INTRODUCTION
1-1 Unpacking and Inspection
Upon removing your new current transducer
from it's packing , you should have the following
items:
1. Current Transducer with coiled cable out put
plugs.
2. Instruction manual.
3. Carrying Case.
1-2 Front View
Refer to Figure 1 and the following numbered
steps to familiarize yourself with the transducer.
1. Transformer Jaws — Designed to pick up the
a.c. current following through the conductor.
2. Hand Guard — Designed to protect user for
safety.
3. Trigger — Press the lever to open the trans former jaws.

OPERATION
AC Current Measurement
1. Set the DMM at ACV Function and proper
range.
2. Connect the plug of transducer with DMM
firmly.
3. Press the trigger to open transformer jaws
and clamp one conductor only, making sure
that the jaw is firmly closed around the
conductor and reading the result from the
digital display of DMM.
MAINTENANCE
To keep the instrument clean , wipe the case
with a damp cloth and detergent , do not use
abrasives or solvents.
Any adjustment , maintenance and repair
shall be conducted by a service personnel.
