1-5 Additional points to be noted for operation of HV amplifier
(1) Keep the length of output cable as short as possible.
(2) Keep the output cable away from floor, desks, or metal objects.
(3) Have no shielding on the output cable.
Due to the character of HV amplifier, the output cable of the unit is not shielded. If the
output cable has some stray capacity against ground (earth or metal object), output
voltage will be sinusoidal or step waveform and extra current will be drawn. As this
current draw parallel to load, the following appearance might be happened.
① Rated maximum voltage or current cannot be obtained.
② The waveform at constant current operation or current monitor is
distorted or changed

Load
When using this unit as a high speed and high voltage amplifier(except when
DC mode), make sure to have proper connection to make the stray capacity of
HV output line as low as possible.
