CrocSeeCrocSee AC 80-260V 100A CRS-022B LCD Display Digital Current Voltage Power Energy Frequency Power Factor Multimeter Ammeter Voltmeter with 100A Split Core Current Transformer

I really like this display, I wish it didn't display 6 different things but it does so very nicely. Pretty easy to wire up it's a great way to monitor equipment that pulls heavy loads. I would rather have maybe 4 larger easier to see readings but otherwise no complaints.

I use this on the charger for my EV. It has been great. I purchased it October 2021 and the Amazon returns process won't work after 30 days (apparently).The fault is that I can no longer reset the kWh to zero which is annoying. The clear command remains on screen for less than 1 second whereas it used to remain long enough to execute the reset.I cannot find any contact details for Crocsee.Is there a master reset process or is the unit beyond recovery?I decided to buy another but it had the same fault that killed off the first one straight out of the box so I got a refund. It is a real shame as the unit when working is great and I now would like some more but am not going to keep buying, testing and returning until I get a good couple.

This nice little unit displays everything I want to know, voltage, current, watts, hertz, and power factor. And with the split core current transformer you don't need to cut the wire to install it, just open it, wrap around the wire and close it. I am using it to monitor the current being used by my well pump, but could be used for a variety of things, like air conditioner, furnace, fridge, freezer or any other major appliance. Another useful feature is that it displays accumulated watts, and will even keep the figure in the event of a power failure. I like it a lot. Only one caveat, you should be very careful installing this as you are working with 120-250 volts, and you need to shut off the breaker before doing anything, and also install a fuse (0.2 amps) on the line to the voltage part of the unit. Ideally, a certified electrician should do the install.

I'm using these meters to monitor the Grid Side of my Grid Tied solar system.They were very easy to connect up & are quite accurate.
