40 V 2 V 3 V
400 V 20 V 30 V (< 100 kHz)
1000 V 50 V 50 V (< 10 kHz)
40 A 3 A (< 1 kHz) 3 A (< 1 kHz)
400 A 20 A (< 1 kHz) 20 A (< 1 kHz)

Duty cycle
Mode Range Accuracy of full scale
AC coupling 0.1 %~99.9 % 0.3 % per kHz + 0.3 %
Notes:
1. The accuracy for duty cycle is based on a 4 V square wave input to the DC 4 V range and maximum frequency up to 2 kHz. The duty cycle range can
be measured within 5 %~95 % as the signal frequency > 20 Hz.
