Information

•
Do not apply more than the rated voltage, between the terminals or between each terminal and earth
ground.
•
Remove all probes, test leads, and accessories that are not necessary for the measurement.
•
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.
•
Do not work alone.
•
Measure a known voltage first to make sure that the Product operates correctly.
•
Replace the batteries when the low battery indicator shows to prevent incorrect measurements.
•
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.
•
Remove all probes, test leads, and accessories before the battery door is opened.
•
The battery door must be closed and locked before you operate the Product.
•
Do not use the Product if it operates incorrectly.
•
Disable the Product if it is damaged.
•
Use the Product only as specified, or the protection supplied by the Product can be compromised.

Caution
Do not use the Auto Volts function to measure voltages in circuits that could be damaged by this function’s low
input impedance (
≈
3 k
Ω
) (110 PLUS only).
