COMPLIANCE
IP54
IEC61010-2-032: 2002 Compliant
IEC 61326-1: 2013
600V CAT IV, Pollution Category 2
For Class A Equipment
*In a high interference environment the accuracy of the
sensor may be degraded. If interference is suspected use
a standard Current Clamp. At conducted frequencies
45-50 MHz transients may be induced in the current
readings.
OPERATING CONTROLS
Power ON: The CT will power up as soon as it
is attached the power quality analyzer. The
LED will first flash the internal firmware revision
code of the CT. Then the range the CT is set to
will flash.
OPERATING INSTRUCTIONS
Installation
GPersonal protective equipment
(PPE) must be used during the
installation and removal of this
instrument.
1. Connect the CT to the Power Quality
Instrument. CT will power up.
2. Depress the clips on the flexible coil
contacts to open the flexible coil.
3. Place the flexible coil around the cable or
buss bar to be measured and close the coil
by clipping together the contacts.
NOTE Be sure the arrow on the CT is
facing the direction of the load.
4. Select the desired
range by pressing
the range button
repeatedly, until the
desired range LED
flashes.
NOTE: The unit will power up in the range
that was selected when powered
off.
Removal
1. Depress the clips on the flexible coil
contacts to open the flexible coil.
2. Remove the flexible coil from the cable or
buss bar and close the coil by clipping
