MEASURE CONNECTIVITY

•
Scroll the rotary knob to "
to connectivity measurement function, and ensure that the power
supply of the measured circuit has been cut off.
•
Insert the red probe into the "
the "COM" socket.
•
Contact the probe to the measured circuit or both ends of the
resistance.
•
If the resistance of the measured resistance or circuit is lower than
50Ω, the buzzer will sound.
•
At the same time the resistance of the measured circuit is displayed on the screen.
•
Before measuring resistance, connectivity, capacitance or diode, please turn off
the power supply and discharge all the high voltage capacitors, otherwise it may
cause damage to the instrument, electric shock or personal injuries.

MEASURE CAPACITANCE

•
Scroll the rotary knob to the "
switch to capacitance measurement function.
•
Insert the red probe into the "
"COM" socket.
•
Contact the probe to both ends of the capacitor.
•
After the reading is stable, read the measurement result on the
screen.
•
Before measuring resistance, connectivity, capacitance or diode, please turn off
the power supply and discharge all the high voltage capacitors, otherwise it may
cause damage to the instrument, electric shock or personal injuries.

MEASURE DIODE

•
Turn the rotary knob to the "
switch to diode measurement function.
•
Insert the red probe into "
"COM" socket.
•
Contact the red probe to the anode of the measured diode, and the
black probe to the cathode of the measured diode.
•
Read the measurement results on the screen.
•
If the polarity of the probe and the diode are opposite, the instrument will display
"OL", which can be used to differentiate the anode and cathode of the diode.
•
Before measuring resistance, connectivity, capacitance or diode, please turn off
the power supply and discharge all the high voltage capacitors, otherwise it may
cause damage to the instrument, electric shock or personal injuries.
Note: The instrument can display values as high as 1.5V forward bias. A typical diode
forward bias is in the range from 0.3V to 0.8V. However, readings may be different due
to the different resistances of other circuits between the probes.
