3.2.7 Frequency measurement
Use for TTL/CMOS level. Do not measure Frequency on high voltage (>24V) to
avoid electrical shock hazard and/or damage to the instrument.
The Meter can measure Frequency.
To measure frequency:
1. Set the rotary switch to the Hz range.
2. Insert the black and red test leads into the COM and Hz input terminals.
3. Connect the test leads tip in parallel with the circuit to be measured. And
don't touch any electrical conductors.
4. Read the result directly from the display.
NOTE:
In noisy environment, it is preferable to use shield cable for measuring small
signal.

3.2.8 Temperature measurement
To avoid electrical shock and/or damage to the instrument, do not apply any
voltage source between the °C terminal and the COM terminal.
To avoid electrical shock, do not use this instrument when voltages at the
measurement surface exceed 60V DC or 24V RMS. AC. To avoid damage or
burns. Do not make temperature measurement in microwave ovens.
To measure temperature:
1. Set the rotary switch to ºC range and the LCD will show the current
environment temperature.
2. Insert 'K' type thermocouples into the COM terminal and ºC terminal (or
you can insert it by using Multi Function Socket).
Takings care to observe the correct polarity.
3. Touch the object with the thermocouple probe for measurement.
4. Read the stable reading from LCD.
3.2.9 NCV (Non-Contact Voltage detect)
Set rotary switch to the
range.
Put the EF-DETECT AREA close to the AC power cable or the power socket,
if AC electrical voltage is present, the Buzzer warning will sound, and the
symbol bar "–" will be displayed on the LCD.
The lowest detect voltage is around 50V 50/60Hz.
The LCD display EF, when detect the AC voltage signal, the LCD display
'–'/'– –'/'– – –'/'– – – –' from weak to strong.
This function is depending model.
