P4400 'KILL-A-WATT' Meter

I have a P4400 KILL A WATT meter always plugged in here at my COMMS console at my house...

My meter is now reading high AC voltage of 136.4 VAC. It has been reading around 128 VAC here at the house and recently I have started seeing it creep up. I always thought that was high and using my FLUKE 77 work multimeter today I see the actual AC voltage is 118.2... I walked around the house 120V Receptacles and the AC Voltage using my FLUKE 77 meter all read around the 118VAC reading...

I am guess the calibration of the KILL A WATT has gone bad for me...

I made a couple of AC AMPS readings that agreed between the two meters so that part of the P4400 is working ok...

I see they only cost around $17 from AMAZON so guess I will order another one.

I did watch a VIDEO someone made troubleshooting a bad P4400 and he opened it all up and found a blown fuse. I did not see any calibration pots anywhere in the video...

Maybe I should get a different AC VOLTMETER to constantly monitor my 120VAC here in my comms room...

I have one these in POPUP trailer so i think I will order another for use in here...

    I monitor my usage to know that the devices I chose stay within the output of my solar system and under the radar of the battery bank.

    Thanks for comments - This has been my standard meter for a few years and then i started seeing the AC Voltage alitle higher and didn't give it much thought. Now it reads 134.6VAC... That caught my attention haha... I pulled out the second good multimeter and it reads 118.3VAC every here...

    I Think i will order a new KILL-A-METER brand meter since they only cost around $17 from AMAZON. I love the other functions it does... This is the meter I would use as well with my test setup for plugging into camp ground pedestals... so its not only just for the Ham Radio station here...

    If the the new one does the same thing then I will just give it up haha... I have now read the 118.2VAC from two different FLUKE meters so pretty sure they are somewhat correct... The 134.6 is down abit from my other reading a couple of days ago... The P4400 meter has been not plugged in since then... That is way to high a reading and I'm sure I would be seeing some local failures here...

    I'll replace it one time I reckon...
