IVR pulse at 4 volts gauges read low

nm9stheham said
The IVR voltage being 'low' is indeed consistent with the low gauge readings. It is more likely that the IVR is 'short cycling', i.e., the 12 pulses that it is putting out are too short and giving you a low average voltage. If your Fluke meter is not showing anything, then I really suspect the short cycling of the IVR. The Tripplite analog meter is showing all that it can....

Getting to the IVR in your case is a pain; otherwise there is an easy way to check with a 6V battery.

Thanks for the response!

Care to elaborate on the 12 pulses? I am seeing erratic timing in the pulses. The readings I took were at each sensor one at a time disconnected one at a time. All of them read the same pulse voltage and irregularity. I do have a o-scope as well somewhere, and can use it. The analog meter picked it up well.
