I have wired up a 4-20mA transducer to an easy e4 with an analogue module. I have checked the cable is ok but for some reason the scaled figures for the input which i have done in meters in a tank jump around quite a bit. Is there anything i can do about this. Cheers

hi,
[/size]which scale did you set up for your analog in ?
[/size]perhaps you should set your analog in 4-20mA to 4000-20000 ...
[/size]did you activate in the input setup to smooth the input 0-16 measured values


[/size]set your LS to output mm ...
[/size]and then calculate to meters

Hello srd,
the issue with the unstable measured values ​​has often been the topic here in the forum. Most of the time it was a grounding problem.
