1. FEATURES

● Extremely high accuracy AC/DC current measurements from 1mA to 10A without
breaking the circuit.

● MAX HOLD and MIN HOLD function provides the monitoring function for
maximum current measurements.

● Automatic zero adjustment function by micro computer for easy operation.

● The double shielding of CT provides minimum influence by the external magnetic

field interference.

2. SAFETY SUMMARY

The WARNINGs which appear on the following page must be followed to ensure
operator safety and to retain the good operating condition of the tester.

Safety Symbols :

△

!

Indicates the operator must refer to an explanation in this manual.

Indicates terminals at which dangerous voltage may exist.

△! WARNING

● To avoid electrical shock, exercise CAUTION when working with more than 60V

DC or 25V AC rms since the danger of electric shock may exist. In addition, check
that the test leads are in normal condition.

● POSSIBLE ELECTRICAL SHOCK. Do not make measurements if the case is
damaged or the battery cover is removed. Remove all electrical inputs before the
battery cover.

● POSSIBLE ELECTRICAL SHOCK or FIRE HAZARD. Do not expose this tester to
rain or moisture. Do not operate the tester in the presence of flammable gases or
fumes.

● Do not exceed the maximum input limits.

● Never clamp the conductor of the circuit carrying 300V or greater.

● Never make measurements for uninsulated conductors or bus bars.
