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.
4. Press the MAX-RESET button to clear the 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.
4. Press the MAX-RESET button to clear the 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.
