Factor of calibration - Range of values
To avoid a faulty calibration the factor of calibration is tested for plausibility at the
end of the calibration routine.
When the new factor of calibration is not considerable higher or lower (<factor 2)
than the previous factor of calibration the new factor will be accepted automati-
cally. When the new factor of calibration diverges stronger from the previous factor
the user can decide if he wants to accept it anyway (e.g. after changing the system
configuration) or not (e.g. because of maloperation).
When calibration is started via SPS or RS232 no testing for plausibility is occuring.
When calibrating internal it is also monitored if the newly calculated factor of cali-
bration is higher than 10 or lower than 0.1. In this case a warning (see W81 resp.
W82 in Chapter 5.2.) is displayed and the calibration will be interrupted.
3.14 Switching Off/Shutting Down
The PHOENIX L300i can be switched off any time by using the mains switch. The
turbo pump will be decelerated automatically. It is recommended to put the leak
detector into standby and vented mode. Approximately after 30 seconds the turbo
pump is decelerated sufficient to move the PHOENIX L300i.
