4.5.8 Analysis timer
Measuring according to analysis specifications often means there are
waiting periods between the individual steps.
These waiting periods (time intervals) are stored in the instrument with
the program data for each program. The active Analysis timer function
automatically reminds you to observe these time intervals by means of
the menu guidance.
If you want to manually enter time intervals, use the Timer function (see
section 4.5.9).
The Analysis timer with the required time interval is automatically dis-
played at the due point.
Start the Analysis timer with the <START/ENTER> key.
It is not possible to shorten the time intervall.
An acoustic signal sounds when the adjusted time interval has expired.
The Analysis timer function is switched on or off in the Configuration /
Photometry/Analysis timer menu.
This setting generally applies to all measurements with methods ac-
cording to analysis specification.
4.5.9 Timer
When measuring according to analysis specifications, waiting periods
often have to be kept between individual steps of the method.
With the Timer function you manually set a time interval.
If you want to be automatically reminded of the given time interval, use
the Analysis timer function (see section 4.5.8).
The timer is displayed in the measured value display. It always displays
the remaining time of the adjusted time interval.
When the adjusted time interval has expired, the timer indicates
00:00:00 and an acoustic signal sounds.
The Timer function is started in the Configuration / Timer menu by en-
tering a time interval.
