Safety Information
Understand and follow operating instructions carefully.use the meter only as specified in
this manual; otherwise,the protection provided by the meter may be impaired.
WARNING
• If the equipment is used in a manner not specified by the manufacturer, the protection
provided by the equipment may be impaired.
• Always use proper terminals, switch position, and range for measurements.
• To reduce the risk of fire or electric shock, do not use this product around explosive
gas or in damp locations.
• Verify the Meter operation by measuring a known voltage. If in doubt, have the Meter
serviced.
• Do not apply more than the rated voltage, as marked on Meter, between terminals or
between any terminal and earth ground.
• To avoid false readings that can lead to electric shock and injury, replace the battery
as soon as low battery indicator blinks.
• Avoid working alone so assistance can be rendered.
• Do not use the Tester if the Tester is not operating properly or if it is wet.
• Individual protective device must be used if hazardous live parts in the installation
where the measurement is to be carried out could be accessible.
• Disconnect the test leads from the test points before changing the position of the
function rotary switch.
• Never connect a source of voltage when the function rotary switch is not in voltage
position.
• When using test leads or probes, keep your fingers behind the finger guards.
• Use caution with voltages above 30 Vac rms, 42 Vac peak, or 60 Vdc. These voltages
pose a shock hazard.
• Remove test lead from Meter before opening the battery door or Meter case.
• DO NOT USE the test leads when the internal white insulation layer is exposed.
• DO NOT USE the test leads above maximum ratings of CAT. environment, voltage
and current, that are indicated on the probe and the probe tip guard cap.
• DO NOT USE the test leads without the probe tip guard cap in CAT III and CAT IV
environments.
• Probe assemblies to be used for MAINS measurements shall be RATED as
appropriate for MEASUREMENT CATEGORY III or IV according to IEC 61010-031
and shall have a voltage RATING of at least the voltage of the circuit to be measured.
• Only replace the blown fuse with the proper rating as specified in this manual.
• Do not attempt a current measurement when the open voltage is above the fuse
protection rating. Suspected open voltage can be checked with voltage function.
• Never attempt a voltage measurement with the test lead inserted into the A input
terminal.
• Disconnect circuit power and discharge all high-voltage capacitors before testing
resistance, continuity and diodes.
