Shortening the time interval is not possible.
An acoustic signal sounds when the adjusted time interval has expired.
The

This setting generally applies to all measurements with methods according to
analysis specification.

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 intervals, use the
Analysis timer
function (see section 4.5.9).
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

menu by entering a
time interval.
4.5.11 Measuring diluted samples
If the concentration of a test sample exceeds the measuring range of a meth-
od, you can dilute the sample by a factor 1 ... 99 so that the concentration of
the diluted test sample is within the measuring range of the method (see pho-
tometry analysis manual). Thus a valid measurement is possible.
After entering the factor for the dilution the meter converts the concentration
to that of the undiluted sample.
The display then indicates the measured value of the undiluted sample.
Entering the fac-
tor of the dilution
