To avoid electric shock and other injury please pay
attention to the following:
• Do not use the device if it is damaged. Check the
cover of the device before use. Pay extra attention to
the insulation near the connectors.
• Check the connecting cables, their insulation. If the
cables or the connectors are defective, replace them
or do not use the device.
• Do not use the device if it operates improperly. If you
have doubts, take the device to a service station.
• Do not use the device near explosive materials (gases,
vapors, powders)
• Do not measure higher voltage on the device than
indicated, not between the measuring connectors or
between one of them and the earthing.
• Verify the operation of the device before usage by
measuring a known voltage.
• When measuring current, turn off the device before
connecting it to the circuit. Make sure that the device
is connected to the measured circuit serially.
• Only use the designated spare parts to repair the
device.
• When measuring above 30 V AC RMS, 42 V peak, or 60
V DC voltage pay extra atenntion, because there is a
risk of electric shock.
• When measuring, connect the measuring pin on
the wire first, and then the one on the device to the
circuit.
• Do not use the device if the battery container lid or
any part of the cover is missing.
• To avoid incorrect measuring results, electric shock
and injury, replace the batteries right after the low
battery symbol is lit on the display.
Further risks:
If any of the measuring points are
connected to a dangerous voltage, this voltage may
appear on the other measuring pin as well.

To avoid damage to the device or the measured
circuit, please note the following:
• Disconnect the power cord and discharge the high
capacity capacitors before measuring resistance,
diode or continuity.
• Use the proper mode and threshold for measurement.
• Before measuring current always check the fuses and
turn off the measured circuit before connecting the
device to it.
• Remove the device from the measured circuit before
changing measuring mode with the switch.
• Remove the device from the measured circuit before
taking off the cover.
