Resistance
Before testing a resistor in a circuit, make sure that all
power is removed from that circuit, and that all
1. Plug the test leads into their respective sockets.
2. Select the required range.
3. Short out the leads, and turn the adjuster located on the
side of the meter, until a zero reading is obtained.
4. Connect the leads to the resistor to be tested and take the
reading from the scale.
NOTE: If the range is changed, the needle must be re-zeroed before
taking a reading.
WARNING:
capacitors are discharged.
Battery Test
1. Plug the test leads into their respective sockets.
2. Connect the red test lead to the positive terminal of the
battery, and the black test lead to the negative.
3. The meter will indicate whether battery is serviceable or not.
Battery and Fuse replacement.
1. Disconnect test leads to ensure there is no possibility of them
being connected to a circuit.
2. Remove the single retaining screw from theback cover, and
remove cover.
3. Prise out Battery or Fuse from their holders, and replace with
one of the same size and rating.

Operation
Before operating this meter, and to ensure accurate readings, the
needle must be set to zero, by turning the adjuster screw, in the
centre of the meter,as necessary.
On no account must the voltage under test exceed 500V D/C
WARNING:
A/C rms
D/C Voltage
1. Plug the black test lead into the “-” socket, the red lead into
the “+” socket.
2. Set range selector to D/C volt range required
IMPORTANT: If the voltage is not known beforehand, then select the
highest range and work down until a satisfactory reading is obtained.
3. Connect red test lead to the positive polarity of the circuit,
and black test lead to the negative.
4. Take the reading from the appropriate scale.

A/C Voltage
1. Plug the test leads into their sockets.
2. Set the range selector to the A/C voltage range required.
IMPORTANT: If the voltage is not known beforehand, then select
the highest range and work down until a satisfactory reading is
obtained.
3. Connect the test leads to the circuit regardless of polarity.
4. Take the reading from the appropriate scale.
D/C Current
Maximum current must not exceed 250mA
1. Plug the black test lead into the “-” socket, the red lead into
the “+” socket.
2. Set the range selector to the D/C current range required.
IMPORTANT: If the Current is not known beforehand, then select
the highest range and work down until a satisfactory reading is
obtained.
3. Switch off the current to the circuit, and break where
required.
4. Connect the test leads in series with the circuit, the red
lead to the positive polarity, and black test lead to negative,
and switch on the current.
5. Take the reading from the appropriate scale.
