Calibrating Autometer gauges?

2242 is the sender the tech guy used as a reference when he said I was using the wrong one. I don't know what the part # is on the one I'm using now, I'd have to take it off and look.

Only other one I saw was the 2246 http://www.summitracing.com/parts/ATM-2246/ Totally different visually from the 2242.

If those are the only 2 choices, I have the 2242.
