4.2 Measurement Procedure

(1) Make sure that all preparations described in the previous section are
completed.
(2) Set up an object to be measured so that it can be used.
Never energize the object to be measured even when it is ready
to be used.
WARNING
(3) Place the object to be measured through the Rogowski Coil Sensor.
a) As illustrated in Figure 4.1, release free end of Rogowski Coil
from the joint hole.
b) Loop the Rogowski Coil around the conductor to be measured.
c) Insert the Rogowski Coil into the joint hole.
*: The insertion length of the coil is about 12 mm from the joint hole
end. Insert the coil until it clicks into place. It is impossible to
measure correctly in the state when the free end of the Rogowski
Coil is not inserted into the joint hole or in the half way state of
insertion.
・
Never energize an object to be measured
before attaching the Rogowski Coil of this
instrument to the object. It is dangerous to
apply power to the object to be measured
before the attachment.
