A Warning identifies condition and procedures that are dangerous to the user. A Caution
identifies conditions and procedures that can cause damage to the Product or the
equipment under test.
XW Warning
To prevent personal injury, use the Product only as
specified, or the protection supplied by the Product can be
compromised.
To prevent possible electrical shock, fire, or personal injury:
• Read all safety Information before you use the
Product.
• Carefully read all instructions.
• Use only correct measurement category (CAT),
voltage, and amperage rated probes, test leads, and
adapters for the measurement.
• The battery must be locked in place before you
operate the Product.
• Recharge the battery when the low battery indicator
shows to prevent incorrect measurements.
• Do not apply more than the rated voltage, between the
terminals or between each terminal and earth ground.
• Limit operation to the specified measurement
category, voltage, or amperage ratings.
• Do not exceed the Measurement Category (CAT)
rating of the lowest rated individual component of a
Product, probe, or accessory.
• Measure a known voltage first to make sure that the
Product operates correctly.
• Do not touch voltages > 30 V ac rms, 42 V ac peak, or
60 V dc.
• Do not use the Product around explosive gas, vapor,
or in damp or wet environments.
• Do not use, and disable the Product if it is damaged.
• Do not use the Product if it operates incorrectly.
• Keep fingers behind the finger guards on the probes.
• Remove all probes, test leads, and accessories that
are not necessary for the measurement.
• Only use probes, test leads, and accessories that
have the same measurement category, voltage, and
amperage ratings as the Product.

• Connect the common test lead before the live test
lead and remove the live test lead before the common
test lead.
• Use only current probes, test leads, and adapters
supplied with the Product.
• Do not touch the probes to a voltage source when the
test leads are connected to the current terminals.
• Use only cables with correct voltage ratings.
• Do not use test leads if they are damaged. Examine
the test leads for damaged insulation, exposed metal,
or if the wear indicator shows. Check test lead
continuity.
• Examine the case before you use the Product. Look
for cracks or missing plastic. Carefully look at the
insulation around the terminals.
