Important Safety Information
Electric shock hazard:
• Do not operate with the case open.
• Before opening the case, remove the test leads from the circuit and shut off the unit.
Failure to observe these warnings could result in severe injury or death.
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 incorrect measurements or damage to the unit.
• 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.
• Do not clamp the jaw around a conductor carrying a frequency greater than 400 Hz. The magnetic
circuitry may reach a hazardous temperature if this frequency is exceeded.
Failure to observe these precautions 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.
