MEASURE CONNECTIVITY

• 

Scroll the rotary knob to “    ”, press the “FUNC.” button and switch 

to connectivity measurement function, and ensure that the power 

supply of the measured circuit has been cut off. 

• 

Insert the red probe into the “    ” socket, and the black probe into 

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.

WARNING

• 

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 “    ” position, press “FUNC.” button and 

switch to capacitance measurement function. 

• 

Insert the red probe into the “    ” socket, and the black 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.

WARNING

• 

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 “    ” function, press “FUNC.” button and 

switch to diode measurement function.

• 

Insert the red probe into “    ” socket, and the black probe into the 

“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.

WARNING

• 

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.
