propane regulator pressure question

I bought a new propane fridge for the cottage and put the older one in the shed. Found a regulator in the drawer and tested with my home built manometer, it tested 13" water column with the manometer connected straight to the regulator. I connected the fridge anyway and it seemed fine. I didn't like the idea of it being at 13" and it's not adjustable so I bought a brand new one which is adjustable.
Funny thing is, I tested the new one the same way and it too measures 13" wc??? Should these regulators not measure 11" when connected straight to the manometer??

Tks for responding, anyone else tried this test with a home made manometer?

    That does make sense when you think about it. I'll try and test the pressure with the fridge running, waiting a few minutes for it to settle. I guess if I set it at 11", the number I get without a load is irrelevant.
    Tks, maybe others will chime in with some input.

    I use a home made manometer to do an annual test of the propane system on our MH. I connect the manometer to the line that feeds the refrigerator and then run the water heater, furnace and stove to make sure the regulator supplies the 11" water column minimum pressure under load. With the loads off, the pressure is higher, but I don't remember a number. Pretty sure it is normal to have a higher outlet pressure on a regulator when there is no gas flow.
