 Safety Information
To prevent possible electrical shock, fire, or personal injury:
• 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 test leads if they are damaged. Examine the test leads for
damaged insulation, exposed metal, or if the wear indicator shows.
Check test lead continuity.
• Use only current probes, test leads, and adapters supplied with the
product.
• Measure a known voltage first to make sure that the product operates
correctly.
• Do not use and disable the product if it is damaged.
• Have an approved technician repair the product.
• 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 before the battery door
is opened.
• Do not operate the product with covers removed or the case open.
Hazardous voltage exposure is possible.
• Use caution when working with voltages above 30 V ac rms, 42 V ac
peak, or 60 V dc.
• Use only specified replacement fuses.
• Use the correct terminals, function, and range for measurements.
• Keep fingers behind the finger guards on the probes.
• Connect the common test lead before the live test lead and remove the
live test lead before the common test lead.
• Replace the batteries when the low battery indicator shows to prevent
incorrect measurements.
• Use only specified replacement parts.
• Do not use the tester in distribution systems with voltages higher than
550 V.
• Comply with local and national safety codes. Use personal protective
equipment (approved rubber gloves, face protection, and flame-
resistant clothes) to prevent shock and arc blast injury where
hazardous live conductors are exposed.
