Battery & Fuse Replacement

DANGER

Never open the battery compartment cover while making measurement.

To avoid possible electrical shock, disconnect the test probe before

opening the cover for battery and fuse replacement.

Replacement fuse must be have the following rating.

Fast acting type, F 500mA/600V,

φ

6.35

×

32mm

7-1 Battery Replacement

Disconnect the test probe from the instrument.
Open the battery compartment cover by unscrewing the metal captive

screw to reveal battery compartment. Always replace all six batteries
with new ones at the same time.
Battery type: 6 x 1.5V battery type R6P, 1.5V AA or equivalent

Screw the battery compartment lid back on before using the instrument.

7-2 Fuse Replacement

Disconnect the test probe from the instrument.
Open the battery compartment cover by unscrewing the metal captive

screw to reveal battery compartment and replace the fuse.
Fuse type: 500mA/600V (F) quick acting ceramic fuse 6.35 x 32mm

Screw the battery compartment lid back on before using the instrument.

CAUTION

Install batteries in correct

polarity as marked inside.

CAUTION

Never press the test button if the live circuit warning lamp is lit or the

warning buzzer sounds. This may damage the circuit.

In case that an additional operating circuit is connected in parallel to the

circuit under measurement, the measurement error might be caused

due to the effects of impedance of the circuit connected in parallel or

transient current.

Set the range selector switch to the desired position 3( or 500(.
Short the line probe (red) and the earth clip of the test probe (black) and

press the test button. Adjust the ohm zero adjust to zero the pointer on
the scale.

Connect the test probes to the circuit under test.
Check the circuit under test is not energized as follows.

Connect the test probe to the circuit under test and read a voltage value.

If the circuit is live, the meter indicates the voltage, the live circuit lamp is

lit, and warning buzzer sounds. If the meter indicates 0V, the circuit is
dead

Press test button. Read the blue ohm scale directly.

Continuous Measurement
A lock down feature is incorporated on the test button. Pressing and
turning it clockwise, lock the test button in the continuous operating
position.
To release the lock turn the test button counterclockwise.
Never leave the test button locked down when not is use.

● Principle of Continuity Testing (Resistance Test)

Resistance value can be obtained by applying a
certain current to the resistance under test and
measuring the voltage generated on the both
sides of the resistance under test.

Resistance value = Voltage / Current

RX = V / I
