• Keep fingers behind the finger guards on the
probes.
• Only use probes, test leads, and accessories
that have the same measurement category,
voltage, and amperage ratings as the Product.
• Remove all probes, test leads, and
accessories before the battery door is
opened.
• Remove all probes, test leads, and
accessories that are not necessary for the
measurement.
• Do not exceed the Measurement Category
(CAT) rating of the lowest rated individual
component of a Product, probe, or accessory.
• Do not use test leads if they are damaged.
Examine the test leads for damaged
insulation and measure a known voltage.
• Do not use a current measurement as an
indication that a circuit is safe to touch. A
voltage measurement is necessary to know if
a circuit is hazardous.
• Do not use the Product if it is altered or
damaged.
• 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.
