touch button,value on display will be locked, touch
button again, to cancel reading hold.
4.2 Torch
1)Long press the flashlight button for 2 seconds, turn on
the flashliaht, and turn it off after about 1 minute.
4.3 Auto Power -Off
1) If no operation within 15 minutes after start,
there's
instrument will enter standby state, and shut down to
save energy.
2) After automatic shutdown, Press the "U" button, to
wake the instrument enter work state.
4.4To measure
1)Touch the electric source button to start the machine.
Ifthe battery voltage is insufficient,
the display willdisplay a lowvoltage symbol,
at which point the battery should be replaced.
Press the power button again to shut down the machine.
2)When the instrument is not measured, it will enter the
automatic scanning state. The instrument is shown as

4.7 DC voltage measurements
4.7.1 DC voltage measurements (V)
Connect the test pen to the signal being tested. When the
measured DC signal is greater than 0.5V, the display voltage
value When the measured DC signal is <0.5V, the instrument
uses the default resistance value and displays the resistance
value of the measured signal.
4.7.2 Dc voltage measurement(mV)
1)Press SEL button to dc voltage mV,

varying intensity.
4. 11Capacitance
measure
1. Press "SEL" key to switch to capacitance
2.Measure the capacitance with both ends of the test
pen and read the measurement from the LCD.
Notice:
OWhen measuring large capacitors, it takes
time to stabilizethe reading
2When measuring the capacitance with
polarity, pay attention to the corresponding
polarity to avoid damaging the instrument.
4. 12 Temperature
measurement
Press ""
SEL
key to switch TEMP, and the red plug of
the thermocouple is inserted into the C/°F end.The
black plug can be inserted into the COM jack. When
the reading is stable, the temperature value can be
read directly from the display screen.
Notice:
D The maximum temperature of the randomly
packaged K-type thermocouple is 250°C, and
the instantaneous measurement can be up to
300°C.
