EN
GENERAL OPERATION
The unit has two operating modes: MAX/MIN DISPLAY
MODE and HI/LO DISPLAY MODE. To change from one
mode to another, press [MODE] button once.
MAX/MIN DISPLAY MODE:
hows the current temperature and the maximum and
minimum temperature at the same time.
NOTE Initially the ‘Max’ and ‘Min’ values will display the
same temperature values as the current temperature display
until changes in temperature are recorded.
HI/LO DISPLAY MODE:
hows the current temperature and the preset high and low
temperature alarm limit.
HOW TO SELECT THE INDOOR OR OUTDOOR
TEMPERATURE READING
The outdoor temperature will be measured if the outdoor
sensor probe is plugged in, and indoor temperature is
measured if the outdoor sensor probe is removed.
The outdoor sensor plug is located inside the battery
compartment.
To remove/plug in the outdoor sensor, slide the battery cover
in the direction of the arrow, then remove/insert the plug
toward/away from the battery.
HOW TO RESET THE MAXIMUM OR MINIMUM
MEMORIES
There are two ways to reset the Max / Min memories,
1. For resetting both memories – In the MAX/MIN DISPLAY
MODE, press the [MEMORY CLEAR] button once.
2. For resetting individual Max or Min memories – In the
MAX/MIN DISPLAY MODE, press either the [MAX] button
or the [MIN] button once to reset the respective memory.
The other memory will be unaffected.
NOTE Resetting a memory will result in current temperature
being displayed in the Max or Min memory display.

ABOUT THE TEMPERATURE ALARM
Whenever the alarm is activated, the alarm will sound for 1
minute when the current temperature rises and crosses the
high or low temperature alarm limit.
If the unit is left unattended, the alarm will stop automatically
after 1 minute to conserve power but will issue a 3-second
repeater ‘bee ’ sound every minute for up to 12 hours as a
continued warning that the temperature has moved outside
the alarm limit.
The repeater alarm will continue to sound even if the
temperature later returns to the allowed temperature band,
until the alarm is deactivated.
NOTE If the unit shows the MAX/MIN DISPLAY MODE,
the respective alarm indicator – either HI or LO will flash
continuously for up to 12 hours, or until the alarm is
deactivated.
If the unit shows the HI/LO DISPLAY MODE, the respective
alarm limit digit will flash continuously for up to 12 hours, or
until the alarm is deactivated.
HOW TO SELECT THE ON / OFF OF THE
TEMPERATURE ALARM
Activating the Alarm
1. lide the [ALARM ON / OFF] switch to the ON position
to activate the temperature alarm.
NOTE If the [ALARM ON / OFF] switch is in the OFF position
and the temperature has already risen / dropped and passed
the high or low limit, at that instant, no alarm will sound if
the [ALARM ON/OFF] is switched to the ON position so
that no alarm will sound.
Deactivating the Alarm
1. When the alarm sounds, the alarm can be stopped by
pressing either the [HI], [LO] or [MEMORY CLEAR]
buttons.
The Thermometer will sound the alarm again next time,
when the temperature rises and passes the high or low
temperature alarm limit.
2. lide the [ALARM ON / OFF] switch to the OFF position,
to switch off the alarm permanently.
NOTE Indoor high / low temperature alarm limit can be set
to work whenever the outdoor sensor probe is removed.
NOTE Outdoor high / low temperature alarm limit can be
set to work whenever the outdoor sensor probe is inserted
into the sensor jack.
HOW TO SET THE HIGH / LOW TEMPERATURE
ALARM LIMITS
The unit must show the HI/LO DISPLAY MODE to allow the
alarm to be set.
To set the high temperature alarm limit, press the [HI] button
to increase by 1° increments until the desired high
temperature alarm limit is displayed.

EN
The selecting range is from -50°C to +70°C (-58°F to
+158°F). Press and hold the [HI] button to select the high
temperature alarm limit more quickly.
To set the low temperature alarm limit, press the [LO] button
to increase by 1° increments until the desired low
temperature alarm limit is displayed.
The selecting range is from -50°C to +70°C (-58°F to
+158°F). Press and hold the [LO] button to select the low
temperature alarm limit more quickly.
HOW TO SELECT THE TEMPERATURE UNITS
OF MEASURE
The switch on the back of the Thermometer selects between
degrees Celsius and Fahrenheit. To select Celsius units,
set the switch to °C. To select Fahrenheit units, set the switch
to °F.
NOTE Reset the Thermometer unit after any change to
the temperature units.
HOW TO SELECT THE RATE OF SAMPLING
CYCLE
The switch on the back of the Thermometer selects between
NORMAL and FAST sampling cycle. To select a 60-second
sampling cycle, set the switch to NORMAL. To select a 10-
second sampling cycle, set the switch to FAST.
NOTE Reset the Thermometer unit after any change to
the sampling cycle.
THE RESET BUTTON
Uses a pointed object to push the reset button once, which
is located on the back of the unit, to update the display
whenever a change is made to either of the following:
1. Display unit changed to degrees Celsius or Fahrenheit,
2. Rate of sampling change to NORMAL or FAST sampling
cycle.
NOTE After resetting the unit, the high / low temperature
alarm limit setting will be cleared and reset to its preset value.
After resetting the unit, the minimum and maximum
temperature recorded will be reset.
LOW BATTERY SIGNAL INDICATION
If the voltage of the battery becomes low, all °C or °F digits
will flash. Replace the battery when °C or °F digits flash.
SECURING THE OUTDOOR SENSOR PROBE
You can mount the outdoor sensor probe by following these
steps below:-
1. Drive a screw (not included) into the wall at the location
that the outdoor sensor probe wire will be attached.
2. Route the outdoor sensor’s cord 3 m (10 ft) through the
window.
3. Hang the outdoor sensor’s wire attachment loop onto the
screw.

NOTE Locate the outdoor sensor probe away from the
direct sunlight and heavy precipitation.
FREE STANDING OR WALL MOUNTING
Stand
Flip out the plastic stand on the rear of the Thermometer for
table standing. tand the thermometer on a flat surface.
Wall Mount
You can mount your Thermometer on a wall by using a screw
(not supplied) with the screw head extending about 3.5mm
(0.14 in) from the wall.
NOTE For accurate measurement, you should mount the
Thermometer in an area where air can flow freely around it.
MAINTENANCE
The following suggestions will help you care for the
Thermometer so you can enjoy it for years.
1. Keep the Thermometer dry. If it gets wet, wipe it dry
immediately. Liquids might contain minerals that can
corrode the electric circuits.
2. Use and store the Thermometer only in normal
temperature environments. Temperature extremes can
shorten the life of electronic devices, damage the battery,
and distort or melt plastic parts.
3. Handle the Thermometer gently and carefully.
Dropping it can damage circuit boards and cause the
Thermometer to work improperly.
4. Keep the Thermometer away from dust and dirt, which
can cause premature wear of parts.
5. Wipe the Thermometer with a damp cloth occasionally
to keep it looking new. Do not use harsh chemical,
cleaning solvents, or strong detergents to clean the
Thermometer.
6. Use only fresh batteries of the required size and type.
Always remove old or weak batteries. They can leak
chemicals that can destroy electronic circuits.
7. Modifying or tampering with the Thermometer’s internal
components can cause a malfunction and might invalidate
its warranty.
