In the table the symbol corresponds to the switch in the ON position.
The instrument is factory delivered with range:
100A (T201DCH100-LP) or 300A (T201DCH300-LP), 800ms filter and RMS
mode.
Mounting
The device can be located in any position and place, in accordance with the
operating conditions above stated. Use the included holder bracket when fixing
to a DIN rail.
WARNING: High-strength magnetic fields may change the measured output value:
Let avoid closeness to permanent magnets, electromagnets or iron bulks that
cause such a modification of the surrounding magnetic field; try a different
arrangement or
orientation if zero error was greater than expected.
Multi-turn primary winding to improve sensibility
You can increase the sensibility of the device simply passing several times in
the hole with the measuring current, realizing turns with multiplicative
effect:
For example, passing 5 times in the hole, as to see 4 turns, choosing a 50 A
range, you get an equivalent sensibility of 10 A full-scale. When you make
this, let dispose the turns with symmetry in order to preserve accuracy: use
diametric contraposition with 2
turns, cross disposition with 4 turns, with 6 turns at 60° and so on.
Disposal of electrical & electronic equipment (applicable throughout the EU
