True-rms Multimeters
Safety Information
3
• 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.
W 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 kΩ) (110 PLUS only).
