Rush current (INRUSH) 600.0 A (CM4371, CM4372)
Conditions of guaranteed accuracy: After zero adjustment has been performed
INRUSH trigger level: For 600.0 A range, detection of current of +10 A or more or -10 A or less
Coupling type: DC coupling
Crest factor: For the 600.0 A range (500.0 A or less), 3
For the 600.0 A range (greater than 500.0 A and less than or equal to
600.0 A), 2.5
Peak detection time width: 1 ms or more
