I wanted to mention a few things that might be useful to potential buyers. 1. Expanding on the instructions of how to reset the total energy to zero The instructions say to hold the button down for 5 seconds until the energy value flashes and then release the button and tap it once again. That's the correct procedure, but what might be confusing is that there's an intermediate event that's not mentioned. When you press and hold the button, after 3 seconds the main display disappears and the words SET CLr appear. Since the energy numbers didn't start blinking but instead the screen with the energy numbers just disappeared from view you might be tempted to release the button. But don't do that! Instead keep holding the button for another couple of seconds and the main screen will reappear with the energy numbers flashing. ONLY THEN can you release the button and tap it once more to zero the energy value. 2. Understanding the precision of the energy numbers Note: In what follows I'm using the term "precision" to indicate the precision of what can be displayed, not reproducibility of repeated measurements. Because the energy display has only one fixed position for the decimal point - to the right of the leftmost digit - there are some limitations on the precision that can be displayed in different energy ranges, particularly above 10 kWh. I've attached some photos to illustrate this. The device has an energy resolution of 1 watt-hour (Wh). It won't display, for example, 0.5 Wh. A photo shows a display of 002 Wh. Many people will want to look at energy use above 100 Wh, and at that point the device begins displaying three significant digits. A photo shows a display of 132 Wh and another at 896 Wh. The measurement uncertainty in this range is 1 Wh. For example in the 132-Wh photo we know the energy is at least 132 Wh but less than 133 Wh. At 100 Wh this would represent a 1% uncertainty and it would be a 0.1% uncertainty at 999 Wh, just before the display mode changes. Above 999 Wh the decimal point appears and the display units change to kilowatt-hours (kWh). There are still three significant digits because the energy is displayed with two decimal places. Photos show 1.23 and 9.52 kWh. Just as in the previous display mode, the uncertainty beyond the last digit represents 1% at 1.00 kWh and 0.1% at 9.99 kWh. But at 10 kWh the fixed-position decimal point comes into play and things change. Because there is no position for a decimal point between the second and third digits the display can't show 10.0 but instead has to show 010, which is shown in a photo. This means that we know the energy is at least 10 kWh and less than 11 kWh. This 1 kWh uncertainty represents 10% at 10 kWh - far higher than the precision associated with measurements up to now. Obviously this 1 kWh uncertainty will become less important at higher energy ranges, representing 1% at 100 kWh and 0.1% at 999 kWh, the maximum energy that can be displayed. But it may be to much for some users wanting precise energy measurements closer to 10 kWh. To summarize, in the energy range from 100 watt-hours to 10 kilowatt-hours the device can display energy with a precision no worse than 1% and as good as 0.1%, which may be perfectly adequate for most users. Users who want to make careful measurements in the 10-30-kWh range - which may include PHEV owners and those partially recharging EV's - need to be sure that they understand what the display is capable of in this range. 3. Exceptional customer-service experience I bought two of these units in April, 2022. After making the measurements I needed I put them aside. In January 2025 I need to make some further measurements but had problems reliably resetting the energy to zero (which later turned out to be my own misunderstanding. See item 1.) I contacted CrocSee's customer service, hoping that they could tell me what I was doing wrong. Instead they offered to replace the units even though they had been out of their one-year warranty for almost two years! I very much appreciated this exceptional customer service, and I'm very happy with the product, which is meeting all my requirements. Review: Works Perfect and Very Accurate - For the money this is an absolute bargain. Very easy to wire up and works beautifully and is very accurate (verified with high end power analyzer). To get 6-readings simultaneously on the display is so very nice. CONTRARY to a lot of Q&A answers on this product I can absolutely verify this device works perfect with only one split-core current transformer (one unit) on North America 240VAC circuit measurements (using 2-Hot and no Nuetral). Even the supplier said it would not work, incorrect, it works fine you just can't use the Neutral line as then you would need two current transformers due to unequal legs. Check out my photos to prove it works fine on 240VAC with 2-hot legs, I'm measuring a garage heater in my photos on low and high heat settings. Excellent product and very highly recommended. ## Features - 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. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07K3S4K9L | | Batteries Included? | No | | Batteries Required? | No | | Best Sellers Rank | #205,436 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #156 in Voltage Testers | | Brand | CrocSee | | Color | Black | | Customer Reviews | 4.5 4.5 out of 5 stars (928) | | Date First Available | November 1, 2018 | | Is Discontinued By Manufacturer | No | | Item Package Quantity | 1 | | Item Weight | 5.6 ounces | | Item model number | CRS-022B | | Manufacturer | CrocSee | | Material | Plastic | | Measurement Type | Multimeter | | Min.

Works perfect this way.Now I can monitor normal power or generator power with just two meters. **Q: Does this record the amount of power used over a period of time?** A: It records watt-hours, but not time. If you want to know how much power was used over, say 30 days, you must manually note when you first began monitoring the circuit. This can be as simple as taking a picture of the display with your phone, which will of course time/date stamp your picture. One added benefit, it will retain watt-hours even if power is lost. It is not cleared until you manually clear it with the button to the right of the display. **Q: Does the meter display values up to the test values or main specifications? (ie. rated up to 100 amps, but displays only up to 5 amps)** A: (What are you connecting this too?) You’ll get what ever the AMP value from the watts divided by voltage. Watts / voltage = amps Im running 3500 watts at 240v = 14.5 amps (this is shown on my display) If you are only seeing 5 amps, then your wattage is only around 600w on 120v circuit. Hope this helps **Q: Has anyone found a solution to read these meters remotely (via Bluetooth or WiFi?** A: Set up a wifi camera, point it at the meter ;-). Without significant skill in micro-electronics there isn't any other way. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Resetting the energy to zero; precision of the energy display; a great customer-service experience *by E***R on March 6, 2025* This is an excellent product that I continue to be very happy with.

Excellent product and very highly recommended. ### ⭐⭐⭐⭐ Cost effective purchase for the electrical readouts. *by B***D on December 21, 2019* 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. ## Frequently Bought Together - CrocSee 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 - bayite DC 6.5-100V 0-100A LCD Display Digital Current Voltage Power Energy Meter Multimeter Ammeter Voltmeter with 100A Current Shunt - AC Current Voltage Amperage Power Energy Panel Meter LCD Digital Display Ammeter Voltmeter Multimeter with Split Core Current Transformer CT AC 80-260V 100A Multi-Function Power Monitor --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.id/products/90928398-ac-80-260v-100a-crs-022b-lcd-display-digital-current](https://www.desertcart.id/products/90928398-ac-80-260v-100a-crs-022b-lcd-display-digital-current) --- *Product available on Desertcart Indonesia* *Store origin: ID* *Last updated: 2026-04-23*
