4.7 Temperature measurement
• Set the rotary switch to the temperature position. Press "FUNC" to
switch between Celsius and Fahrenheit.
• Connect the positive end of the K-type thermocouple to the input jack
and the negative end to the COM jack.
• Place the tip of the thermocouple to the surface of the object to be
tested and read the measurement on the display.
WARNING
To avoid injury or damage to the meter,do not move the rotary
switch to the temperture position while measuring voltages
exceeding 30V.
4.8 Non-Contact Voltage (NCV) measurement
• Set the rotary switch to the NCV position.
• Move the top of the meter toward the voltage source. If voltage is
detected (>100V AC), the meter will beep and the NCV indicator will
flash. The closer to the voltage source the meter is, the faster the
meter will beep/flash.
Note:
• Even without indication, voltage may still be present. Do not rely
solely on NCV detection to determine the presence of voltage.
Detection could be impaired by socket design, insulation thickness, or
other factors.
• External interference sources could mistakenly trigger NCV indication.

4.9 Wireless Operation

• With the rotary switch in any position other than OFF, press
Wireless
enable the communication function of the meter.
• Open the app (iOS or Android) on the mobile device to be used and
search for the multimeter and establish a connection. Once connected,
the app will mirror the display of the meter and show any measurement
being performed.
• Press again to disconnect the meter from the mobile device.
