indicated in the following table, the operation is judged to be normal.
Operation Mode Setting External Oscillator Frequency Rated Range
50 Hz 7.071 Arms or higher CC-EXT
500 Hz 7.071 Arms or higher
Harmonic distortion test using CV mode external signal input
Load: 6 Ω resistance load
Measurement connection: Connect the output of the external oscillator to the external signal
input of the BP4610. Then connect an AC voltmeter and distortion meter to the output
terminal of the BP4610, and measure the voltage and harmonic distortion.
Settings: After performing setting initialization, set the operation mode and external
oscillator frequency according to the following table. Set the output voltage of the external
oscillator to 1.2 Vp-p. Check that the output voltage of the BP4610 is 120
Vp-p.
Judgment: If the harmonic distortion of the output voltage of the BP4610 falls within the
rated ranges indicated in the following table, the operation is judged to be normal.
Operation Mode Setting External Oscillator Frequency Rated Range
10 Hz 1% or lower CV-EXT
10 kHz 1% or lower
Harmonic distortion test using CC mode external signal input
Load: 6 Ω resistance load
Measurement connection: Connect the output of the external oscillator to the external signal
input of the BP4610. Then connect an AC voltmeter and a distortion meter to the output
terminal of the BP4610, and measure the voltage and frequency distortion.
Settings: After performing setting initialization, set the operation mode and external
oscillator frequency according to the following table. Set the output voltage of the external
oscillator to 2 Vp-p. Check whether the output voltage of the BP4610 is 120 Vp-p (20 Ap-p).
If overload seems likely to occur, slightly lower the output voltage of the external oscillator.
Judgment: If the harmonic distortion of the output voltage of the BP4610 falls within the
rated ranges in the following table, the operation is judged to be normal.
Operation Mode Setting External Oscillator Frequency Rated Range
10 Hz 1% or less CC-EXT
10 kHz 1% or less
Output DC offset test during external input short
Load: 6 Ω resistance load
Measurement connection: Short the external input terminal (installation of a 50 Ω or 75 Ω
termination resistor is also possible). Measure the voltage of the output terminal of the
BP4610 with a DC voltmeter. In the case of the CC mode, convert the measured voltage value
into a current value by dividing it by the load resistance.
Settings: After performing setting initialization, set the operation mode according to the
following table.
Judgment: If the output voltage or output current of the BP4610 falls within the rated ranges
in the following table, the operation is judged to be normal.
Operation Mode Setting Rated Range
CV-EXT −0.1 to +0.1 V
CC-EXT −0.05 to +0.05 A
(−0.3 to +0.3 V @6 Ω load)
Residual noise test during external input short
Load: 6 Ω resistance load
Measurement connection: Short the external input terminal (installation of a 50 Ω or 75 Ω
termination resistor is also possible). Measure the voltage of the output terminal of the
BP4610 with a DC voltmeter. In the case of the CC mode, convert the measured voltage value
