MINI DIGITAL CLAMP-ON TESTER

MODEL 104

INSTRUCTION MANUAL

Thank you very much for selecting our digital AC clamp-on tester.
This model is complex instrument and employ a very reliable
mechanical/electronic design.
Before you use your new instrument, read this Instruction Manual
completely and familiarize yourself thoroughly with all functions.

satisfactory service.

1. FEATURES

● This tester is a clamp-on type leakage ammeter which represents the latest in current

transducer and digital technology and is the world’s smallest and most accurate

clamp-on type instrument of its type.

● Compact and lightweight.

● This tester is least affected by the external magnetic field.

2. CAUTION

● Before operating this instrument, familiarize yourself with all instructions outlined
in this manual.

● Always check to make sure that the function switch is set to the proper position.

● When making measurements, use CAUTION as dangerous voltages may be

present in normally safe areas.

● To avoid electrical shock, use CAUTION when working above 60V DC or 25V AC
rms.
Such voltages pose a shock hazard.

● Never make measurements with the battery cover OFF.

● Never fail to keep the maximum tolerable input.
