Important Safety Information
Electric shock hazard:
Unless measuring voltage, current, or frequency, shut off and lock out power. Make sure that all •
capacitors are discharged. Voltage must not be present.
Set the selector and connect the test leads so that they correspond to the intended measurement. •
Incorrect settings or connections can result in a blown fuse.
Using this unit near equipment that generates electromagnetic interference can result in unstable •
or inaccurate readings.
Failure to observe these warnings could result in severe injury or death.
Electric shock hazard:
Do not change the measurement function while the test leads are connected to a component or
circuit.
Failure to observe this precaution may result in injury and can damage the unit.
Electric shock hazard:
Do not use the tester to measure voltages in circuits that could be damaged or activated by the
AutoCheck™ mode’s low input impedance (approximately 3.0 kΩ and 150 pF).
Failure to observe this precaution may result in injury and can damage the unit.
Electric shock hazard:
Do not attempt to repair this unit. It contains no user-serviceable parts.•
Do not expose the unit to extremes in temperature or high humidity. Refer to “Specifications.”•
Failure to observe these precautions may result in injury and can damage the unit.
