Voltage alarm function (over voltage alarm threshold, backlight and voltage flashing to alarm). The reset function of energy key. Store data when power off. Large screen LCD (display voltage, current, active power and energy at the same time) Backlight function. Function Backlight control Press the key to turn on or off the backlight. The backlight state will be saved when power off. Reset energy Hold the key for 5 seconds until the number flashes, then release the key. Press the key again, then the energy value is cleared and exit the reset flashing state. If you don't want to clear, hold the key for 5 seconds again until the number doesn't flash, it means the energy value is not cleared and will exit the reset state. Voltage alarm Hold the key until the power display area displays "SET", release the key. The voltage area displays current high voltage alarm value, the current area displays current low voltage alarm value and the last digit begins to flash. Press the key to adjust the value. It will automatically switch the digit without operation over 3 seconds, then press the key to adjust the value too. Voltage alarm threshold set range: 6.5V~99.9V. After finishing the settings, hold the key until the screen displays "PASS". Wide Application This Digital DC Volt Amp Watt Energy Meter can be used to monitor the volt, amp, power and energy usage of battery, solar system, electric bicycle generator and other fields. It is suitable for indoor use and cannot be used outdoors. The load cannot exceed the rated voltage and current. Review: Worth paying the extra for. OK one has to wire up and mount display and shunt. - I made some ally U-brackets for the shunt and mounted using the supplied 8mm bolts. I put the display in a plastic box. These were mounted on a plywood base with two input and output connectors (choc block that could take max 16mm in my case). Yes you will need some 16mm (depend on your intended load) cable lengths and some hook up wire, the diagrams are clear. This is accurate, I checked against good quality test gear, spot on. The shunt ran cold, I bought the 100A version, it will never be used above 25A, this is a good factor of safety to aim for. Check the instructions, clear and easy to follow, like the diagram. It remembers the readings too, next time powered up can continue or easy reset. Highly recommended, aimed at somebody who has some experience in wiring and electronics. A remarkable price on desertcart. Review: Good value and it works - I bought the 100A + 100A/75mV shunt - Useful in helping prolong the life of my leisure batteries. Because I have a 95AH battery (total ~ 1100 watts), when the energy shows 600w after use following a full charge, I know I am around 50% discharged and can switch batteries. For those who don’t know, a cycle of 50% discharge followed by full charge is recommended to extend battery life. If, like me you can’t afford full Vitron kit then this is very useful to monitor battery usage. It measures energy consumed rather than load voltage as some do (some meters show a percentage battery consumption based on load voltage) so it can tell me when I’ve used 50% of my leisure battery. For those with solar kit, the energy used number won’t help much on its own if you are solar charging. You will see battery drain current and load volage which is still useful but because it doesn’t show current flowing into the battery only out and therefore it’s difficult to work out charge state. (You could use several units but I haven’t tried multiple units) Before I put this in my self-build motorhome, I thought I would test it as the shut resister looked bent. I have 2 leisure batteries; one a 95 Ah 12v wet acid by Bosch and one an import brand 110Ah AGM. I have a switch to connect 1 or 2 or both. The idea being that I charge them fully, reset the meter (hold down the button until it says reset) then use battery 1 on its own until energy reads 600w then switch to battery 2. As most our trips are off mains, short trips I suspect I am draining one battery too much by switching after 3 days as I do now. The picture shows my lab bench PSU throwing out 12.5v @ 3amp and is powering a 40w bulb. The shunt is connected to the negative terminal as it does in the van. My bench PSU is rounding the numbers to 1 decimal place and the Ketotek is showing a more accurate 2.98 amp. Not bad for a 100amp shunt resister. I left it running for many hours and the energy reading was also accurate. It doesn’t come with a surface mount box for the meter or the shunt but that’s ok because I am recessing mine. I also have a suitable box for the shunt resistor. I also like the LCD back light which is a single button press on/off. You can set voltage alarm which flashes the backlight so you could set it to 11.9 but I don’t think that would be much use. All in all, my view is that it is accurate and good value for money. ## Features - 【4 in 1 multimeter】 This digital DC ammeter voltmeter is used to measure the voltage, current, energy and active power of electrical devices. - 【Measuring range】 Voltage test range: DC 6.5~100V, current test range: 0~100A, active power test range: 0~10kW, energy test range: 0~9999kWh.

The "Chinglish" instructions are as follows. Step 1: Long press the key until the power display area display "clr", then release the key. Step 2: At this moment, the energy is flashing to prompt this is the energy reset state, if short press the key again, then the energy value is cleared and exit the reset flashing state. Step 3: If there is no operation within 5 seconds, it means the energy value is not cleared and will exit the reset state. Hope that this helps. **Q: Does it matter which way up the shunt goes. For instance, the writing on the side does it face up or down or does it not matter.** A: The shunt can be wired on the positive or negative feed wire, it's position does not matter, just cover the terminals with insulating tape or duct tape. Hope this helps. I have found it very useful for monitoring power usage from the battery. I use another meter with the shunt built in to monitor what my solar panel puts into my battery so the readings combined give me an accurate daily figure of how much battery power I have available. **Q: what is the voltage accuracy at around 25volts (counts)** A: I use this meter on a 12 volt caravan system linked in to a solar panel for charging the battery and a second unit fitted on the usage side, I have checked voltage displayed with a quality multi meter and both have showed the same readings, I'm very satisfied with the performance and accuracy of both units. I imagine that it should perform equally well on other voltages within it's operating rang as it is doing on my setup. **Q: How would this be wired in to a 12v system? Mine has arrived but without instructions it isn’t very clear?** A: Hello, please refer to the wiring diagram in our product description, or you can send message to us for the wiring diagram, thank you ## Customer Reviews ### ⭐⭐⭐⭐⭐ Worth paying the extra for.

It appears to work fine, although it only measures positive values. In other words you can only measure current flowing in one direction only (either flowing into or out of the battery not both). If you dont measure any current at first, reverse the sense wires on the shunt so that you measure the correct direction. I may buy another one and try wiring that into the shunt to measure energy used from the battery too! ## Frequently Bought Together - KETOTEK Ammeter Voltmeter Digital DC 6.5V~100V 100A Volt Amp Watt KWh Meter Gauge LCD Display Panel with Shunt, Current Voltage Power Energy Monitor Tester Multimeter - Kohree Master Switch Battery Disconnect Isolator Switch 12V-48V Battery Cut Off Switch, Master Switch Batterie, Master Power Cut-off Switch Kit, Car Battery Power Switch for Yacht Boat Truck Bus Car --- ## 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.ro/products/110420901-ketotek-ammeter-voltmeter-digital-dc-6-5v-100v-100a-volt](https://www.desertcart.ro/products/110420901-ketotek-ammeter-voltmeter-digital-dc-6-5v-100v-100a-volt) --- *Product available on Desertcart Romania* *Store origin: RO* *Last updated: 2026-07-05*
