(A) WARNING: Never exceed rating (Watt = Voltage x Amperage). Permanent demage to sensor will occur
(B) The operational distance between DF-RW and welding gun (welding conductor or cable) can be 0 mm when the welding current is less than 16000 A
(C) Measuring standard target: Ø15.5 x Ø8 x 5T (Anisotropy rubber magnet)
(D) Sin wave / X , Y , Z 3 directions / 3 times each direction / 11 ms each time
(E) Double amplitude 1.5 mm / 10 Hz - 55 Hz - 10 Hz (Sweep 1 min) / X, Y, Z 3 directions / 1 hour each time
(F) 1 = None / 2 = Short-circuit / 3 = Power Source Reverse polarity / 4 = Surge Suppression
