7.8 Performance Test
BP4620
7-15

DC output voltage measurement accuracy test
Load: No load
Measurement connection: Measure the voltage of the output terminal of the BP4620 with a DC
voltmeter.
Settings: After setting initialization has been performed, set the output voltage limiters and
DC output voltage according to the following table.
Judgment: If the difference between the DC voltage measurement display value of the BP4620
and the value measured with the DC voltmeter falls within the rated ranges in the following table,
the operation is judged to be normal.


DC output current measurement accuracy test
Load: Short via a current shunt resistor
Measurement connection: Measure the detection voltage of the current shunt resistor with a DC
voltmeter and convert the measured value to a current value.
Settings: After setting initialization has been performed, set the operation mode and the DC
output current according to the following table.
Judgment: If the difference between the DC current measurement display value of the BP4620
and the current value measured with the DC voltmeter falls within the rated ranges in the
following table, the operation is judged to be normal.
