While in transit, your cabinet is subjected to more jarring and
vibration than at any other time, and the display may require
some adjustment at start-up. Refrigerators are designed to
maintain 38° to 40°F (3.3° to 4.4°C) and Freezers -2° to 0°F
(-19° to -18°C). During periods of heavy use, when doors
are opened repeatedly or remain open for extended period,
or if warm product is loaded in the cabinet, the temperature
displayed may temporarily exceed the “normal” range. This is
common, as warm air outside the cabinet mixes with cold air
inside. If your thermometer continues to display temperature
above “normal” range, close the doors, make sure they seal
tight and keep them closed for at least 30 minutes. If a high
temperature is still displayed, check the thermometer by plac-
ing a pre-calibrated temperature sensing device in the center
of the refrigerated compartment and keep the doors closed for
at least 15 minutes. The thermometer should display the same
temperature as the sensing device, within +/-2°F (+/-1°C). If
it does not, follow instructions below for calibration mode to
adjust the offset.
ADJUSTING PROGRAM SETTINGS
Press ‘SET’ on front to display settings in this order:
HSP
-40 to 199
= High Alarm Set Point
= High Set Point value*
LSP
-40 to 199
= Low Alarm Set Point
= Low Set Point value*
HI
-40 to 199
= High temperature log
= Highest temperature recorded since reset last
pressed (Press Reset to clear value)
LO
-40 to 199
= Low temperature log
= Lowest temperature recorded since Reset last
pressed (Press Reset to clear value.)
CAL
= Calibration Mode
-30 to 30 = Calibration temperature display offset value*
Calibration example: If sensing device in cabinet reads 38° and thermometer
displays 41°, press ‘SET’ 10 times, to display temperature offset value. Then
press down arrow three times, to decrease offset by 3°. (If original offset value
displayed was “0”, then “-3” will appear).
*To adjust value, press up or down arrow until desired setting is
displayed. Then press ‘SET’ to save.
IMPORTANT: If sequence is interrupted for more than 15
seconds, or not completed to where the display flashes
once, unit will automatically revert back to temperature
mode, WITHOUT saving new values (tamper resistant).
If you need additional help, please contact the factory.
