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:
The fuse is an integral part of the overvoltage protection. When fuse
replacement is necessary, refer to “Specifications” for the correct type,
size and capacity. Using any other type of fuse will void the overvoltage
protection rating of the unit.
Failure to observe this warning could result in severe injury or death.
Electric shock hazard:
• Do not operate with the case or battery compartment open.
• Before opening the case or battery compartment, remove the test
leads from the circuit and shut off the unit.
Failure to observe these warnings could result in severe injury or death.
