3.2.1 Selecting an Output-Voltage Range
WARNING
The output voltage set using the output-voltage knob nearly doubles
when the output-voltage range is changed from 2.5 kV to 5.0 kV.
Conversely, if the range is changed from 5.0 kV to 2.5 kV, the output
voltage is reduced by approximately half. After changing the output-
voltage range, be sure to reset the output voltage using the output-
voltage knob.

NOTE
3.2.2 Key-lock Function
NOTE
In the READY state, change the output-voltage range (2.5 kV/5.0 kV) using the
Range Selection switch. When the output-voltage range is shifted, RANGE flickers.
This change is effective for the next test.
If you turn the output-voltage knob fully clockwise, the voltage may exceed the set
output-voltage range.
It inactivates all keys except the
START
key,
STOP
key, and the range switch.
The KEYLOCK lamp is lit while the key-lock function is active.
To switch to the KEYLOCK state, press the
LOCK
key. To cancel the key-lock
function, press the
LOCK
key in the Key-lock state while holding down the
SHIFT
key.
The output-voltage set using the output-voltage knob will not become invalid.
Even when the key-lock function is activated, the
START
and
STOP
keys on the
remote control box and the signals on the external I/O terminal remain active.
