiliary covers and shine a flashlight through the holes
while looking through one hole to get an idea where the adjustment trimmer is located, this
will be very helpful.
NOTE: THE BACK TRIMMER IS FOR FACTORY USE ONLY, DO NOT
ADJUST.
Set the unit so it displays only the temperature that you are going to calibrate.
Place the appropriate temperature probe by a known accurate themometer and allow this
displayed temperature to stabilize.
HINT:
You can use ice water that is constantly stirred
for 32
°
F. Carefully insert a small to medium size jewelers type screwdriver approximately
1” into the appropriate hole. You will feel the screwdriver touch the trimmer. By gently
rotating the screwdriver, it will fall into the slot on the trimmer.
CAUTION:
Do not exert to much pressure with the screwdriver as you may damage the
component. If this happens, the unit may have to be returned for repair.
Observe the displayed temperaure and turn the trimmer very slightly until it reaches the
desired temperature. There is approximately an 8 second delay for temperature update so
be patient during this step. When finished, replace the hole covers.
