Safety Information

A Warning identifies conditions and procedures that are dangerous to the user. A Caution identifies conditions and procedures that could cause damage to the Product or the equipment under test.

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 the 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’s 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.
