AC / DC CURRENT TRANSDUCER
1. Safety Information
The AC/DC current transducer has been designed
according to IEC-1010 and IEC1010-2-032 concerning
safety requirements for electrical measuring instruments
and hand-held current clamps with an over voltage
category (CAT II) and pollution 2.
Follow all introductions and operating requirements to
insure that AC/DC current transducer is used safely and
is kept in good operating condition.
1.1 Symbols
Important safety information,
refer to the operating manual.
Double insulation ( Protection
classII)
2. Description

Using this appliance in an environment
with a strong radiated radio-frequency
electromagnetic field (approximately
3V/m) may influence its measuring
accuracy. The measuring result can be
strongly deviating from the actual value.
5. DC Current Measurement
5.1
5.2
5.3
Set the AC/DC current transducer function
switch at desired A position.
Set a DMM at DCV function and a
relevant range.
Connect the output plug of AC/DC current
transducer with a DMM and combined
firmly.

5.6
Adjusting the DCA ZERO knob until the
DMM display show “0”, when does not
measurement before.
Press the trigger to open transformer jaws
and clamp one conductor only, making sure
that the jaws are firmly closed around the
conductor.
Read the reading on the LCD display of
DMM along with the polarity of the red
lead connection.
