Safety Information
3
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 probes. The protective cap decreases the exposed probe
metal to <4 mm. This decreases the possibility of arc flash from short
circuits.
Caution
To prevent damage to the Product or the test equipment:
Disconnect the power and discharge all high voltage capacitors
before testing resistance, diodes, or continuity.
Use the proper terminals, switch setting, and range for the
measurement or sourcing applications.
