4.2 SET-UP & RUN MODES
For the SET-UP mode keyboard to operate, press the SET-UP/RUN button. The SET-UP light will come on when the
SET-UP mode has been entered.
SET-UP mode cannot be entered if the keyboard lock switch on the inside of the analyser is in the UP position. The
keyboard lock switch can be found on the door PCB (1630-2), on the lock side, at the top. If access is attempted while
the keyboard is locked, the message 'Illegal Access' will be displayed.
The temperature of a heated probe may fall if the set-up mode is used for more than 2 minutes.
While the analyser is in SET-UP mode the outputs will be frozen. Key functionality while in setup mode is indicated
on the keypad by the BLUE labels. If no buttons are pressed for 1 minute, the analyser will automatically revert to
RUN mode.
If an auto-calibration check is scheduled to occur while the analyser is in SET-UP mode, it will be delayed until the
analyser returnes to RUN mode.
To cancel an automatic calibration check cycle, press AUTO CAL button while in RUN mode.
