Can this unit measure its own power supply voltage, or will I need an isolator?

This unit reads the voltage reading on the battery; no in-line devices necessary.

Maybe this will help I hook it up to a 1993 chevy truck I hook the voltage wire right to a ignition wire 12 volts in accessory and 12 volts with key on the same wire test with a test light to find the right wire. the voltage measures my battery voltage and when running my charging voltage no problems. I bought the three in one meter voltage temperature and time you can isolate each one or have them all read showing individual readings intermediately so yes it's can read its own power but it is powered by your cars battery I hope this helps you. Ps I'm a auto tech for 37 years now. I Had some problems with the temperature sensor probe but they sent me a new one seems to work okay now. Just so you know it comes in 1 gage not 3 that's just showing you what the gage dose.

No, this analyzer is for the mother board. I know of no way to check a power supply, they either work or they don.t. Hope this helps.

Power isn't as big a problem as the voltage drop. By the end of the strip, you may only be getting 10v, for example. You should measure it.

No. The meter must be powered by a voltage between 4.5 - 30 VDC. It will happily measure the 52 VDC source, but you will need either a voltage regulator or a separate power source (like a battery pack) to power the meter. If you use a battery pack to power it, you will need to connect the (-) terminal of the battery to the (-) connection of the voltage source you are measuring so that they will have a common ground.

It only shows runtime, load capacity and voltage. For watts you should look into a kill-a-watt device like this one: http://www.amazon.com/P3-P4400-Electricity-Usage-Monitor/dp/B00009MDBU I have one of those and it works great. Plug it in before the unit, then plug the unit into it and you will have the watt display of the whole ups.

Negative, yet there is an input receptacle with NO SPECS as to polarity and voltage needed, as well a missing current spec needed when multiple items are connected. Closer inspection of item shows no specs ON the item either, but it appears that an area below the receptacle has been sanded off, as if the specs were removed, as was the model info. Weird.. Inspection was done with lighted magnifier I used at NASA to inspect pins. sort of like owning a 7-stall barn that will only hold 4 horses at best ;-)

Yes, this is a voltmeter, so it will read whatever the voltage is at the time, it doesn't have any memory capability.

I have 2 units and have to issues with neither of them...I use it for basic AC and DC power reading takes. I do get some insignificant reading when power on but when connecting to the power source for measurement works well and power reading are correct.I hope this helps....

I can't answer the voltage comparability question, but yes, you will be able to set it up by yourself. The steps are simple and the directions are clear.

the power adapter that came with mine clearly states 120v input, does not appear to be auto ranging..

It powers from the power source you measure. It will come with wires to go to system positive and ground. But I really recommend you don't buy this product. I ordered two and they both gave different erratic readings for the 5 minutes they worked. Steer clear of this item.

If you are still interested. I recently purchased(1 month ago) a power supply tester from Amazon. Priced around $10.00 usd. It has connections for most if not all PSU's. as well as connections for HDD and floppy(3.5) Sorry but there is no name on the device for me to pass along. It might be worth while to do a search on Amazon for a PC power supply tester. It is about 3.0" long and 2.5' wide. It also has LED lights showing voltage amounts. Good Luck.

Yes, the unit requires a 110 outlet for the CPU board. The draw is minute about one - two amps.

Apu - I do not think so. The manual says to only use the original power supply and to only mount it indoors. I have mine mounted on the ceiling next to my garage door opener, so it is a bit inconvenient for me to check the output voltage from the transformer. I am not at all certain it is twelve volts. I believe it is more likely five volts. Someone who has mounted it closer to the button that opens the garage would be able to check more easily what the output voltage is (as indicated on the transformer).

No, it's 110 power supply. You would need to buy a universal converter or adapter for it.

There's no indication on the power supply or in the manual. I'd err on the side of caution and say its only 110.

It will read zero as long as the independent supply is enough to power the unit.
