Hi Stuart Thank's for your help. What I realy need is the information that cannot be found in the user´s manual. For example : Scaling file extension : *.scl 1 scaling file for each channel (!) Now I can make proper measurements with PT-104. Before scaling the Resistance measurement error was 60 ppm...

I need to write a scaling file for my PT100 data logger (Pt-104) .
The type is table and unit is Ohm.
All four channels need to be scaled with different values.
The information contained in PicoLog User's Guide is unsufficient for this purpose.
Help please.
