Mensurasoft-LZ is a very versatile software: he can make the measures on any type of measuring device, on the condition of having the good driver.
The drivers of measuring devices are those of  Mensurasoft system: dynamic libraries. The measures use function " cead ", and the drivers also must have functions "cnead", " ctitre " and " cdetail ".

Choice of the primary channel

In the menu Settings, take Settings ¦ primary device.
In the dialog-box, click the button " Chooser driver ", and choose the driver of your measuring device in the list, possibly in another sub-directory. Under Linux, drivers have the extension .so, and under Windows, they have the extension .dll.
After validation, if the chosen driver is correct, the white rectangle in the dialog box contains now one or some possible channels for measure. Choose the one who suits you, then validate. This validation closes the window, and makes that the measures of this main channel  are shown in the caption of the main window of Mensurasoft-LZ.

The button "Calibration" is usable only if the driver has a function calibration, what is not the general case.

The input line " Transformation function = f (xp, xa, xs) " allows to enter a function of transformation. By default, it is xP, that is there will be no transformation. If we want to multiply it by 1000, for example to convert volts in millivolts, it is necessary to type  xp/1000. 
Three variables can exist, xP which is the value received from the driver of the primary channel, xA which is from the driver of the auxiliary channel (if it is loaded and linked), and xS which is the value received from the driver of the supplementary channel.
We can use operators and functions described in the part "Transformation functions".

In the graphic windows, this primary channel  will be represented in red

Choice of auxiliary channel and supplementary channel


The principle is identical to the primary channel..
In the graphic windows, the auxiliary channel will be represented in green, and the supplementary channel will be represented in blue.
