Electric shock hazard:
• Unless measuring voltage, shut off and lock out power. Make sure
that all capacitors are discharged. Voltage must not be present.
• 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 use the tester to measure voltages in circuits that could be
