Advice needed for electric pedestal tester
I want to get a good tester to use before hooking up at a campground. Is there one that will check for the usual stuff like polarity, open ground, etc. - as well as tell the voltage? Thanks for ...

I recommend a monitor that will not allow power until all is correct and stable for about a minute.

The fact that it does not pass power for the first minute or two will get you the first couple of times you use it.
Both of these statements infer that the Progressive EMS unit is using this 136" time delay to analyze the input signal before deciding it's stable enough to pass along to the trailer. This is incorrect as the analysis takes no time at all - rather, delay is set at 136" in order to protect an A/C compressor, preventing it from restarting until head pressure has diminished to a safe level. Progressive EMS delay for the portable versions is fixed at 136" but delay for the hard wire versions can be shortened to a more convenient 15" by removing an internal jumper. I took this one step further with my own EMS-HW30C by wiring in an SPST switch in place of the jumper so I can simply switch between the two delay times, 15" or 136", rather than have to open the case and fool with the jumper. :B
