Use threshold on analog channels to logic high/low??

Postby h3rman » Sun Jun 10, 2012 7:29 pm

Is there any way to use the input channels as digital on my PicoLog 1216? I have hooked up from +2,5V and in to the channels that i use, but because of interference & voltage drop the input is very hard to get a clean high or low.

Is it possible to use the equation function to have a threshold, for example if voltage is above 1V -> 1 or else 0 ?

Hi h3rman,

You may wish to try using the look-up table feature for the channel to map values to voltages rather than using an equation.

E.g.

Raw Scaled
0 0
999 0
1000 1
2500 1

Hope this helps,
