OPERATION
1. Turn on the unit by pressing the On/Off Button (3, Fig. 1) once.
2. Press the °F/°C Button to select the desired temperature unit. (2, Fig. 1)
3. Immerse the probe tip at least 10 millimeters into the desired substance to

obtain temperature reading.

4. Press the H/T button (5, Fig .1) once to “freeze” the display at the current

temperature reading. “HOLD” flashes in the upper portion of the display
indicating that the unit is in hold mode. Press the H/T button again to release the
reading.

5. Press the MAX/MIN button (7, Fig. 1) once to recall the minimum temperature.

“MIN” will appear on the display.

6. Press the MAX/MIN button once again to recall the maximum temperature.

“MAX” will appear on the display.

7. After 3 seconds, the unit will automatically return to the current temperature and

“Min” or “Max” will no longer appear on the display.

8. To back light the display, press the LIGHT button (6, Fig. 1). The display will

light for 3 seconds.

9. The unit will automatically turn itself off after one hour to conserve power. To

turn off this function, press Clear (10, Fig. 1) and On/Off (3, Fig. 1). To restore
this function, turn the unit off and back on again by pressing the On/Off button
two times.

10. A stand is located on the back of the unit. Simply pull the bottom of the stand

away from the unit to extend the stand for use. Press the stand back into the unit
until it snaps to close. Also located on the back of the unit is a clip.

11. With the stand extended, pull it gently away from the unit to expose the battery

compartment and probe cable.

SETTING THE ALARM
1. Press and hold the Low Alarm Button (11, Fig. 1) until the desired temperature is

reached. “LOW” will appear in the display. When the current temperature is at or
below this set value, an alarm will beep.

2. The alarm will continue to beep four times every minute until the Alarm Off

Button (8, Fig. 1) is pressed or the current temperature returns to an “in range”
reading.

3. Press and hold the High Alarm Button (12, Fig. 1) until the desired temperature

is reached. “HIGH” will appear in the display. When the current temperature is at
or above this set value, an alarm will beep.

4. When both a High and Low alarm temperature are set, “HI LOW” will appear in

the lower portion of the display.

5. To clear the alarms, press the Alarm Off button (8, Fig. 1).

MEMORY
1. Press the H/T button (5, Fig. 1) to hold the current temperature. Press the

Memory button (4, Fig. 1) to store the temperature reading into memory. “Mem
1” will appear on the display. Repeat these steps to store additional
temperatures. Up to 10 readings can be stored.

2. To recall a stored reading, press the Recall Button (9, Fig. 1) once. The

temperature stored in Mem 1 will be displayed. Each subsequent press of the
Recall Button will show the next stored reading.

3. To clear all stored memories, press and hold the Clear Button (10, Fig. 1) for 5

seconds.

LOW BATTERY
Erratic readings, a faint display, or no display are all indicators that the battery is low
and needs to be replaced. To remove the battery, using a small screwdriver, unscrew
the three screws located on the back of the thermometer inside the probe
compartment. Remove the battery cover. Remove the exhausted battery and replace it
with a new 357 size battery. Make certain the positive (+) side is visible. Replace the
battery cover. Screw the three screws back into the unit. Do not over-tighten the
screws as this may cause damage to the battery cover. Close the probe compartment.

ALL OPERATIONAL DIFFICULTIES
If this thermometer does not function properly for any reason, please properly replace
the battery with a new G-13 battery (see Low Battery section, above). Low battery
power can occasionally cause any number of “apparent” operational difficulties.
Replacing the battery with a new fresh battery will solve most difficulties.
