does this product store voltage reading for review at a later date or merely alarm / display power surge when it happens real time

No it does not store any data for future review. It displays only real time voltage information which is lost when disconnected to power source.

This is only a snapshot of current operating conditions and no data is retained.

HA! I asked them the same question! No.They said that the whole purpose of it was to monitor raw energy. a battery backup will give you inaccurate readings. that does make since, as this unit needs to read spikes and drops etc. as well as normal current pull.

As long as there is electricity running to it, it will register volt readings. It does not make any sounds if voltage drops below.

I agree. I see no evidence of this feature in the instructions. But there may be a capacitor in it that holds the settings even though it may be necessary to reset the current time when the power comes back on. Perhaps that is what they mean?

I don't know for certain but I would expect that would happen. If the power surge is large enough to disable/destroy other electronics in your house then I suspect it would damage this device as well.

This monitor doesn't have a voltage sensor (AC current is measured by inductive clamps and the voltage is entered manually on the display), so it can't compute power factor or adjust for phase mismatch. I haven't tried to check its accuracy, but other reviews I've seen have said that people find it to be reasonably accurate.

I think you have to activate the alarm for it to function. I did not activate the alarm. It is easy to tell when the power supply kicks in on battery power because of the increased hum from the inverter. There may be a bell that dings once when the inverter is active.

On the "Technology Research Website" they give some specs but the not the most important "clamping voltage" which I found through reading various sites. The joules rating is 510 but a low joules rating is not necessarily an indicator of an inferior product as wikipedia's reasonably good article discusses. Response time is usually very good for MOV types as I think this is since MOV is the least expensive design (wikipedia again:) Thats what I've learned so far. This product also looks more promising than the similarly priced & rated product that doesn't claim protection but only says "Surge Status Indicator" So I haven't decided to buy yet myself but hope the info helps others who are interested. P.S. I just called tech support at 800 780-4324 and was told the clamping voltage on this model is 700 volts. I have read that 400 or less is best on some sites about surge protection. The manuals for their other models show a lower clamping voltage and may be better.

Sure. My favorite feature of the protector is that if it is compromised by a surge, it will start beeping about every 30 seconds to inform you if it is out of sight. I would not use it for electronics because it is designed to continue providing power to your refrigerator so your food will not spoil and in the event of a storm, it would not continue any additional protection and would let additional surges through.

Hello Kelly, From my experience it saves your settings. I think you can think of the memory in this more like a flash drive. when not powered it still keeps the info. it does not have a battery inside, but i dont think it needs one. it is also part of your alarm system and would be using the juice from its battery in case of a power outage. hope this helps

I know this won't be helpful, but if it monitors power usage and finds nothing is in use, maybe it does. Even when it's plugged in the surge protector uses power. Unplug everything and see if it powers down.

When power goes out the thermostat holds the stored information for a while. If the power is out for extended time period then information is lost. This is as accurate as I can offer it as I've never timed it.

Yes it will test for power as well as continuity just make certain to read the directions to confirm the color and sound that goes with each.

I have had several brief power outings at my house and I have not had to reload the settings. You can save a config file to your computer in case you need to restore it to make it easy.

Mine read just at 12V when received so I didn't charge any more before installing in alarm system. It is working fine.

It does not record voltage changes. Also there is no audiable notification.

Apparently from the other answers it looses correct time after a while (4 hours?), but keeps the settings (probably a small flash mem chip on board).My feeling is that it would just be one more clock to reset after a power outtage....Coffee Maker, Microwave, Oven, Bedside Alarm Clocks,Clock Radios, Etc.So it does not concern me.All I have to do is remember! :-)
