(2) Description of signals
<Output signal>
-COM(ANALOG GND)
→
Common for open collector output
SET POINT L
→
Outputted when the leak rate measurement value
is higher than the setpoint L value. Outputted in
test state. This output is reset at the end of test.
SET POINT H
→
Outputted when the leak rate measurement value
is higher than the setpoint L value. Outputted in
test state. This output is reset at the end of test.
START UP OK
→
Outputted from the time when startup is normally
completed and standby status is set up. This
signal is outputted until stop action is started, but
if automatic sensitivity calibration is executed, the
signal will not be outputted for the time.
SYSTEM ERROR
→
Outputted if any trouble occurs. It is reset the
moment the error mode is reset by pressing .
(when the DIP switch signal output setting is
normal)
-0
→
Outputted when the leak rate measurement value
is minus (value smaller than zero). Outputted in
the test status.
