This scaling cannot accept floating point number, thus you will need to use workaround using two points scaling. For
example if you need to define 1 pulse as 0.1 mm for precipitation, because you can’t define 0.1 on “a” component thus
you can use this method:

Unit
Each measurement channel might have a defined unit, with which the data are recorded and presented.
Unit
field might
include up to 10 ASCII characters.
Precision
Precision
field allows to determine the precision of decimal points within measurement data either in the display or
transmitted data up to 4 digits (0, 0.1, 0.01, 0.001 and 0.0001). However the setting does not change the method of
saving numbers in the memory, data are always saved in the memory with maximum precision.
Notes:
This option does not influence the maximum amount of data saved in the memory.
Alarm
DT90 device allows to configure up to three event alarms. Alarms might be set for any channels, but not more than one
alarm per channel. In order to activate alarm on a given measurement channel, change field Deactivated at the bottom of
its window into the alarm number.
If an alarm is set on one channel, its configuration needs to be completed in
tab.
Global Sensor Settings
Analogs
This page allows user to set the type of input of 8 analog channels, either as voltage, current or PT100. These analog
channels are located on 4 connectors A1, A2, A3 and A4. This setting is required to set the logger for accepting the
signal.
