SETTING THE TIME-OF-DAY/DATE
Slide the DISPLAY switch to the DATE TIME position, the display will show the time-of-day and date.
While in the time-of-day/date display, pressing the SELECT button will allow the date and time to be set.
Pressing the SELECT button will cause the digits to ash in the following order Year→Month→Day→Hours→ Minutes →12/24 hour time→No digits ashing (value set). Once the desired item is ashing, pressing the
ADVANCE button will increment the value.
With the desired time-of-day/date appearing on the display, press the SELECT button until no digits are
ashing on the display. The time-of-day/date will be saved.
Note: While in the setting mode, if no button is pressed for fteen (15) seconds, the unit automatically exits from the setting mode.
VIEWING THE TIME-OF-DAY/DATE
To view the time-of-day/date, slide the DISPLAY switch to the DATE TIME position.
DISPLAYING °F OR °C
To display the temperature readings in Fahrenheit or Celsius, slide the °C/°F button to the desired position.
DISPLAYING PROBE 1 OR PROBE 2
Slide the PROBE switch to the desired position (1 or 2) to display the desired temperature sensor readings.
MINIMUM AND MAXIMUM MEMORY
There are four points that are automatically recorded into memory:
•Minimum (MIN) Probe 1 (P1) Temperature Achieved with time-of-day and date achieved
•Maximum (MAX) Probe 1 (P1) Temperature Achieved with time-of-day and date achieved
•Minimum (MIN) Probe 2 (P2) Temperature Achieved with time-of-day and date achieved
•Maximum (MAX) Probe 2 (P2) Temperature Achieved with time-of-day and date achieved
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 sensors regardless of the display mode.
VIEWING MIN/MAX MEMORY
1.Slide the PROBE switch to the desired position (1 or 2) to display the desired temperature sensor readings.
2.Slide the DISPLAY switch to the MIN MAX position. The display will show the current temperature and minimum/maximum memory for the selected probe.
VIEWING MIN/MAX MEMORY DATE/TIME
1.Slide the PROBE switch to the desired position (1 or 2) to display the desired temperature sensor readings.
2.Slide the DISPLAY switch to the MIN MAX position. The display will show the current temperature and minimum/maximum memory for the selected probe.
3.Press the EVENT DATE TIME button, the minimum temperature achieved by that probe along with the time-of-day/date the temperature was achieved will appear on the display (indicated by MIN and TIME appearing on the display).
4.Press the EVENT DATE TIME button a second time, the maximum temperature achieved by that probe along with the time-of-day/date the temperature was achieved will appear on the display (indicated by MAX and TIME appearing on the display).
Note: If no button is pressed for fteen (15) seconds, the unit automatically returns to the current temperature display mode.
5.To exit from the memory display mode, press and release the EVENT DATE TIME button until MIN or MAX no longer appears on the display, or simply do not press any button for fteen (15) seconds.
CLEARING THE MINIMUM/MAXIMUM MEMORY
1.Slide the PROBE switch to the desired position (1 or 2) to display the desired temperature sensor readings.
2.Slide the DISPLAY switch to the MIN MAX position. The display will show the current temperature and minimum/maximum memory for the selected probe.
3.Press the CLEAR MIN MAX button to clear the minimum and maximum memories for the probe being displayed.
ALARMS
Both temperature sensor (P1/P2) alarm limits may be set in 0.1° increments. Probe 1 and Probe 2 alarm limits are set independent of each other.
With the alarm switch set to the ON position:
-The unit will sound an alarm and ash the corresponding
LED (P1/P2) when the temperature measured is outside the alarm limits that have been set (equal to or lower than the low alarm set point, or equal to or greater than the high alarm set point).
-The alarm will sound regardless of which sensor is being displayed and regardless of the display mode. Example: If Probe 1 is being displayed and the DISPLAY switch is set to MIN MAX, but Probe 2 reaches an alarm condition, the alarm will sound and the P2 LED will ash.
SETTING THE TEMPERATURE ALARM LIMITS
1.Slide the PROBE switch to the desired position (1 or 2) to display the desired temperature sensor readings.
2.Slide the DISPLAY switch to the ALARM position. The display will show the current temperature and low/high alarm set points for the selected probe.
3.While in the alarm display mode, pressing the SELECT button will allow the alarm limits to be set.
Pressing the SELECT button will cause the digits to
ash in the following order: LowAlarm 1st Digits→Low Alarm 2nd Digit→LowAlarm Decimal Digit→ HighAlarm 1st Digits→HighAlarm 2nd Digit→HighAlarm Decimal Digit→No digits ashing (value set).
4.Once the desired item is ashing, pressing the
ADVANCE button will increment the value.
5.With the desired alarm set points appearing on the display, press the SELECT button until no digits are ashing on the display. The alarm settings will be saved.
Note: While in the setting mode, if no button is pressed for fteen (15) seconds, the unit automatically exits from the setting mode.
VIEWING THE TEMPERATURE ALARM LIMITS
1.Slide the PROBE switch to the desired position (1 or 2) to display the desired temperature sensor readings.
2.Slide the DISPLAY switch to the ALARM position. The display will show the current temperature and low/high alarm set points for the selected probe.
ENABLE/DISABLE ALARMS
To enable the alarm to activate when a temperature measured is outside the alarm limits, slide the ALARM switch to the ON position.
When the alarm is enabled, both Probe 1 and Probe 2 alarm set points will be monitored. If either sensor reaches an alarm condition, the alarm will activate. It is not possible to enable the alarm for one sensor and disable the alarm for the other sensor.
To disable the alarm so that no alarm sounds when a temperature measured is outside the alarm limits, slide the ALARM switch to the OFF position.
ALARM SOUNDING
With the alarm enabled, the unit will sound an alarm and the corresponding (P1/P2) red LED will ash when a temperature being measured is outside the alarm limits that have been set (equal to or lower than the low alarm set point, or equal to or greater than the high alarm set point). Until it has been acknowledged/silenced (see the “Acknowledge/Silence An Alarm” section), the alarm will sound and corresponding (P1/P2) red LED will ash continuously for the rst sixty (60) seconds. After 60 seconds, the alarm will sound and LED will ash for ten
(10) seconds every minute.
If the alarm is sounding based on the low alarm limit and the probe temperature is being displayed, “LO ALM” will also ash on the display. If the alarm is sounding based on the high alarm limit and the probe temperature is being displayed, “HIALM” will ash on the display.
The alarm will sound and corresponding LEDwill ash regardless of which sensor is being displayed and regardless of the display mode. Example: If Probe 1 is being displayed and the DISPLAY switch is set to MIN MAX, but Probe 2 reaches an alarm condition, the alarm will sound and the P2 LED will ash.
Theunit will continue to alarmand ash the corresponding
(P1/P2) red LED until the alarm has been acknowledged/ silenced by either pressing the SILENCE ALM button or by sliding the ALARM switch to the OFF position (see the “Acknowledge/Silence An Alarm” section). The unit will continue to alarmand ash the corresponding (P1/P2) red
LED even if the temperature being measured returns to an in-range/non-alarm condition.
ACKNOWLEDGE/SILENCE AN ALARM
While alarming, the alarm may be acknowledged/silenced in one of the following ways:
1.Slide the ALARM switch to the OFF position. Setting the ALARM switch to the OFF position will silence the alarm, but when it is switched back to the ON position, if the temperature being measured is still in an alarm condition, the alarm will sound. Setting the ALARM switch to the OFF position prevents any/all alarms from sounding.
