Symbols - Bahco BMMTRS1 Original Instructions Manual

ENGLISH
• Do not operate the meter around explosive gas, vapor, or dust.
• Verify a Meter's operation by measuring a known voltage. Do not use the Meter if it operates abnor-
mally. Protection may be impaired. When in doubt, have the Meter serviced.
• Uses the proper terminals, function, and range for your measurements.
• When the range of the value to be measured is unknown, check that the range initially set on the
multimeter is the highest possible or, wherever possible, choose the auto-ranging mode.
• To avoid damages to the instrument, do not exceed the maximum limits of the input values shown
in the technical specification tables.
• When the multimeter is linked to measurement circuits, do not touch unused terminals.
• Caution when working with voltages above 60Vdc or 30Vac rms. Such voltages pose a shock
hazard.
• When using the probes, keep your fingers behind the finger guards.
• When making connections, connect the common 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 or auto-ranging, to avoid the risk of shock due to possible
improper reading, verify the presence of any ac voltages by first using the ac function. Then select
a dc voltage range equal to or greater than the ac range.
• Disconnect circuits power and discharge all high-voltage capacitors before testing resistance, con-
tinuity, diodes, or capacitance.
• Never perform resistance or continuity measurements on live circuits.
• Before measuring current, check the meter's fuse and turn off power to the circuit before connecting
the meter to the circuit.
• In TV repair work, or when carrying out measurements on power switching circuits, remember that
high amplitude voltage pulses at the test points can damage the multimeter. Use of a TV filter will
attenuate any such pulses.
• Use just one 6F22 battery, properly installed in the Meter's battery case, to power the Meter.
• Replace the battery as soon as the battery indicator (
might produce false readings that can lead to electric shock and personal injury.
• Do not measure voltages above 1000V in Category III, or 600V in Category III installations.
• When in REL mode, the "REL" symbol is displayed. Caution must be used because hazardous
voltage may be present.
• Do not operate the Meter with the case (or part of the case) removed.
