If the output voltage has exceeded 5V of setting voltage at 0 - 155V
range or has exceeded 10V of setting voltage at 0 - 310V range, the
Frequency display will indicate “OVP” and the alarm will sound.
Consequently, the
LED indicator will blink and the Voltage or Current displays will
show the overloaded voltage or current respectively.
If the Amplifier is fault or abnormal, or GBIT on the Amplifier is burned,
the Frequency display will indicate “A-SH” and the alarm will sound.
Volt Err
:
The amplifier will test first by itself after power on. If the test is failed, the displays
will indicate “Volt Err” and the alarm will sound. It can not only test if the instrument function
is normal and also can protect DUT to avoid it is damaged.
