SAFETY
WARNING
• Improper use of this meter can cause damage, shock, injury or death.
Download, read and understand the User Manual before use.
• Use caution when working with signals > 60 V DC or 30 V AC RMS.
• Never ground yourself when taking electrical measurements.
• Keep your fingers behind the finger guards on the test lead probes.
• Turn off power to the circuit under test before opening the circuit.
• Always discharge capacitors and remove power from the device under test
before performing Diode, Resistance or Continuity tests.
• Never connect the meter leads across a voltage source while the function
switch is in the current, resistance, or diode mode.
• When changing ranges, always disconnect the test leads from the circuit
under test.
• Some test lead probe tips may not be long enough to reach the live parts
inside some voltage outlets because the contacts are recessed deep in
the outlets. As a result, the reading may show zero volts when the outlet is
actually live.
