Service Input Protection Measures
• Have your tools and machinery serviced
at The ToolShed with ToolShed replace-
ment parts. This will ensure that the safety
of the power tool or machine is maintained.
• The voltage limit is 600 Volts when meas-
uring voltage.
• The voltage limit is 250 ACV, or the equivalent
RMS voltage when the frequency, resistor,
buzzer, or the diode is measuring.
• The fuse (F200mA/250V) will work to protect
when the uA and mA is measuring.
• Do not use this meter when the meter or the
test pen appear broken in any way.
• If the meter is not used correctly as directed,
the inbuilt safety functions of the meter may
fail.
• Care must be taken when working around
bare conductors or buses, in order to prevent
electric shock or arc discharge, which may
cause injury.
• Do not use this instrument near explosive
gas vapour, or dust.
• The correct input function must be used to
measure specic ranges.
• The input value must not exceed the limit of
the input value specied for each range, in
order to prevent damage to the instrument.
• Do not touch the unused input while the
instrument is connected to the circuit during
testing.
• When the measured voltage exceeds 60 vDC
or 30 vAC, exercise caution to prevent electric
shock.
• When measuring with a test pen, ensure you
place your nger behind the guard ring of
the pen.
• Before converting the range, you must make
sure that the test pens have left the circuit
you are testing.
• Before carrying out a resistance, diode,
capacitance measurement, or continuity test,
the circuit under test must be powered o
and all high-voltage capacitors in the circuit
under test should be discharged.
• Do not measure the resistance on a live
circuit, or perform a buzzer test.
• When using this meter, you must comply
with all the standard safety regulations in the
following two aspects:
• Protection against electric shocks.
• Preventing the misuse of the instrument’s
safety procedures.
• To ensure your personal safety, please use
the provided test pen with the meter, check
all components before use, and make sure
they are fully intact.
• The use of these meter instruments near
devices with large electromagnetic distur-
bances will be unstable and may even cause
large errors.
WARNING
The warnings and precautions
discussed in this manual cannot cover
all possible conditions and situations
that may occur. It must be under stood
by the operator that common sense
and caution are factors which cannot
be built into this product, but must be

NOTE
NOTE
NOTE
Do not measure any voltage greater
than 600 Volts to prevent electric shock
or damage to the instrument or self.
Do not apply if there is more than 600V
voltage between the terminal and earth
to prevent electric shock or damage to
the instrument or self. To avoid damage to the meter under
test, all power to the circuit under test
should be cut o before measuring
resistance, and all high-voltage
capacitors should be fully discharged.
To avoid damage to the meter under

• The resistance value will show on the display
window.
• NOTES: The resistance value measured on
the circuit usually diers from the rate resist-
ance.
• To measure the low resistance accurately,
please short-circuit the two test pens to read
out the short-circuit resistance of the test
leads, then subtract it by the readings to get
an accurate resistance value.
• At 60 MΩ range, the reading will stabilise
after a few seconds, which is normal for high
resistance measurements.
• When the meter is not in circuit, the display
will show “OL”, indicating that the measure-
ment value is out of the measurement range.

the open circuit and ground exceeds
250 volts. If the fuse is blown during
measuring, you may damage the meter
or yourself. To avoid damage to the
meter or test equipment, use the correct
input socket, function, and range
before making measurements. When
the test pen is plugged into the current
input socket, do not connect the other
end in parallel to any circuit.
To avoid damage to the meter under
test, all power to the circuit under test
should be cut o before measuring on-
o of the circuit and all high-voltage
capacitors should be fully discharged.
• Connect the power supply of the circuit, then you can read the displayed reading. If the display
shows only “O L”, this indicates that the input exceeds the selected range. The rotary switch
should then be placed at a higher range.

MAINTENANCE
• When opening the instrument case or
removing the battery cover, ensure no test
pens are still connected to the ports.
• Please use authorised replacement parts
from the ToolShed to service the meter.
• Before opening the meter, all relevant power
must be disconnected. Also, you must ensure
that you do not carry any static electricity so
as not to damage to the meter.
• Instrument components, instrument calibra-
tion and maintenance operation instructions
should be performed by professionals.
• When opening the instrument housing,
some capacitance in the instrument may be
noticed. Even after the instrument is turned
o, dangerous voltages are kept.
• If the instrument displays any abnormality,
the table should be immediately stopped
and the meter sent in for repair. This is to
ensure that the meter will not be used before
proper inspection is completed.
• When the meter is not in use for a long
time, please remove the batteries, and avoid
storing in high temperature or humidity.
Battery & Fuse Replacement
General Maintenance/Cleaning
• Replace batteries and fuses to avoid electric
shock or personal injury caused by erroneous
readings. When the symbol appears on
the instrument display, replace the battery
immediately. Please follow the steps below
to replace the battery:
• Ensure you have turned o the meter.
• Pull all the test pens out of the input socket.
• Use a screwdriver to loosen the screws xing
the battery cover.
• Remove the battery cover
• Remove the old battery or the damaged fuse
• Replace the batteries or fuses with new ones,
contact your neares ToolShed if you require
parts or advise.
• Reinstall the battery cover and close the
screws until tight.
• In order to avoid electric shock or damage to
the instrument, there should be no charge
on the inside of the instrument. Before
opening the housing or the battery cover,
any connection to the test meter and the
input signal must be removed.
• Use a damp cloth, and a small amount of
detergent if needed, to clean the meter
housing. Do not use abrasives or chemical
solvents. If the input sockets become soiled
or wet, this may aect your readings.
OPERATION
Capacitance Measurement
Temperature Measurement
NCV Test
• Turn the rotary switch to position.
• Connect the black test pen and the red test
pen to the “COM” input socket and input
socket respectively.
• Measure the capacitance value of the circuit
under test with the other two ends of the
test pens. The reading will be shown on the
LED display window.
• NOTE: More time would be needed to
measure larger capacitors. Allow sucient
time depending on the size of your test.
• Take note of the polarities of the capacitor to
ensure you connect to each end correctly to
avoid any damage to the meter.
• Turn the Rotary Switch to the “°C (°F)” func-
tion, and the meter will show the surrounding
temperature.
• Take o the test pens and connect the
“COM” and “VΩmA” injects with the right
polarity ends of the thermocouples.
• The meter will show the approximate
temperature as read from the thermocouple.
• NOTE: Even if there is no indication that the
voltage is still there, you should not rely on
non-contact voltage detectors to determine
if there is a voltage detection operation
on the conductor. This may be aected by
factors such as socket depth, insulation thick-
ness, and type, to name a few.
• When the input voltage is put to the instru-
ment, due to sensing in the presence of
voltage, the voltage-sensing indicator light
may illuminate.
• Interference sources in the external environ-
ment, such as ashlights, motors, etc., may
accidentally trigger non-contact voltage
detection.
• Rotate the rotary switch to the NCV position
and place the top of the meter close to the
test conductor. If the meter detects the AC
voltage meter, the corresponding signal
strength indicator will light up according to
the detected signal strength (low–yellow,
high–red), and the buzzer will send out
dierent frequency alarms.
NOTE
To avoid damage to the meter or device
under test, all power to the circuit under
test should be cut o before measuring
capacitance. All high-voltage capacitors
should be fully discharged.
