• The battery door must be closed and locked before
you operate the Product.
• Use only cables with correct voltage ratings.
• Remove all probes, test leads, and accessories
before the battery door is opened.
• Replace the batteries 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.
• Measure a known voltage first to make sure that the
Product operates correctly.
• Use the correct terminals, function, and range for
measurements.
• 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 touch the probes to a voltage source when
the test leads are connected to the current terminals.
• Do not use test leads if they are damaged. Examine
the test leads for damaged insulation and measure a
known voltage.
• Do not use in CAT III or CAT IV environments without
the protective cap installed on test probe. The
protective cap decreases the exposed probe metal to
<4 mm. This decreases the possibility of arc flash
from short circuits.
