current when the power supply is turned on. The level of inrush current is several times
greater than normal input current. (The level of inrush current will differ depending upon
the timing when the power supply is turned on, and the impedance of the supply source.)
●
When performing a mega test (insulation test) on signal transmission cables, be sure to
remove the cables from the driver (transducer) and signal conditioner.
In addition, be sure to short-circuit the cables before reconnecting them after a mega test
to discharge any electrical charge.
Connecting cables with an electrical charge to the driver or signal conditioner could result
in damage to the product.
