BATTERY & FUSE
The low battery symbol '
DIGITAL
the internal 9V battery is low (<7.5V), indicating that
MULTIMETER
the battery should now be replaced. If the meter does
not function on the DCA range, the internal 500mA
fuse may have blown. To replace the battery or fuse,
remove the test leads from the meter and remove the
two screws from the rear cover. Replace the battery
or fuse and then reassemble.
WARRANTY STATEMENT
Applicable only to product sold in Australia

acceptable quality and the failure does not amount to a major failure.
TRANSISTOR CHECK
' will be displayed when 1. Set the Function switch to the 'hFE' setting.
2. Turn the meter 'ON'
3. Connect the component leads of the transistor to the
correct pins of the transistor jack (Emitter, Base &
Collector) depending on whether it is a NPN or PNP
type; you may need the component specification
sheets to help you identify this.
4. The meter will display the hFE measurement.
DIODE CHECK MEASURING RESISTANCE
1. Connect the RED test lead to the 'VΩmA' jack and 1. Connect the RED test lead to the 'VΩmA' jack and
the BLACK test lead to the 'COM' jack the BLACK test lead to the 'COM' jack
2. Set the Function switch to the ' ' setting. 2. Set the Function switch to the correct 'Ω' range.
3. Turn the meter 'ON' 3. Turn the meter 'ON'
4. Connect the test probes across the diode, Positive 4. Connect the test probes across the Resistance to
probe (RED) to the 'anode' and Negative probe be measured. Ensure that the component or circuit
(BLACK) to the 'Cathode'. under test in not energised.
5. If the diode is functioning the meter should display
the diode forward Voltage drop, usually between
500–700mV.
MEASURING DC CURRENT
(UP TO 10A)
1. Connect the RED test lead to the '10ADC' jack and
the BLACK test lead to the 'COM' jack
2. Set the Function switch to the '10A' setting.
3. Turn the meter 'ON'
4. Connect the test probes so that the meter
becomes part of the circuit to be measured.
Ensure that the circuit load is less than 10Amps or
the meter will be damaged.
