Measuring Humidity
Humidity Measurement for indoor:
Set the function switch to the ON position.
Remove the meter place to the room.
Read the %RH in the display for about two hours.
Measuring Light
Set the function switch to the green "lux" scale and set the range to desired ("lux" or "x10 lux") range.
Remove the meter and face the photo detector to light source in a horizontal position.
Read the illuminance nominal from the LCD display.
Over-range: If the instrument only display one "1" in the M.S.D. the input signal is too strong, and a higher range should be selected.
When the measurement is completed. Replace the photo detector from the light source.
Spectral sensitivity characteristic: To the detector, the applied photo diode with filters makes the spectral sensitivity characteristic almost meet C.I.E. (International Commission on Illumination) photopia curve V (λ) as the following chart described.

Insert the red test lead banana plug into the V/Hz%/Ω/Cap/°C jack.
Indicate "OL" "MΩ" on the display.
Touch the test probe tips across the circuit or part under test. It is best to disconnect one side of the part under test so the rest of the circuit will not interfere with the resistance reading.
Read the resistance in the display.
Measuring Sound Level
Set the function switch to the green "dB" position.
Remove the meter and face the microphone to sound source in a horizontal position.
The C-weighting curve is nearly uniform over the frequency range from 30 to 10,000Hz, thus giving an indication of overall Sound level.
The Fast response is suitable to measure shout bursts and peak values from sound source.
The sound level will be displayed.
Note: Strong wind (over 10m/s) striking the microphone can cause misreading for measurement in windy locations, a windscreen should be used in front of microphone.
Measuring Temperature
Temperature Measurement for Outdoor:
Set the function switch to the green "0.1°C" position or "1°C" position.
Then the display will show the environment temperature reading value °C directly.
Insert the black plug of temperature probe the COM jack and red plug to the "V/Hz%/Ω/Cap/°C" jack.
Touch the end of the temperature sensor to the area or surface of the object to be measured. The display will show the temperature reading value °C directly.
