Short press this button to enter/exit the data hold mode, and long press
(about 2s) this button to turn on/off the backlight (the backlight will
automatically turn off after 60s).
1 - SELECT button

2 - HOLD/BACKLIGHT - SELECT button
Short press this button to enter the maximum/minimum measurement
mode and long press this button to exit (only valid for AC/DC voltage, AC
current, resistance and temperature measurement).
3 - MAX/MIN button
In the cappacitance and voltage positions, press this button to store the
current reading as a reference for future readings. When the LCD display
value is reset to zero, the stored reading will be subtracted from the
future readings. Press this button again to exit the relative value mode.

Turn the function switch to the AC/DC voltage position, and connect
the test leads with the measured load or power supply in parallel.

Turn the function switch to the position, press the SELECT button
switch to select resistance measurement, and connect the test leads
with both ends of the measured resistance in parallel.
Note :
Note :
The current measurement must be taken within 0°C 40°C. Do not
suddenly release the trigger, as the impact will change the reading for
a short time.

Do not input voltage above 600V. Althought it is possible to measure
higher voltage, it may damage the meter.
Be cautious to avoid electric shock when measuring high voltage.
When the measured voltage is 30V (AC) or 60V (DC), the LCD will
display the high voltage alarm prompt.
To ensure measurement accuracy, center the conductor in the jaws.
Otherwise, + 1.0% additional error in reading will be produced.
If the LCD displays «OL», it indicates that the current is over range
and there is a danger of damage to the meter.

Note :
If the mesured resistor is open or the resistance exceeds the
maximum range, the LCD will display «OL».
Before measuring the resistance online, switch off the power supply of
the circuit, and discharge all capacitors to avoid inaccurate
measurement.
If the resistance is not less than 0.5 when the test leads are
short-circuited, please check the test leads for looseness or other
abnormalities.
Do not input voltage higher than 30V to avoid personal injury.
Before measuring the continuity online, switch off the power supply of
the circuit, and fully discharge akk capacitors.
If the diode is open or its polarity is reversed, the LCD will display
«OL».
Before measuring the diode online, switch off the power supply of the

If the measured capacitor is short-circuited or the capacitance
exceeds the maximum range, the LCD will display «OL».
When measuring capacitance 400 F , it may take some time to
steady the readings.
Before measuring, fully discharge all capacitors (especially for
capacitors with high voltage) to avoid damage to the meter and user.
Note :
The electric field sensing sensitivity is divided into two levels (»EFHI» and
«EFLo»). The meter defaults to «EFHI». Select different sensitivity level
