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 it to a DIN rail.
: High-strength magnetic fields may change the output value: let avoid closenessWARNING
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, 60° with 6
turns, and so on.
