The optocoupler module circuit board calls for a 100k trimpot and 1 M trimpot. How do I determine which is which?

Using my cheap radio shack multimeter with the dial set on 2M, one trimpot reads 1.025. Would that go on the 1M trimpot location?

The other trimpot reads 0.097. That go on the 100K trimpot location?

Look on the bottom of the trimpot. One says 105 (1M) one says 104 (100k)

Look on the bottom of the trimpot for some tiny little numbers (you might need a magnifying device to see 'em). IIRC, it should say 104 for 100K and 105 for 1M.

EDIT: Geez, Nick did it to me AGAIN! :evil: :wink:

I had this problem when I built mine, too. I ended up metering them to make sure.

Just to be clear....yes and yes.
