Testing conditions and diode.
When the resistance of the circuit under test is not more than about 50Q , the buzzer emits a
continuous sound.
Read the measurement results from the display. When measuring DC voltage, the display also
shows the voltage polarity of the test point of red probe.
Press the power switch key and hold it for 2 seconds to turn off the meter power when the
measurement is done.
Warning
Do not input a voltage higher than 600V. It is possible to display a higher voltage value, but there
may be damage to the meter .
When measuring high voltage, be extremely careful of electric shock.
After completing all measurement and measurement operations, disconnect the probe from the
circuit under test.
Capacitance measurement
The resistance of the circuit under test is not more
than about 50, when the buzzer emits a continuous sound.
Forward DC current: about I mA;
open-circuit voltage: about 2.8V

Meter maintenance
This section provides basic maintenance information, including instructions for replacing the
fuse and replacing the battery. To avoid electric shock or personal injury, repairs should be performed
by qualified personnel with relevant information of calibration, performance test and maintenance .
Warning: In order to avoid possible electric shock, fire or personnel injury , do not
perform any measurement with the Meter when the outer casing is opened. Remove the
input signal before clean the meter.
