TEST PASS
If the measured resistance is within ± 5k Ω of the tabulated value, the thermistor is functioning
correctly.
TEST FAIL
If the measured resistance varies greatly from the tabulated value or an open circuit is detected, the
thermistor is faulty and should be replaced (refer to section
8.5 Adjust internal temperature correlation
Purpose:
To adjust the internal temperature calibration so that the display temperature matches the
temperature at the base of the fridge.
This adjustment should only be necessary if the thermistor has been replaced.
NOTE :
A display temperature within 2-3°C (3.6-5.4°F) of the actual temperature at the base
of the fridge is within normal on/off cycle temperature variation. If this is the case,
the internal temperature calibration should not be changed.
Procedure:
Connect the fridge to 12/24V DC or 100-240V AC.
Turn the fridge on.
Press and hold
and
simultaneously until “A 0” appears on the display.
Push
or
to adjust the setting.
Continue pressing
or
until the desired adjustment is made.
After 5 to 6 seconds of inactivity, the display will flash twice and return to displaying the current
target temperature.
Allow the fridge to cycle on and off a few times to allow for any temperature lag.
Check the temperature display against the temperature at the base of the cabinet.
CALIBRATION SUCCESSFUL
If the temperature display is within 2-3 °C (3.6-5.4°F) of the temperature at the base of the fridge,
return the unit to the customer and advise that this is within normal on/off cycle temperature variation.
REPEAT CALIBRATION
If the temperature display is not within 2-3 °C (3.6-5.4°F) of the temperature at the base of the fridge,
repeat the calibration procedure above.
