AC CURRENT TRANSDUCER
A
OPERATOR’S MANUAL
1. SAFETY INFORMATION
The AC current transducer has been
design-ed according to IEC -1010 concerning
safety requirements for hand - held current
clamps for electrical measurement and test.
Follow all introduction and operating
require-ments to insure that the current
clamp is used safely and is kept in good
operating condition.
1.1 SYMBOLS
Important safety information,
refer to the operating manual.

4. PRECAUTION AND PREPARATIONS
FOR MEASUREMENT
4.1
Dot not apply the voltage to the output
plugs.
4.2
Do not use or store this instrument in a
high temperature or high humidity
environment and do not store the unit
indirect sunlight.
4.3
Do not measure current before the unit
is not combined with DMM.
4.4
If the instrument is used near noise
generating equipment, be aware that
output voltage may become unstable or
get more errors.
5
This instrument must not be used
on
uninsulated conductors at a voltage
greater than 250V ac rms. or 250V
dc
5. AC CURRENT MEASUREMENT
5.1
Set the DMM at ACV function and a
relevant range.
5.2
Connect the plug of transducer with a
DMM and combined firmly.
5.3
Press the trigger to open transformer
jaws and clamp one conductor only,
making sure that the jaws is firmly
closed around the conductor, then read
the reading from the digital display of
DMM.
6. 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.
