Safety Information
A Warning identifies conditions 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.
XWWarning
To prevent possible electrical shock, fire, or personal injury:
• Use the Product only as specified, or the protection
supplied by the Product can be compromised.
• The battery door must be closed and locked before you
operate the Product.
• Replace the batteries when the low battery indicator ()
shows to prevent incorrect measurements.
• Remove all probes, test leads, and accessories before the
battery door is opened.
• 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.
• 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 operate the Product with covers removed or the
case open. Hazardous voltage exposure is possible.
• Do not touch voltages >30 V ac rms, 42 V ac peak, or
60 V dc.
• Use the correct terminals, function, and range for
measurements.
• Do not work alone.
• Measure a known voltage first to make sure that the
Product operates correctly.
• Use only cables with correct voltage ratings.
• Use only current probes, test leads, and adapters supplied
with the Product.
• Do not exceed the Measurement Category (CAT) rating of
the lowest rated individual component of a Product, probe,
or accessory.
• Connect the common test lead before the live test lead and
remove the live test lead before the common test lead.
• Examine the case before you use the Product. Look for
cracks or missing plastic. Carefully look at the insulation
around the terminals.
