Specifications subject to change.
To ensure safe operation and service of the tester, follow these
instructions. Failure to observe these warnings can result in
severe injury or death.
• Before each use verify tester operation by measuring a known voltage.
• Never use the tester on a circuit with voltages that exceed the
category based rating of this tester.
• Do not use the tester during electrical storms or in wet weather.
• Do not use the tester or test leads if they appear to be damaged.
• Replacement test-leads should conform to EN 61010-031 and
be rated CAT IV 600V, 10A, or better. Do not use lower rated
test leads.
• Ensure tester leads are fully seated, and keep fingers behind
the finger guards and away from the metal probe contacts
when making measurements.
• Use caution when working with voltages above 25V AC RMS
or 60V DC. Such voltages pose a shock hazard.
• To avoid false readings that could lead to electric shock,
replace batteries when a low battery indicator appears.
• Always adhere to local and national safety codes. Use personal
protective equipment to prevent shock and arc blast injury
where hazardous live conductors are exposed.
• Tester is IP53 dust & water resistant. Following any contact
with water, thoroughly dry tester and test lead jacks prior to
subsequent use.
