MICTUNINGAC LCD Display Digital Multimeter Ammeter Voltmeter 80-260V 0-100A Current Voltage Power Energy Frequency Power Factor Meter with Split Core Current Transformer

I installed this meter in Feb of 2021 and as of this writing, it's been in continuous use for 8 months with no issues. We camp regularly and electric power isn't the same in every place we stay. We needed a visual meter to keep the electrical load at or below the output of whatever power source we were using. This meter fits the bill perfectly. Installation is fairly simple as long as you're comfortable working with 120V AC wiring. The load center in my camper is near the floor and I wanted to mount the display near eye level, so with some concern for impacting functionality, I added about 4' of wire to the induction coil lead. I wired up the meter and even with the extended induction lead, it works like a champ! I'm able to monitor in real-time, AC voltage, current in amps, power in watts (or kW since the meter is auto-ranging), total Energy use in kWh, frequency in HZ as well as Power Factor. Once you figure out how the lone button on the device works, you can easily reset the kWH field to monitor usage over a specific period of time. (To reset the kWh field, press and hold the button until the field with kWh is flashing, then release and press again to clear that field back to 0.)We regularly use this meter as an aid to power management in our 30A camper and it works great for that. Note that if you're using this to monitor usage in a 50A camper or to monitor a 240V circuit, you'll need two of these meters, one for each 120V leg.

I needed a generator to run our house when we have a power outage, which happens more now due to Southern California Edison turning our power off due to high winds. Been off 2 times this month alone, 24 hours and over 36 hours.The generator I bought is a 30 Amps at 3,600 Watts. There are no gauges on it other then fuel. I wanted to verify the voltage, frequency the generator is putting out plus the Amps I'm using. The Watts I'm not concerned about because the Amp breaker will pop before I reach the total Watts output of the generator. Knowing Power Factor will help you to understand this.I mounted the meter under my generator so I can check it anytime I want. I tested it against an expensive hand held meter a friend of mine has and the voltage and frequency readings were right on with each other..I was mainly concerned about the Amps. I tested using my table saw plus router running at the same time. Both devices showed I was using 12.5 Amps, within 200ths of each other.I'm very happy with the Mictuning meter. Even though it said not to use outdoors, my generator will only be outdoors a few time a year and will be under cover. No water should get onto it.The main thing I was looking for when shopping was the split ring that goes around the "hot" wire. I didn't want to have to cut the wire and splice it back together. The ring was easy to use, plus I put some electrical tape around it just to make sure it doesn't come apart. I really didn't think I had to, but I like to play it safe.Wiring was simple. I cut an old two prong extension cord and used the male end. The "hot" wire is the wire connected to the small prong. I screwed this wire into the second screw on the meter. The other wire I screwed into the first screw. The wires from the ring makes no difference which screw they are screwed into. I cut open the outside sleeve on an adapter I bought for this purpose and exposed the black wire. I put the ring around the black wire and used electrical tape to close.I have recommend this to a friend.

This is a easy solution to read the power from my Grid Tie solar system. It seems to be about 1 amp of ghost currents being measured, I assume that it is capacitance coupling. That said it is easy to read, back lighted and will keep track of the daily current that is made.

very poor instructions, (power goes in bottom of light bulb and ground is side of light bulb) ct goes on power line, regardless of what the drawing says.

The media could not be loaded. I have been wanting to put some power factor correction capacitors on my air conditioner to make it more efficient. I was lacking the equipment to get the information I needed, specifically the current power factor. This device in addition to the power factor gives you the voltage, amps, Kilowatts and frequency. I just measured my air conditioner and found out the power factor was point 69. It was also drawing 15.5 amps. I will be able to put some capacitors on there and raise the power factor up to somewhere around point 95, the current will go down which will save me money every summer from now on.It took 100uf on my 240v a/c compressor. Amperage went from 15.5A to 11.5A pf went from .69 to .98.Update:I also put a capacitor on my attic fan. The current went from 2.5 amps to 1.5 amps. Not a lot of reduction, but in my climate, my attic fan runs all day, every day, year anound.

Works as intended. Easy to setup but u must be comfortable working on your electrical panel (aka know what not to touch). Easy to read. I just take a picture to record date and energy usage then reset every few days/weeks, with time this should give a good overview of my total energy usage. First one worked well so I bought a second to monitor the other side of my panel.

I bought this to attach to an old 1972 SEARS 3K watt generator which I wasn't sure about the actual power output. Still working on the generator, but I tested both units I purchased and they both work great. The instruction manual was not the best but it was still very simple to wire with the diagram on the unit. I have only tested an energy efficient lamp with this and it came right within spec on the first try without any calibration. Really cool meter.

I basically bought this searching for a battery-powered multimeter. The store page currently describes this as battery-powered (false) and a multimeter (sort of true, but it's not a consumer product). This is really meant for someone like an electrician, amateur or otherwise, to install in their breaker panel.AC power is required, and needs you to run wires yourself--no plug is provided.Also, the directions are quite bad.
