Hi,

I am using a DT80 to log one analog 4-20 mA and two digital channels. I set the sampling frequency to 20 samples per second but I only get between two and four samples per second, randomly. Don't get why?

Does anyone have any tips on how to get faster sampling? If I read the data sheet the DT80 should handle up to 25 Hz sampling.

25Hz is maximum on one channel only. Need adjustment to switch, parameter and option like /k P11 P62 MD

So when you have speed you must have PC and USB stick not connected for performance better with adjustments. Your sampling I think can get 15 samples if /k P11=1000 P62=1 MD=5. Accuracy will be also less.
