Timer icon
This functions as a stopwatch. It helps to ensure that the steps of an analysis are correctly timed
(e.g. reaction times, wait times, etc., can be exactly specified). When the specified time has
elapsed, an acoustic signal is emitted. The use of the timer has no influence on the measurement
program.

Dilution Factor Off/On
A corrective dilution factor can be entered in order to take account of certain properties.
The number entered at the dilution factor prompt will be multiplied by the result to compensate for
the adjustment. For example, if the sample has been diluted by a factor of 2, enter 2. The default
setting of the dilution factor is turned off.
Note: When a dilution is in effect, the dilution icon will appear on the display.
Note: If undiluted samples are used, set the dilution factor off.
Chemical Form
Some of the stored tests/methods allow to select the chemical form and the measuring range.
