In this manual, a Warning identifies the conditions and
procedures that cause a dangerous situation to the user.
A Caution identifies the conditions and procedures that
could cause damage to the Meter, equipment under test
damage, or permanent data loss.
The symbols used on the Meter and in this manual are
shown in Table 1.
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. 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.
•Measure the test leads for continuity
before use. Do not use if the resistance
is high or noisy.
•Use only specified replacement parts in
the Meter.
•Keep fingers behind the finger
guards on the probes.
WCaution
To prevent damage to the Meter or to the
equipment under test, follow these
guidelines:
•Disconnect circuit power and discharge
all high-voltage capacitors before you do
diode tests or measure resistance,
continuity, or capacitance.
•Use the correct terminals, function, and
range for all measurements.
•Before a current measurement, do the
fuse test.
