Hi Jasper have you had a look at the ADC11 terminal board instructions
http://www.picotech.com/document/pdf/ad ... ons-en.pdf
Section 2.2. gives a description on what you need to do measure current.
Also the PicLog Manual will give you an idea of how to set the unit up:
To give you a brief idea of how the softwre works, you initially create the settings, via File->New Settings. Once you have done that you create a data file to record the data to, via File->New data.
You may also be interested in using the scaling section when creating your settings, please have al look at section 188.8.131.52 Parameter scaling for more information.
Hope this helps.
