Safety Information
A Warning identifies hazardous conditions and actions that could cause bodily harm or death.
A Caution identifies conditions and actions that could damage the Meter, the equipment under test, or cause
permanent loss of data.
XWWarning
To prevent possible electrical shock or personal injury, follow these guidelines:
• Use this Meter only as specified in this manual or the protection can be compromised.
• Do not use the Meter if it is damaged. Before you use the Meter, examine the case. Look
for cracks or missing plastic. Carefully look at the insulation around the terminals.
• Make sure the battery door is closed and locked before you operate the Meter.
• Replace the batteries when the battery indicator () appears.
• Remove the test leads from the Meter before the battery door on the Meter base is
opened.
• Examine the test leads for damaged insulation or exposed metal. Measure the test leads
for continuity. Do not use if resistance is high or noisy. Replace damaged test leads
before you use the Meter.
• Do not apply more than the rated voltage, shown on the Meter, between the terminals or
between a terminal and earth ground.
• Do not operate the Meter with the battery door removed or the case open.
• Be careful around voltages >30 V ac rms, 42 V ac peak, or 60 V dc. These voltages pose
a shock hazard.
• Use only the replacement fuse specified by the manual.
• Use the correct terminals, function, and range for measurements.
• Do not work alone.
• For current measurements, connect the Meter to the circuit after you remove circuit
power. Always put the Meter in series with the circuit.
• Connect the common test lead before the live test lead and remove the live test lead
before the common test lead.
• Do not use the Meter if it operates incorrectly. Protection can be compromised. If you
are unsure, have the Meter examined.
• Do not use the Meter around explosive gas, vapor or in damp or wet environments.
• Use only specified 1.5-V AA batteries (three in the Meter base and two in the display),
correctly installed, for Meter power.
• Comply with local and national safety requirements when in hazardous locations.
• Only use test leads that have the same voltage, category, and amperage ratings as the
Meter and that are approved by a safety agency.
• Measure a known voltage first to make sure that the Meter operates correctly. If you are
unsure, have the Meter examined.
• Use protective equipment, as directed by local or national authorities when in
hazardous work areas.
• Use only specified replacement parts in the Meter.
• Keep fingers behind the finger guards on the probes.
