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 ...

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 - ..... snip
My question to Progressive:
Still curious on an intermittent error. If the voltage or ground briefly drops every 60 seconds does the EMS reset the timer at each error? Or does it connect at 136 seconds and wait for the next error before disconnect? Thank you
Today from Progressive:
If the voltage falls below 104 Vac for more than 6 seconds, the EMS will disconnect. A loss of ground will cause an instantaneous disconnect. When an error occurs and then the cause clears, the time delay starts. In your example, if the error occurs every sixty seconds, power would not be restored, because the delay would be resetting to zero each time.
My Comment: This is in effect monitoring of the connection for the entire 136 seconds. Power and connection must remain stable within specs for the entire delay timer or timer resets. I understand the effect is to have power off a minimum time for the air conditioner internal pressure to bleed down.
