INFORMATION ON WASTE DISPOSAL FOR CONSUMERS OF 

ELECTRICAL & ELECTRONIC EQUIPMENT.

When this product has reached the end of its life it must be treated 

as Waste Electrical & Electronics Equipment (WEEE). Any WEEE 

marked products must not be mixed with general household waste, 

but kept separate for the treatment, recovery and recycling of the 

materials used. Contact your local authority for details of recycling 

schemes in your area.

Made in China. PR2 9PP

V.1.0

pole of the diode being measured and the black one to the negative pole. 

Read the approximate forward voltage drop of the diode on the display.

Circuit On-Off Measurement

•  Insert the black probe into the COM jack and the red one into the 

V.Ω.mA

 

jack.

•  Turn the switch to the      position and connect the probes in parallel with 

two points of the circuit being measured. If the resistance between the 

two points is less than 100Ω, the built-in buzzer will sound to indicate the 

continuity between the two points.

Temperature Measurement

•  Turn the switch to the 

°C

 position and insert the black probe of the 

thermocouple sensor into the COM jack and the red into the 

V.Ω.mA

 jack. 

•  Place the operating terminals (temperature measurement terminals) onto 

or inside the object being measured and directly read the temperature 

value in 

°C

 on the display.

•  When the switch is turned to the °C position and the sensor is in an open 

circuit, the display shows room temperature.

Replacement of battery and fuse

•  Under normal conditions it is unnecessary to replace the fuse.

•  Do not replace it until the probes are unplugged and the power is shut 

down. Take out the two screws of the rear cover to remove the housing.

• 

The specification of the fuse is:

- F1 250mA/250V, F210A/250V

(Any replacement should be of the same specification.)

•  The battery for this multimeter is 9V NEDA 1604 or 6F22.

•  Do not put the instrument into use until the rear cover is screwed after 

replacing the battery or fuse.
