VOLTAGE (kV)
The limit value of the output voltage can be set in the range from
±
5 kV to
±
10 kV at the resolution
of 1 kV. For example, when the limit values of +8 kV for positive side and -6 kV for negative side are
satisfactory, make settings to +8 kV and -6 kV. Set the value with a flat tip screwdriver.
When MAX is set, the limit is invalid. The amplifier can give the maximum voltage output available.
In constant voltage mode
In constant voltage mode, the voltage of the internal high voltage DC power supply is limited and the
amplitude of the input signal is limited to limit the output voltage.
Use the unit paying attention to the following:
・ The limit voltage for setting is only a guideline. There is approx. 0 to 100V error for the set value.
・ If the output voltage is not proportional to the input voltage due to load, the value may be larger by
about 1 kV than the set value.
