Review: NOT made in the USA, runs off 240Vac just fine - The current most helpful review says "Made in USA" when clearly these meters are not, these meters are made in China. Also, they do not HAVE to run off of 120Vac, they will run off 80-260V. With those corrections out of the way, these meters work well. This meter helped me identify a serious problem with a 5-ton Trane heatpump unit. And no, it's not hard to stop a Trane, all you need is a faulty low pressure sensor switch and it will not only stop but also start running backwards in mere milliseconds. Be advised these meters alarm on Power only. I knew what they did when I bought them, I only wish they had a version that could be set to alarm on voltage or current or all three via independent settings. It would be nice if there was an audible alarm of some sort. I also wish they had a mounting box or panel with an appropriate cutout. (product improvement suggestions) Line voltage varies and so therefore current draw will also vary and therefore Power varies (voltage times current). In my scenario I have a 5-ton Trane heatpump unit whose compressor liked to run backwards. If your heatpump sounds louder than normal or hits like a sledge hammer while running, it's running backwards. Contrary to popular belief, running backwards did not harm the motor nor the scroll compressor that the motor drives (this unit is 11 years old). However, it does eat a lot of energy for no gain. This needleslly increases the electric bill considerably. It is also interesting that when running backwards, the compressor (I put the meter in the heatpump on the leads running into the compressor) draws more current and therefore has more power consumption. When running correctly, this compressor draws 16.6 Amps at 234.9V as measured. When running backwards it draws 21.9 Amps at 235.7V as measured. That is a 32.5% increase in current and therefore power for no gain (ie no heating or cooling inside the house = total wasted energy). Once I knew that, then I needed a permanent means with alarm and real time display inside the house. That's where these meters saved the day. It is also interesting to note that the impulse from forward to reverse draws a very short (milliseconds) 100 Amp spike. I was curious, so I recorded this with a data logger that I also got here from desertcart, namely the Supco LCV LOGiT Current and Voltage Data Logger (1s minimum data interval was sufficient to catch it twice out of 4 times), and I saw it instantly on an oscilloscope also bought here on desertcart, namely the Owon SSO8192. These power meters are great to give a real time, portable and inexpensive current, voltage and power reading but are not usefull for capturing fast spikes like the more expensive equipment. What was causing this reversal was a defective low pressure switch on the unit. This switch would let the 24V contactor coil voltage drop intermittantly, and for less than a millisecond. The resulting sound has a BANG loud enough to shake the 4,000 sqft house (through the vent system) followed immediately by a louder running compressor as it starts running backwards (like it was digging deeper). From forward to reverse in milliseconds with a 100A spike. BANG! By shorting the leads running to the low pressure switch, the unit now runs as normal, no idea what this has done to longevity. My theory as to why this Trane 5-ton scroll heatpump compressor draws more amps in reverse, is because the compressor must have an internal anti-backflow valve or device of some kind. With this meter I was able to temporarily monitor directly inside the outdoor unit and I can now permanently monitor the current draw from inside the house by connecting this meter to the breaker box lines running to the heatpump outside. I also have the alarm set to 5.3kW (240V times 22 Amps). The fans draw 4.7 Amps. 16.6+4.7=21.3A running correctly. In reverse that would be 22+4.7=26.7A. This way, I will have an exact alert if the heatpump ever tries to reverse again. No need for hearing accuity of the compressor. Note I wired this inside the breaker box, directly across the breaker feeding the heatpump unit with the current sense transformer on one of the wires. The permanent fix for the heatpump was to replace the low pressure switch (simply put a new one in line and abandoned the old). We also replaced the contactor as the contacts were severly damaged. I had the start capacitor and hard start unit replaced for piece of mind. I will leave this meter in place as I do not know if this same failure or another such as the high pressure switch will fail again in the future. I appreciate the peace of mind this meter with flashing screen alarm provides. Note, you can turn the LCD off by pressing the button and yes, on alarm it will still flash. It holds the LCD backlight setting (on or off) through a power outage AS WELL AS the power alarm setting. 2 minutes tested. It may hold these settings longer, I don't know. But for my purposes, that is more than long enough for the guardian 22kw to kick on and the transfer switch to automatically kick in during a power outage. For my purposes I don't care, but I also noted it did hold the kWh accumulation for two minutes as well. The leads on the CT transformers are relatively short (about 4-6 inches), I soldered on an additional 2 ft of tined multistrand 20 AWG silicone insulated (600V) wire to them. Solder station (Andolar 60W), solder (60/40 rosin core) and wire (Haerkn) were also bought right here on desertcart. I used electrical tape (3M Super 88) bought right here on desertcart to insulate the joints, you can use heat shrink tubing for a more professional look. At $15.30 apiece if you buy two, this is a very inexpensive troublshooting and monitoring tool. I hope this helps someone.
Review: Great units for generator current monitor - So far working well. There might me a SLIGHT discrepancy on values so not the most accurate devices, but close enough for government work. I like the design of the clamshell CT monitors. Great quality, bright enough to view in sunlight. They don't seem to consume much, but that might be the slight difference in values.. I wish they came with a gasket for installing on enclosures, but this worked very well for a DIY home generator monitor. Instructions are not the best, but AC supply is line and the other is the neutral. I used two of these to monitor each leg of the split single phase so one line was to red on one monitor, the other line went to black, and they shared the white neutral connections. I suggest using T connectors instead of splicing since the wire terminals are very small. You'll need something like a 24-18AWG but these are not provided.

## Features

- 1. Digital Multimeter:This power energy meter can measure and display voltage current active power energy frequency and power factor at the same time.with split current transformer,more convenient to install .
- 2. Overload Alarm function:Backlight and power will flash simultaneously to give an alarm when exceeding the preset value.You can preset power limit by yourself.
- 3. Automatic Data Storage Function:The last test data is stored automatically when the power supply abruptly lose. Don't worry about data loss due to sudden power outages.
- 4. One-touch Control:The button can be used to control the backlight,reset energy, preset power alarm limit.
- 5. LCD Display:Large-screen LCD with all sight 180° view,The blue backlight can be turned on/off manually. PZEM-022 requires an external power supply to light up the screen.

## Questions & Answers

**Q: Mostly to seller: is there a published communication module data description so we can write our own code to read the usb module output? or, an sdk?**
A: Note: amazon is showing this question on products that don't have Modbus.  PZEM-014/016 is the module you want for PC only interface, PZEM-022 for display only.

**Q: For 240v install/Monitoring, instead of running a hot and neutral (black and white) to the display, can I run both black legs from 240v (120v + 120v)?**
A: +1 what brycen says for United States 240V split phase service that uses 2 120V circuits. I clamped the coil over one of the hot legs and wired each hot leg to the load terminals on the meter. All measurements were accurate; amps, watts, volts, hertz, total power used, and power factor. I'm using this meter to monitor power supplied to a heating element for a brew kettle, which utilizes a Blichmann power controller to power the heating element. If you're using this for a similar purpose, wire the meter into the circuit BEFORE the power controller. Initially I wired it after the controller, which resulted in inaccurate readings..

**Q: does this work without having neutral wire? in many (old) houses in Saudi Arabia we use 2 x 110V = 220V, both live**
A: yes, I have one in the us on 240volts.  2 hot wires, one to the terminal marked hot and the other hot to the terminal marked neutral and it has been working for over a year so far.

**Q: Can this meter be powered by 120v ac and used to read 220v ac for an air conditioning compressor?**
A: As suggested, I bought two meters. Each is clamped over one leg of the power for the AC (120v+120v). I see current, volts and amps for each leg. Each meter is plugged into a standard 120v outlet. They are mounted in the garage on the wall opposite the breaker box (which is on the outside of the house.) Now I need a way to capture the information. I have an app that captures how often the AC blower fan comes on. I suppose if I get some averages of amperage used by the rest of the AC unit, under various outside temperatures, I can get a rough idea of how much power is being used.
