Hello,



I just received my slide potentiometer. Although I am a bit disappointed. I have ordered 6 overall, (different lenght). The Pot are



10kohm. The resistance reads good from 0 to the middle, but at the middle it shows almost 10K. after that it increases slightly. and as i continue to slowly push up the rail, in most of them they increase up to 11kohm , then go down to 10 and then back up again...weird Is this normal ? I doubt I received 6 deffective parts.

here is the model: EWAP1

I believe these are linear

** Groper alert.

** Shame they are all "audio taper."

The code letter A = audio taper.

The code letter B = linear taper.

It's an audio taper pot.

It's meant to be used as a *pot* not a rheostat.

Except for DIN standard pots ! It's the other way round.

Most do still use them as pots though.

Because it's not a linear taper. It makes more sense ( an audio taper ) when used as a pot. Unless you wanted a linear pot of course !

You need a linear taper. You must be careful when ordering POTS.

On rotary pots it was reverse log, but with a slide pot you can just mount it backwards. :-)
