(3) Open CT and clamp a target conductor wire. Close the clamp properly.
For AC load currents measurements;
clamp only the target conductor wire
For AC leakage current measurements;
clamp only the grounding conductor
For AC leakage current measurements;
*Not at grounding conductor;
for single-phase
two-wire system;
clamp 2-wires together
for single-phase three-wire
and three-phase three-wire systems;
clamp three wires all together.
***During measurements of large load currents, occasionally it has vibrating noises.
However, it does not cause any troubles or problems of its safety.
(4) Read the displayed value
(Each manual-range displays "OL" at 3300-counts or above. At 300A-range, LCD
displays “OL” at 300.0 or above. At auto
-range, it shifts to an upper-range 3000-counts
or above.) *Functioning the auto power-off, press "Power"
②
switch again to power-on.
