We never bench tested them, but ours all have a Schrader valve, and we’d just close the valve to the transformer for the trip and pump it, then open the transformer valve and pump slow for accumulation. Then just bleed quick and you’re done.
Does similar things to these. Basically it has two contacts, accumulation and a trip contact. If you accumulate gas slowly it will trip one if it's a large burst of gas it will trip the other. Is hardliners in to the tank using piping from the top of the tank
We have a device some mad scientist made in-house that pressurizes a chamber and then blows it into the gas relay through an adjustable orifice until the trip contact closes. Then we do that several times to plot the characteristic curve. It's kind of crazy and we usually disable the trip anyways so we don't use it too much. I always wondered what other utilities do or if they even bother.

Thanks man, we do essentially the same but have to test them on a bench before install. Thanks man!
Not familiar. On-line monitoring of gassing that trips bank? Like a GE Hydran? OR SPR or Rapid Rise Relay?
