4.20 HUMIDITY MEASURING
4.20.1 Set the transform switch at the %RH range position.
4.20.2 The 'LCD' display will show the current environment humidity.
NOTE:
• When the tested environment humidity value changed. It need to a few minutes to get the
stable "RH" reading.
4.21 SOUND LEVEL (dB) MEASURING
4.21.1 Set the transform switch at the dB range position.
4.21.2 Move the sensor in front of the meter to the sound source in a horizontal position.
4.21.3 The 'LCD' display will show the current sound level (dB).
NOTE:
• The Fast response is suitable to measure sudden bursts and peak values from sound source.
• Strong wind (over 10m/sec.) striking the microphone can cause misreading for measurement in windy locations; a
windscreen should be used in front of microphone.
4.22 ILLUMINANCE MEASURING
4.22.1 Set the transform switch at the Lux or ×10Lux range position.
4.22.2 Move the sensor in front of the meter to light source in a horizontal position.
4.22.3 The 'LCD' display will show the illuminance at the meter.
NOTE:
• When only the figure 'OL' is displayed, it indicates overrange situation and the higher range has to be selected.
• 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.
• Recommended Illumination:
