8-2 REC.
OUT
Output
This is a voltage output of leak rate during test. Connect the output signal to a strip chart
recorder to use it for recording of leak rate.
This output has two formats of 0 to 10 VDC (when linear display is set) and 0 to 8 VDC
(when log display is set) depending on the setting of the bar graph display selection mode on
the controller.
!
CAUTION
No short-circuit
Do not short the REC. OUT terminal (red) and the REC. OUT terminal
(black).
If shorted, the equipment may be damaged.
