4.1 POWER-UP
Press the “ ” button to turn the Humidity Temperature Meter ON or OFF.
4.2 HUMIDITY MEASUREMENT
For measurement, place the sensor probe in the tested environment.
NOTE:
• Measurement Range: 0%~100%RH
• Operating Environment: Relative humidity: 0 to 85%RH, Temperature: 0℃~40℃, 32℉~104℉ (without
dew).

℉。
• Operating Environment: Relative humidity: 0 to 85%RH, Temperature: 0℃~40℃, 32℉~104℉ (without
dew).
4.4 SELECTING THE TEMPERATURE SCALE
When the meter was first power on, the default scale setting is set at Celsius℃ scale. The user may change it
to Fahrenheit ℉ by pressing “
℉℉℉℉
” button and vice versa to Celsius by pressing “
℃℃℃℃
” button.
4.5 MAX/MIN MEASUREMENT:
4.5.1 When one press the "MAX MIN" button the meter will enter the MAXIMIN mode. Under this mode the
maximum value, minimum value is kept in the memory simultaneously and updated with every new data.
When the MAX symbol is display, the Maximum is shown on the display.
4.5.2 Press "MAX MIN" again, then the MIN symbol is on the display and also the minimum reading.
4.5.3 Press "MAX MIN" again, MAX, and MIN will blink together. This means that all these data is updated in

the memory and the reading is the present temperature and humidity.
4.5.4 Press "MAX MIN" again, MAX will go back. One may press "MAX MIN" to circulate the display mode
among these options.
NOTE:
When the meter is under "MAX MIN" operation, "

"
button in "MAX MIN" mode, there will be two continuous beep.) To exit the MAX/MIN mode, one may press
and hold "MAX MIN" for 2 seconds.
4.6 READ HOLD
The user may hold the present reading and keep it on the display by pressing the "HOLD" button. When the
held data is no longer needed, one may release the data-hold operation by pressing "HOLD" button again.
NOTE:
When the meter is under Data Hold operation, the "MAX MIN" and "
℃℃℃℃
", "
℉℉℉℉
" button are disabled. (when you
press "
℃℃℃℃
", "
℉℉℉℉
" and "MAX MIN" button in HOLD mode, there will be two continuous beeps.)

4.7 TIMER OPERATION
One may start the timer by press the "TIMER" button. The counting can be stopped or continued by pressing it
again.
When the counting exceed 59min 59sec, the time scale will be changed to hours and minutes. The counting
can be reset by press and hold "TIMER" button for 2 sec.
4.8 BACK LIGHT
If the light is dark to make the reading difficult when measuring, you can press “ ” button to open the back
light which will last for 15 sec. You can close it up at any time once press “ ” button again.
NOTE:
• LED is the main source of back light. Its working current is large, often use back light will shorten the battery
life, you’d better not to use the back light so frequently unless it’s necessary.
• When the battery voltage is less than 7V, it will show “ ”. But if you use back light at the same time, maybe
“ ” will come up even if the battery voltage is more than 7V, because the working current is higher and the
voltage will decline. (When “ ” shows, the accuracy of the measurement can not be assured.)

You need not replace the battery. When you use normally (back light is not using), “ ” will not show up. You
need replace it till “ ”show again.
4.9 AUTO POWER OFF
By default, when the meter is powered on, it is under auto power off mode The meter will power itself off after
30 minutes if no key operation and no RS232 communication. Combination at power on can disable auto
power off.
One may press and hold "HOLD" button and then power on the meter and there will be two successive beeps
to indicate that auto power off is disabled and the will not show up.
4.10 DIGITAL OUTPUT
The Digital Output is a 9600bps N 81 serial interface.
4.11 BATTERY REPLACEMENT
