Parameters
All through the configuration-settings of the data logger, you will encounter parameters to setup your
logger. They are used on all ports (analog, digital, serial) and are generic in use. This section describes
the use and properties of parameters. Below a screenshot of some parameter-settings are shown.
Name
A appropriate name for the parameter (real life measurement).
Code
A short alphanumeric code to designate the parameter. This code will be used in the data files.
Unit
The unit of the real life parameter (i.e. meters)
Value factor
Multiplier to transform the electrical signal into a real life value. Default is 1. So, when the value factor is
2, all measurements are multiplied by 2. (in math: F(x) = ax+b, where a equals the value factor)
Value offset
Also to transform the electrical signal into a real life value, but now an addition (+) default = 0.
(in math: f(x) = ax+b, where b equals value offset) This is very convenient while using 4..20 mA sensor,
because they introduce an offset. (4 mA = 0 centimeter)
Decimals
The numeric precision of the value, displayed and stored on the SD card. (of course not the real-life
precision, only the numeric presentation)
Data log
Setting which enables the storage of the parameter to the SD card. When set to off it will be measured
and displayed, but NOT stored on th
e SD card. Default set to “ON”.
