2. Insert the battery as indicated by the polarity symbols (+ and -
) marked inside the battery compartment.
3. Replace the battery door.
Notes: After you install or replace the battery, it takes time for
sampling once again both he temperature and humidity data. The
display will show full segment for 1 to 2 seconds, then shows the
updated tempera-ture and humidity reading.
Display and Functions
GENERAL OPERATION
ThisThermo-Hygrometerwill measure / displayindoor temperature
(the air temperature measured by the sensor built inside the unit )
or outdoor temperature (the air temperature measured by the
detachable external sensor probe )and indoor relative humidity (the
relative humidity measured by the sensor built inside the unit )
It can be set to display the indoor/outdoor maximum or minimum
temperature and indoor relative humidity recorded.
Note:
When the outdoor temperature is over the measuring range ,flashing
digit ‘-50’(°C) / ‘-58’(°F) appears on the display (below –50 °C /
-58 °F) or ‘70’(°C ) / ‘158’(°F) appears on the display (above +70
°C / +158 °F)
When the indoor temperature is over the operating range ,fades out
on the display (below 0 °C /+32 °F) or blacks out on the display
(above +50 °C / +122°F).
This Thermo-Hygrometer will continue to record the indoor /
outdoor maximum, indoor / outdoor minimum temperature and
humidity changes, whether displaying current, maximum or
minimum temperature readings.
HOW TO SELECT THE INDOOR OR
OUTDOOR TEMPERATURE DISPLAY
The unit can display the indoor temperature or outdoor temperature
reading. For changing display between indoor and outdoor by
pressing the [IN/OUT] button to update the temperature display.

Note :
The ‘IN’ indicator will be displayed whenever the temperature
display relates to indoor temperature and the ‘OUT’ indicator will
be displayed whenever the temperature display relates to outdoor
temperature.
1. Remove the protecting cap from the sensing port.
2. Plug the external probe into the sensor jack and push the [IN /
OUT] button to toggle to the outdoor display. The ‘OUT’
indicator appears from outdoor to indoor.
Push the [IN/ OUT]button once to toggle the reading to the indoor
display. The ‘IN’indicator is displayed.
(It’s up to end user’s desire to remove or keep the external sensor
probe to the main unit.)

HOW TO READ THE RELATIVE
HUMIDITYAND COMFORT INDICATORS
The unit shows the indoor relative humidity and such reading is
temperature compensated.At the same time , the comfort indicators
– COMFORT, WET or DAY will tell you if the current indoor
environment is comfortable, too wet or too dry. The comfort
indicators will appear on the display when the following conditions
are satisfied :
You may like to clear the memory occasionally, so to record the
maximum / minimum at a specified period.

HOW TO SELECT THE TEMPERATURE
UNITS OF MEASURE
The switch on the back of the Thermo-Hygrometer allows you to
select between degrees Celsius and Fahrenheit. Set the switch to
‘°C’for selecting Celsius and to ‘°F’for selecting Fahrenheit.
LOW BATTERY SIGNAL INDICATION
If the voltage of the battery becomes low, the ‘BATT’indicator will
be display at the top right corner of the display . Replace the
battery when the ‘BATT’ indicator is displayed.
HOW TO REST THE UNIT
If you Thermo-Hygrometer doesn’t operate properly, take out the
battery from the unit for 4 to 5 seconds, then reinstall the battery.
