HVA4321
3-10
ON/OFF
Indicates the output status of the internal high voltage DC power supply. When the high voltage DC
power supply gives high voltage output, the ON LED lights.
OUTPUT HI
It is the high voltage output terminal of the unit. Connect the accompanying special cable for use.
Output display warning lamp
When high voltage output is given, the LED around OUTPUT HI rotates and lights. The color is
yellow up to about 4.9 kV and red over this value. The rotation speed varies depending on the output
voltage level. The higher the voltage is, the faster the rotation speed is.
OUTPUT Lo TOTAL CURRENT
It is the return terminal of the high voltage output used in constant voltage mode or constant current
total mode.
OUTPUT Lo LOAD CURRENT
It is the return terminal of the high voltage output used in constant current load mode.
CURRENT SELECT
Total/load mode is set. When the unit is used in total mode, set it to TOTAL. When it is used in load
mode, set it to LOAD.
For details, refer to "4.2 Operation example in constant current mode (total)" and "4.3 Operation
example in constant current mode (load)".
