NOTES

1. Please make sure the AC input is Pure Sine Wave.(Municipal electric power is pure sine wave). Please don't use the meter to measure AC power converterd from a DC-AC inverter UNLESS you can make sure the output from your DC-AC inverter is Pure Sine Wave. This is very importatnt.

2. This meter is used for single-phase power with one hot line and one neutral line. If you want to measure the circuit with 2 hot lines, you will need 2 meters, one for each line.

3. Applied load should not exceed the rated power.

4. Wiring order cannot be wrong.

5. This unit is suitable for indoor application only, do not use outdoors.

Feature
Waterproof Waterproof Fireproof

The meter can only measure the active power(real power). It doesn't show Apparent power. If you measure power from a DC-AC inverter, please make sure it's PURE SINE WAVE. Otherwise the meter can be burnt or melted.
6 in 1 Meter：The large clear screen can display voltage/ current/ active power/ cumulative energy/ frequency/ power factor at the same time.
Easy to Read: The backlight can be turned on/off manually, easy to read in the dark or in bright light.
Overload Alarm Feature: Backlight and power digits will flash when exceeding the preset power value.
One Button Control: The button is designed to control the backlight, reset energy data, or preset power alarm threshold.

Title: Works great, looks great
Review: 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.

Title: Nice little monitors! All the key circuit data you need, in one place.
Review: PROS: Good size/form factor. Great value if you D.I.Y. & can set up your own enclosure/project box/installation. Clear, legible screens, switchable (on/off) back light, all critical data to monitor circuits in one place, ideal for load management for emergency home backup generators, or similar applications, claimed internal overload protect circuit, monitor uses very low AC load, quality construction & look/feel. Data seems accurate when compared alongside digital multi meter. Back lighting & clarity of alpha-numeric characters is very clear & consistent: my photos do not do justice to the appearance of the screens to the naked eye. (They're nice). Very pleased, so far. Quality/longevity TBD.CONS: No UL listing, not for installations requiring NEC/home insurance approval (Such a capable monitor [with UL or other approvals] is not available anywhere @ this price point, however). No ground/earth circuit. Current Transformer wires could be a bit longer: as close as the CT’s were to my monitors, I still needed to extend all (4) of the CT leads with separately purchased wire. Accuracy is impacted if you exceed MFG max recommended wire length. Check w/ MFG, or search reviews - info is there. In typical USA residential applications (Single-phase, 2 x 120VAC ~ 240VAC), it is necessary to use (2) monitors to analyze the (2) 120v. lines coming into a typical service panel or load center panel. This requires you to do some basic math to combine the values from each monitor to assess Total system loads, etc. Not a big deal, but there seems to be a missed market in the USA for a single screen monitor with the capability to monitor (2) typical residential 120v. supply lines or "legs" on a residential utility service. Like I said, Very Happy - these are minor nit-picks/suggestions. Buy it - you'll be happy for the price!

Title: Cost effective purchase for the electrical readouts.
Review: The sensor was straight forward to install. I really liked the led back light with a button to turn on and off. Also liked the current core sensor can split and slide over to clamp on instead of having to remove the wire.Unfortunately, I wish the leads coming out of the sensor were longer. It’s a little strange to need 24V AC, but I hooked it up to the 24V transformer required to run the doorbell. Might need to purchase a 24V AC transformer for other specific applications. They pull so little current, I hooked them up to the same source.I bought two of these (one for each phase on my house) to see the independent loads. This will help once we have to use the generator to try to keep the loads balanced to obtain maximum life of the generator.All read outs and measurements seem accurate and the accumulation function works. I trust the other review comparing to a fluke device and that heavily impacted my purchase. Very happy.

Title: Nice meter for the price
Review: Using this to monitor output from a SSR that I control with a manual potentiometer. Works well and very readable display (see photo- taken in bright sun but shaded). It had gotten past me that this display isn’t rated below 80 volts. While reality is that it continues to work down to 58 volts AC current is still around 4 amps at that voltage and far more important to me than voltage so I’ll power the meter from input side of the SSR instead which will be useless for output voltage monitoring (not to mention wattage, PF) but will let me monitor current down to zero.The split current sensor doughnut is very convenient.I wish there was a little more room for managing wire impingement with the case cutout for mounting the meter because it is super tight wire clearance but I made it work without much extra effort.

Title: neat to see real time power consumption
Review: The split core makes it very simple to install. Used this in on one of the two 120V "hot" lines coming into the house (US residential 240/120 Volt, split phase = meaning two hot 120V come into the panel to the breakers +neutral+ground). Placed the CT around the 120V hot line and am powering it up from another breaker to make sure it gets 120V.Way it works1. the split core current transformer (CT) will measure whichever current of the conductor you place it around (single wire current flow ) - this is up to 100Amperes rated.2. You power it up by connecting to external power (specs are 80-260V)readings:current in Amperes comes directly from the CT.Voltage comes from the external power it is connected to.Power and energy come from combining the external voltage with the current reading (Watt=Current x Voltage) - thus the connecting diagram has it getting power from the same line your 'load' you want to measure to have accurate power readings.Can you measure a US split phase with one of these? No, you need two. One for each 120V line!Can you estimate with only one, yes! Just multiply your kWh Energy with 2. - Assuming a more or less balanced load panel - the one hot leg you measure gives you ~half of the breakers on the panel. You just need to multiply by 2 your total Energy for the other half of the breakers! (This also applies for double pole breakers in this configuration as the current is drawn between the two lines thus accurate reading. But it accounts for 120V from the external power instead of 240 - times 2 fixes the total energy also in this case)Anyway, always make sure you disconnect the power and play it safe when installing!

Review: 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.

Review: 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.
