Options Description
Store Off/On
With the Store On setting, all measurement data are stored automatically. With the Store Off
setting, no measurement data are stored.
Abs % Trans Switches to % transmittance or absorbance readings
Send Data icon Sends data to a printer, computer, or USB memory stick (Type A)
Timer icon
Functions as a stopwatch. 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 1, corresponding to no dilution.
Note: When a dilution is in effect, the dilution icon will appear on the display.
Note: If you are using undiluted samples, set the dilution factor to 1 again.
Chemical Form For some stored programs, an alternate chemical form and corresponding text can be selected.
