Figure 7-4 Warm-up phase, measuring mode, and input mode
Immediately following switching
-on, the ULTRAMAT 23 tests
the display elements. During this test, all elements light up
simultaneously for approx. five seconds.
The adjacent display subsequently appears with the remaining
warm
-up period which is counted down in seconds to 00:00
The analyzer initially carries out an AUTOCAL during the
warm
-up phase. The flow of AUTOCAL gas (nitrogen or air) is
displayed in the bottom line, and the remaining time is shown
in the line above this. This calibration cannot be
interrupted.
Following the calibration, the analyzer switches to purging with
sample gas. At the end of the purging phase, the analyzer
switches to measuring mo
de; however, full measuring accura-
cy is only reached after approx. 30 min if a further AUTOCAL
has been automatically carried out by the analyzer. The warm
-
up phase is then finished.
