During use
• If the device is used near noise generating equipment, the display may
become unstable or indicate large errors.
• Do not use the device or test leads if they appear to be damaged.
• Use the device only as specified in this manual, as otherwise the protection
provided by the device may be impaired.
• Use extreme caution when working near bare conductors or bus bars.
• Do not operate the device in the vicinity of an explosive gas, vapour or dust.
• Verify device operation by measuring a known voltage. Do not use the
device if it operates abnormally, as protection may be impaired. When in
doubt, have the device serviced.
• Uses the proper terminals, function and range for your measurements.
• If the magnitude of the quantity to be measured is unknown, initially set the
device to the highest possible range or, where possible, use the autorange
mode.
• To avoid damages to the device, do not exceed the maximum input values
shown in the technical specification tables.
• Do not touch unused terminals when the device is connected to a circuit
for measurement.
• Exercise caution when working with voltages above 60 VDC or 30 VAC RMS.
Such voltages pose a shock hazard.
• When using the probes, keep your fingers behind the finger guards.
• When making connections, connect the common (ground) test lead before
connecting the live test lead. When disconnecting, disconnect the live test
lead before disconnecting the common test lead.
• Before changing functions, disconnect the test leads from the circuit under
test.
• For all DC functions, including manual and autorange mode, first use the
AC function to check for any AC voltage to avoid the risk of shock. Then
select a DC voltage range equal to or greater than the AC range.
• Switch off power to the circuit and discharge all high-voltage capacitors
before measuring resistance, continuity, diodes, or capacitance.
• Never make resistance or continuity measurements on live circuits.
• Before measuring current, check the device's fuse and switch off power to
the circuit before connecting the device to the circuit.
• In TV repair work or when making measurements on power switching
circuits, remember that high transient voltages at the test points can
damage the device. Use a TV filter to attenuate any transients.
• Use only 3x AAA batteries, properly installed in the device's battery case,
to power the device.
• Replace the battery when the battery low indicator (
a low battery, the device may show incorrect readings that can lead to
electric shock or personal injury.
• Do not measure voltages above 1000V in Category III installations or 600V
in Category IV installations.
• The "REL" symbol is displayed when the device is in Relative Measurement
mode. Exercise caution because hazardous voltages may be present.
• Do not operate the device with the case (or part of the case) opened or
removed.

Instructions
• Remove the test leads from the device before opening the device case
or battery cover.
• When servicing the device, use only approved replacement parts.
• Before opening the device, always disconnect it from all sources of
electricity and discharge any static electricity, which can damage internal
components.
• Any adjustment, maintenance or repair work carried out on the device
while it is live must only be carried out by a suitably qualified person, taking
into account the instructions in this manual.
• A qualified person is someone who is familiar with the installation,
construction and operation of the equipment and the hazards involved.
A qualified person is trained and authorized to energize and de-energize
circuits and equipment in accordance with established practices.
• When the device is opened up, remember that some internal capacitors
can retain a dangerous voltage even after the device is switched off.
• If any faults or abnormalities are observed, take the device out of service
) appears. With
and ensure that it cannot be used until it has been checked out.
• If the device will not be used for a long time, remove the batteries and store
the device in a place with moderate temperature and relative humidity.
