7.7 Operation Inspection
BP4610 7-8
Check during CV mode external signal input operation
After setting initialization has been performed, set the operation mode to CV-EXT.
Connect the output of the external oscillator to the external signal input of the BP4610.
Connect the output of the external oscillator and the voltage monitor output to an oscilloscope
and observe them.
In this state, try changing the output amplitude and frequency of the external oscillator and
check whether the BP4610 functions normally. The amplitudes of the external oscillator
output and voltage monitor output should be almost the same up to approximately 10 kHz.
Check during CC mode external signal input operation
After performing setting initialization, set the operation mode to CC-EXT.
Connect the output of the external oscillator to the external signal input of the BP4610.
Connect the external oscillator output and the current monitor output to the oscilloscope and
observe them.
In this state, try changing the external oscillator output amplitude and frequency and check
whether the BP4610 functions normally. The amplitudes of the external oscillator output and
the current monitor output should be almost the same up to approximately 2 kHz.
Check during CV mode adjusted characteristics operation
Lift the operation panel and turn all three response calibrator knobs counterclockwise all the
way.
After performing setting initialization, switch on the response calibrator, the AC voltage to
100 Vp-p, the frequency to 10000 Hz, and the waveform to square wave.
Connect the voltage monitor output to the oscilloscope and observe it. (The voltage 1/100th
the output voltage is monitored.)
In this state, turn all the knobs of the response calibrator and check whether the rise and fall
characteristics of the square wave change. The degree of change varies according to the knobs.
Once the check has been completed, turn all three knobs of the response calibrator
counterclockwise all the way, and switch off the response calibrator.
Check during CC mode adjusted characteristics operation
Lift the operation panel and turn the three response calibrator knobs counterclockwise all the
way.
After performing setting initialization, switch on the response calibrator and set the AC
current to 10 Ap-p, the frequency to 10000 Hz, and the waveform to square wave.
Connect the current monitor output to the oscilloscope and observe it. (The voltage (V) of
1/10th the actual output current (A) is observed.)
In this state, try changing the three response calibrator knobs and check whether the rise and
fall characteristics of the square wave change. The degree of change varies according to the
knobs.
Once the check has been completed, turn all three knobs of the response calibrator
counterclockwise all the way, and switch off the response calibrator.
