WARNING: OBSERVE ALL SAFETY
PRECAUTIONS WHEN MEASURING HIGHER
VOLTAGES AND/OR CURRENTS. TURN-
OFF POWER TO THE CIRCUIT UNDER
TEST. REAPPLY POWER. IF AN ERRONEOUS
READING IS OBSERVED, DISCONNECT
POWER IMMEDIATELY AND RECHECK ALL
SETTINGS AND CONNECTIONS.
Safety Tips.
• Do not try to measure any voltage greater
than 1000V DC or 750V AC RMS.
• Voltages above 60V DC or 25V AC RMS
may constitute a serious shock hazard.
• Do not attempt to use this Meter if either
the Meter or the test leads have been
damaged.
• Turn-off power to the circuit under test
before cutting, unsoldering or breaking
the circuit. Small amounts of current can be
dangerous.
• Disconnect the live test lead before
disconnecting the common test lead.
• When using the test leads, keep your
fingers away from probe contacts. Always
grip behind the finger guards on the probes.
• Use a current clamp if measuring any
current above 10 Amps.
