10.4.5.2 Executing Semi-Auto Indication Check
Semi-automatic indication check is started either from the display or by external
contacts. When started from the display, only the channel selected on the display is
checked. When started by an external contact, all working channels can be checked one
channel after another. Assuming that [Span-Zero-Third] is set to points on the Indication
check setup display, the procedure is described below.
When started from the display
1) From the basic panel display, touch the Setup key to display the [Execution/Setup].
Select [Indication check].
2) Select [Semi-auto ind. check]. The channel select display of Fig. 10.20 is displayed.
3) Select the channel to perform indication check. The screen of Fig. 10.21 is displayed.
4) When you select [Start ind. check] the [Semi-auto ind. chk] trend graph of Fig 10.22
is displayed, and Span indication check begins.
5) When the preset check time (same as calibration time) has elapsed, Span indication
check ends and Zero indication check begins. Likewise, when the preset check time
has elapsed, Zero indication check ends, and third gas check begins.
6) After check time (calibration time) ends, stabilization time begins. After the preset
stabilization time, the instrument reverts to measurement mode.
7) Touch the Reject key to abort indication check. If you abort Span or Zero or third gas
indication check then check time is skipped and stabilization time starts. If you touch
the Reject key again then stabilization time is also skipped.
