4.13 Measurement Function
The BP4620 has a function for measuring the output voltage and output current (DC value and P-P
value of each). Since the measured values are displayed in the LCD’s measurement value window, the
output status can be monitored.
The specifications of the measurement function are as follows.

DC output voltage measurement (Measures the AC+DC average. However, AC+DC
must be within

200 V.)
Full scale:

200 V (resolution: 0.1 V)
Measurement accuracy:

0.5 V (within DC

115 V, AC 0 V)

DC output current measurement (Measures AC+DC average. However, AC+DC must
be within

40 A.)
Full scale:

40 A (resolution: 0.01 A)
Measurement accuracy:

0.2 A (DC

20 A, AC 0 A)

AC output voltage measurement (Measures max. value of AC+DC

Min. value of
AC+DC. However, AC+DC must be within

200 V.)
Full scale: 400 Vp-p (resolution: 1 Vp-p)
Measurement accuracy:

2 Vp-p (DC 0 V, 120 Vp-p, 500 Hz)
Measurement frequency band: 10 kHz/

3 dB

AC output current measurement (Measures max. value of AC+DC

Min. value of
AC+DC. However, AC+DC must be within

40 A.)
Full scale: 80 Ap-p (resolution: 0.1 Ap-p)
Measurement accuracy:

2Ap-p (DC 0 A, 60 Ap-p, 500 Hz)
Measurement frequency band: 10 kHz/

3 dB
