Multi 200 Instruction Manual
AC CURRENT
UNIVERSAL CLAMP TESTER
MODEL 200
INSTRUCTION MANUAL
1. INTRODUCTION
The model 200 universal clamp tester, using a universal current transducer,
is an innovative clamp tester which enables loaded cable searching and
load checking in the field—without having to separate cables into single wires.
The Model 200 enables selection of single-wire, single-phase, and
3-phase modes, and displays approximate values of load current.
The universal current transducer used in the Model 200 employs
a number of left-to-right symmetrical sensor coils, and is
constructed with shielding, thereby minimizing the influence of external noise.
The Model 200 also has a conventional current transducer, enabling
high-accuracy current measurements.
The model 200 is the world’s first instrument of its kind and will enjoy use in
a wide range of applications requiring current checking and searching for
loaded cable when laying cables and when working in close quarters.
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 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 to the maximum tolerable input.
● Never operate this instrument if it gets wet, damp or has any liquid condensation build-up on any
part of the instrument.
