13. Remote control
On the model

, a remote control is possible through
REMOTE
connector
⑤
on the
front panel,
REMOTE
terminal
or
REMOTE/OUT
connector
⑱
on the rear panel.
WARNING
When the tester is remote-controlled, high voltage is switched ON/OFF by
the external signal, so utmost care must be taken so that the high voltage
can no be erroneously generated and that no one never touches the output
terminals, high voltage cable or test sample, putting the first priority to safety.

When the plug of the remote control box is inserted, the
REMOTE
