Instruction for options:
■
High voltage output terminal on the rear panel (Optional)
On the rear panel, there is an optional high voltage output which is used for high
voltage output of scanner.
！
WARNING: The instrument applies 5kV AC/DC high voltage, so do not touch
the DUT and test line, or it will cause the danger of electric shock.
Safety measures should be taken around DUT to assure the operator’s safety.
Otherwise, please be careful about the outputted high voltage and avoid incorrect
connection and operation.
■
Remote control box
Customers can use this remote control to enable or disable the remote control.
It is connected to the PLC terminal on the rear panel, see PLC interface for more
information.
Functions:
INTERLOCK:
The interlock is used for the connection of multiple devices or used with the
device interlock. It prevents the simultaneous damage to the outputs of all
devices resulting from maloperation. When it is disabled, the high voltage
operation will be disabled forcibly.
START:
It is used to start the test. Only when INTERLOCK is enabled and stays in the
test status, it is usable.
STOP:
It is used to cut off the output voltage and to cancel the fail status. Its functions
are the same as that of STOP in the front panel.
■
HV scanner
ST9121 high voltage scanner can allocate many test points of the instrument
and provide the test voltage.
One high voltage scanner is equipped with eight channels and one channel for
one output. Different electric potential (HIGH, LOW, OPEN) can be set at each
channel. AC/DC high-voltage insulation test and insulation resistance tests can
be made in any one of the eight test points.
