instruments with an over-voltage category (CAT II) and pollution 2
3-2 Follow all safety and operating instructions to ensure that the meter is used
safely and is kept in good operating condition.
3-3 Safety symbols:
important safety information, refer to the operating manual.
Danger - high voltage.

4. User Precautions
4-1 For safe use of the meter, use only the test leads supplied. If your test leads
are damaged make sure they are replaced with leads of the same quality and
specification.
4-2 Always use the meter with the blue holster in place.
4-3 Always check that the range switch is set to the correct position for the test
being made.
4-4 Do not exceed the maximum inputs shown on the dial or in these instructions.

7. OPERATING INSTRUCTIONS
7-1Attention before operation
7-1-1Check 9V battery. If the voltage is less than 7V, display will show “ ”,
the battery should be replaced to ensure accurate measurement.
7-1-2 Pay attention to the “ ” beside test lead sockets, printed beside it is the
maximum value for the input voltage or current for each socket.
7-1-3 The range switch should be set to the range to be measured before testing.
7-2 Measuring DC Voltage
7-2-1 Connect the black test lead to COM socket and the red to VΩmA socket.
7-2-2 Set the rotary switch to a suitable V (voltage) range position.
7-2-3 Connect test leads across the source or load to be measured.
7-2-4The voltage reading appears on the LCD.The polarity is indicated along with
the voltage value.
NOTE:
1.If you are not sure of the range to be measured, set the range switch to the
maximum (600V) setting and then reduce the range until you get a reading.
2.If the LCD shows ‘1’ or ‘-1’, it indicates that you need to switch to a higher voltage
setting.
3.Do not try to measure voltages exceeding 600V, it may be possible to get a
reading, but your meter may be damaged and you risk receiving an electric shock.
4.Take extra care to avoid contact with live surfaces when measuring high
voltages.
7-3 Measuring AC Voltage
7-3-1 Connect the black test lead to COM socket and the red to VΩmA socket.
7-3-2 Set the rotary switch to a suitable V~ range position.
7-3-3 Connect test leads across the source or load to be measured.
7-3-4 The voltage reading appears on the LCD.
NOTE:
1.If you are not sure of the range to be measured, set the range switch to the
maximum (600V) setting
2.If the LCD shows ‘1’ or ‘-1’, it indicates that you need to switch to a higher voltage
setting.
3.Do not try to measure voltages exceeding 600V, it may be possible to get a
reading, but your meter maybe be damaged and you risk receiving an electric
shock.
4.Take extra care to avoid contact with live surfaces when measuring high
voltages.
7-4 Measuring DC Current
7-4-1Connect the black test lead to COM socket and the red to the VΩmA socket
for a maximum 200mA current, for a maximum 10A current, move the red lead to
the 10A socket.
7-4-2 Set the rotary switch to a suitable A range position.
7-4-3 Connect test leads in series with the load to be measured.
7-4-4 The current reading appears on the LCD. The polarity will be indicated along
with the current value.
NOTE:
1.If you are not sure of the range to be measured, set the range switch to the
maximum (10A) setting.
2.If the LCD shows ‘1’ or ‘-1’, it indicates that you need to switch to a higher
range setting.
3.When the VΩmA socket is used do not exceed 200mA as this will blow the
fuse. Although the 10A socket is not fused do not exceed 10A current and do
not leave connected for more than 1 sec to avoid overheating the meter.
3.When the input is not connected, i.e. the circuit is open, the figure ‘1’ will be
displayed for the over-range condition.
4.When checking in-circuit resistance, be sure the circuit under test has all power
removed and that all capacitors have been discharged fully.
5.If you are not sure of the range to be measured, set the range switch to the
maximum resistance (2MΩ) setting.
7-6Measuring Temperature
7-6-1Set the rotary switch at the ˚C range position.
7-6-2The LCD will show the current temperature of the environment.
7-6-3When measuring temperature with the thermocouple supplied, insert the ‘K’
type thermocouple probe red plug into theVΩmA socket and the black plug
into the COM socket)
7-6-4You can get a reading from the LCD.
7-6-5To improve the accuracy of temperature measurement, leave the meters'
back light switched off during measurement.
7-7Transistor Testing
7-7-1Set the rotary switch at ’hFE’ position.
7-7-2Determine whether the transistor under test is NPN or PNP and locate the
emitter, base and collector leads. Insert the leads into the correct holes of hFE
socket on the front panel.

(the polarity of the red lead is ‘+’)
7-8-2Set the rotary switch to the range position.
7-8-3Connect the red lead to the anode and the black lead to the cathode of the
diode to be tested.
7-8-4You can get a reading from LCD.
NOTE:
1. The meter will show the approximate forward voltage drop of the diode.
2. If the lead connections are reversed, the reading will be ‘1’ .
7-9 Continuity Testing
7-9-1Connect the black test lead to the COM socket and the red to VΩmA socket.
7-9-2Set the rotary switch at the range position.
7-9-3Connect the test leads across two points of the circuit to be tested.
7-9-4If continuity exists (i.e. resistance is less than about 50Ω), the built-in buzzer
will give a continuous tone.
NOTE:
If there is no continuity or the resistance is greater than 50Ω, the reading will
be ‘1’ .
8. Maintenance
8-1 Make sure test leads are disconnected from any circuit under test before you
open the case or remove the battery cover.
8-2 To avoid electrical shock, disconnect test leads from circuit under test before
replacing the fuse. For protection against fire, replace fuses only with specified
ratings: F-200mA/250V fuse.
8-3 Replace the test leads immediately if they are damaged or conductor is
exposed, make sure replacement leads are of the same quality and specification
as the test leads supplied.
8-4 Use only moist fabric with a small amount of detergent for cleaning - do not use
solvents or abrasive materials.
8-5 Do not use the meter if the back cover is not properly closed (screwed tight
shut). If your meter shows any sign of malfunction, stop operation immediately
and send the meter for maintenance.
8-6 Remove the battery if your meter is not going to be used for a long time.
