 Warning
To prevent possible electrical shock, fire, or personal injury:
•Carefully read all instructions.
•Read all safety information before you use the Product.
•Use the Product only as specified, or the protection supplied by the Product
can be compromised.
•Do not use the Product around explosive gas, vapor, or in damp or wet
environments.
•Do not use the Product if it is damaged.
•Disable the Product if it is damaged.
•Do not use the Product if it operates incorrectly.
•Examine the case before you use the Product. Look for cracks or missing
plastic. Carefully look at the insulation around the terminals.
•Use only correct measurement category (CAT), voltage, and amperage rated
probes, test leads, and adapters for the measurement.
•Measure a known voltage first to make sure that the Product operates
correctly.

•Do not use test leads if they are damaged. Examine the test leads for damaged
insulation and measure a known voltage.
•Do not apply more than the rated voltage, between the terminals or between
each terminal and earth ground.
•Do not use the HOLD function to measure unknown potentials. When HOLD is
turned on, the display does not change when a different potential is measured.
•Do not touch voltages >30 V ac rms, 42 V ac peak, or 60 V dc.
•Keep fingers behind the finger guards on the probes.
•Remove all probes, test leads, and accessories before the battery door is
opened.
•Do not exceed the Measurement Category (CAT) rating of the lowest rated
individual component of a Product, probe, or accessory.
•Remove the input signals before you clean the Product.
•Have an approved technician repair the Product.
•Remove the batteries if the Product is not used for an extended period of time,
or if stored in temperatures above 50 °C. If the batteries are not removed,
battery leakage can damage the Product.

•Replace the batteries when the low battery indicator shows to prevent
incorrect measurements.
•Use only specified replacement parts.
•Use only specified replacement fuses.
•Limit operation to the specified measurement category, voltage, or amperage
ratings.
•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. The protective cap decreases the exposed probe metal to <4 mm.
This decreases the possibility of arc flash from short circuits.
