F- 18.0.0 CHECK TMP STABILITY
a) Call the Home screen. Referring to the Figure (right),
the TMP bar graph is populated with three horizontal
bars; yellow upper and lower alarm Limits (positioned
at 520 and below 0) and an 'actual' TMP bar which is
either red (with a TMP alarm) or green (no TMP alarm).
b) Press and release the 'RESET'' key and then
immediately press and hold it for three seconds. If the
"Adjusting TMP" message is present allow it to expire.
If a TMP alarm occurs attempt the RESET sequence
up to twice more then continue.
c) Watch the (green or red) 'actual' TMP bar. TMP is STABLE if (and ONLY if) it REMAINS between the 0
and 520 limits AND varies less than +/- 40 mmHg in two minutes. Proceed accordingly (three scenarios):
1) TMP is UNSTABLE: The 'actual' TMP bar rises ( ) towards the 520 Limit AND/OR falls ( )
towards the 0 Limit, greater than +/- 40 mmHg: See procedure number
2) TMP exceeds the 520 Limit (at some point) causing a "TMP Is High" alarm: See procedure
number F- 18.1.0
3) TMP is STABLE: See procedure number
