4.21 Measuring Temperature (With T hermocouple)
& WARNING
Beware of electrocution.
To avoid electrical shock, do not connect the
thermocouples to charged circuits.
4.21.1 Turn the rotary selector to TEMP position.
4.21.2 "O L" will appear on the main display of the LCD
at this time.
4.21.3 Plug the red end of the 'K' type thermocouple
into the TEMP jack and black end into the COM
jack. Touch the surface of the object or a rea with
the temperature sensor for measurement.
4.21.4 Press the ''"C /"F" button to choose
·e
or "F
measurement.
4.21.5 Take the reading on the main indicator of the LCD.
Note:
The cold end compensation circuit used for measuring
temperature is placed inside the front part of the meter.
lt may take a longer time to reach thermal balance with
the environment. Therefore the meter should be
exposed to the environment for a longer time for
accurate reading.
4.22 Measuring Sound Level (dB)
& WARNING
To avo id damage to the meter, do not connect
the input plug to any electric signal.

4.22.1 Turn the rotary selector to the dB range position.
4.22.2 Point the sensor located in the front part of the
meter at the sound source.
4.22.3 The sound level in dB will be shown on the LCD.
Note:
Strong wind (over 1 Om/sec.) striking on the microphone
may cause misreading for measurement in windy
locations. A windscreen should be placed in front of the
microphone in such circumstances.
4.23 Measuring Luminance
& WARNING
To avoid damage to the meter, do not connect
the input plug to any electric signal.
4.23.1 Turn the rotary selector to the Lux or x 1 O Lux
range position.
4.23.2 Point the sensor located in the front part of the
meter at the light source.
