Probe Supplied:
Model 4727-- Supplied with a standard probe sensor with cable. Both sensor and cable may be immersed in liquid. Probe sensor may be mounted using the supplied sensor holder and mounting screw.
Model 4227 & 4627-- Supplied with a bottle sensor and cable. Bottle sensor is filled with a patented nontoxic glycol solution that is GRAS (Generally Recognized As Safe) by the FDA (Food and Drug Administration) eliminating concerns about incidental contact with food or drinking water. The solution filled bottle simulates the temperature of other stored liquids. Velcro® and a magnetic strip are provided to mount the bottle to the inside of a refrigerator/freezer and to mount the display on the outside. The micro-thin probe cable permits refrigerator/freezer doors to close on it.
TEMPERATURE DISPLAY MODES Ambient Temperature Display Mode (IN):
Indicated by “IN” appearing on the display, displays the current ambient temperature and either the ambient temperature memory (MIN/MAX) or the ambient temperature alarm limits (LO/HI).
Probe Temperature Display Mode (OUT):
Indicated by “OUT” appearing on the display, displays the current probe temperature and either the probe temperature memory (MIN/MAX) or the probe temperature alarm limits (LO/HI).
To change between ambient (IN) and probe (OUT) temperature display modes, press the IN/OUT button located on the back of the unit.
To change between displaying the memory (MIN/MAX) and the alarm limits (HI/LO), press the MODE button.
DISPLAYING °F OR °C
To display the temperature readings in Fahrenheit or Celsius, press the °C/°F button located on the back of the unit.
MINIMUM AND MAXIMUM MEMORY
There are four points that are automatically recorded into memory:
Minimum (MIN) Ambient Temperature Achieved Maximum (MAX) Ambient Temperature Achieved Minimum (MIN) Probe Temperature Achieved Maximum (MAX) Probe Temperature Achieved
All four memories are independent of each other.
Minimum and maximum temperature memories are NOT programmable. The minimum temperature recorded into memory is the minimum temperature achieved since the last time the memory was cleared. The maximum temperature recorded into memory is the maximum temperature achieved since the last time the memory was cleared. The minimum and maximum temperature memories are maintained over the period since the memory was cleared.
Minimum and maximum memories are recorded for both ambient and probe temperatures regardless of the display mode.
CLEARING THE PROBE (OUT) TEMPERATURE MEMORY
1.Select the Probe Temperature Display Mode by pressing the IN/OUT button located on the back of the unit until “OUT” appears on the display.
2.Press the MODE button until “MIN” and “MAX” appears on the display.
3.Press the MIN-RESET button to clear the minimum temperature memory. The display will show “88.8” under MIN and will then display the new minimum temperature memory.
4.Press the MAX-RESET button to clear the maximum temperature memory. The display will show “88.8” under MAX and will then display the new maximum temperature memory.
CLEARING THE AMBIENT (IN) TEMPERATURE MEMORY
1.Select the Ambient Temperature Display Mode by pressing the IN/OUT button located on the back of the unit until “IN” appears on the display.
2.Press the MODE button until “MIN” and “MAX” appears on the display.
3.Press the MIN-RESET button to clear the minimum temperature memory. The display will show “88.8” under MIN and will then display the new minimum temperature memory.
4.Press the MAX-RESET button to clear the maximum temperature memory. The display will show “88.8” under MAX and will then display the new maximum temperature memory.
ALARMS
Both ambient (IN) and probe (OUT) temperature alarm limits may be set in 1° increments.
With the alarm enabled (֠), the unit will sound an alarm when the temperature being displayed is outside the alarm limits that have been set for that display mode (equal to or lower than the low alarm set point, or equal to or greater than the high alarm set point). Example: If the unit is displaying the ambient temperature (IN) and the probe
temperature (OUT) is outside the probe temperature alarm limits, no alarm will sound.
SETTING PROBE (OUT) TEMPERATURE ALARM LIMITS
1.Select the Probe Temperature Display Mode by pressing the IN/OUT button located on the back of the unit until “OUT” appears on the display.
2.Press MODE button until “LO” and “HI” appears.
3.To set the low temperature alarm limit (LO), press the LO ALM SET button to advance the display until the desired low temperature is displayed. Press and hold the LO ALM SET button to rapidly advance the display.
4.To set the high temperature alarm limit (HI), press the HI ALM SET button to advance the display until the desired high temperature is displayed. Press and hold the HI ALM SET button to rapidly advance the display.
SETTING AMBIENT (IN) TEMPERATURE ALARM LIMITS
1.Select the Ambient Temperature Display Mode by pressing the IN/OUT button located on the back of the unit until “IN” appears on the display.
2.Press MODE button until “LO” and “HI” appears.
3.To set the low temperature alarm limit (LO), press the LO ALM SET button to advance the display until the desired low temperature is displayed. Press and hold the LO ALM SET button to rapidly advance the display.
4.To set the high temperature alarm limit (HI), press the HI ALM SET button to advance the display until the desired high temperature is displayed. Press and hold the HI ALM SET button to rapidly advance the display.
ENABLE/DISABLE ALARMS
To enable the alarm to sound when the temperature being displayed is outside the alarm limits, press the ֠ button located on the back of the unit until “֠” appears on the display. Each successive press of the ֠ button will enable (֠) or disable the alarm.
ALARM SOUNDING
With the alarm enabled (֠), the unit will sound an alarm when the temperature being displayed is outside the alarm limits that have been set for that display mode (equal to or lower than the low alarm set point, or equal to or greater than the high alarm set point). If the alarm is sounding based on the low alarm limit, “LO” will flash on the display. If the alarm is sounding based on the high alarm limit, “HI” will flash on the display.
The unit will continue to alarm and flash the corresponding “LO” or “HI” until the temperature being displayed is within the alarm limits. Once the temperature being displayed is within the alarm limits, the alarm will stop sounding and the corresponding “LO” or “HI” will no longer flash.
To silence an alarm manually, press any button. When manually silenced, the corresponding “LO” or “HI” will continue to flash on the display until the temperature is within the alarm limits.
When enabled (֠), the alarm will only sound if the temperature being displayed is outside the alarm limits that have been set for that display mode (IN or OUT). Example: If the unit is displaying ambient temperature (IN) and the probe temperature (OUT) is outside the probe temperature alarm limits, no alarm will sound.
RESET BUTTON
The RESET button located on the back of the unit may be used to simultaneously reset the memory and alarm limits for both the ambient (IN) and probe (OUT) sensor.
To reset the unit, use a pointed object to press the RESET button.
When the reset button in pressed, the following will occur:
•The display will show all segments for approximately 5 seconds.
•The ambient (IN) and probe (OUT) minimum/maximum memory will be cleared.
•The ambient (IN) and probe (OUT) alarm limits will be returned to the factory default value of 10°C (LO) and 30°C (HI).
•The unit will display the ambient (IN) temperature in °C.
