Product Description

By entering your model number, you can make sure that this fits.

The voltage measurement range on the DROK 7in1 digital multimeter is DC 0-33V, the current measurement range is 0-3A, the time measurement range is 0-99h59 minutes, and the capacity measurement range is 0-99. 999Ah, with a 0-999 energy measurement range. 99Wh

Short press the button to switch the data set; long press the button to clear the data to zero in the display interface.

The voltmeter ammeter uses a value of 0. 96'' OLED monitor with a compact parameter display and an easy-to-use interface

The voltage current meter panel is designed to work with a variety of power sources and is easy to set up.

Please make sure that all of your wires are connected properly and that you follow the wiring diagram to the letter.

Questions & Answers

What is the unit's idle current draw over a range of possible supply voltages (e.g., 12V to 24V)? , 4 volts, 12 volts, and 33 volts)? (doesn't have any load)?

It's around 14-years-old, as far as I recall. With two display units, 16 mA is drawn from a 5V source and outputs 12V. Despite the fact that the input voltage remains constant, the magnitude of the current varies.

Is it possible to use a lithium 12V battery with this?

It will, in fact. However, at around 2 p.m., they stop reading. 5 volts.

What is the current draw of this device? How much current will it draw at 12 volts?

I have mine set up with a push button switch, so it's not always on, and I only use it to check the battery in the RV.

Is it possible to monitor this by connecting it directly to a 12v battery?

Yes, but only the supply and voltmeter wires should be connected to the 12 volt battery. The thin wires are the ones you're looking for. Only small currents are measured with the thick wires. Any load greater than 3A may cause the meter to malfunction.

The meter is very nice

5/5

Current flow through the ground leg is measured. To replace the sticking analog voltage meter in my bench 3amp power supply, I installed this. To fit it into the old meters' hole, I had to make an adapter filler plate. The only thing to keep in mind is that this meter measures current by lifting the ground leg and connecting it to a shunt. If you have a multiple voltage power supply with all common grounds, current may bypass this meter and go undetected if your circuit uses multiple voltages from this supply. All common digital current meters, as far as I can tell, measure current through the ground leg, so this one is no different. Aside from that, I like this meter, though the digit size could be a little larger.

Great product; it's a little small, but I don't think that's a valid complaint given the price

5/5

It does everything it says it does in terms of functionality, and it's fairly accurate, according to two different DMMs I tested it with. This (the 7-pin connector) was wired by me. 1 multimeter version) up to a 750mA battery charger, simply to give me feedback on what voltage and current the charger is putting out at any time. As a bonus, it also let I also like that the display can be powered by any voltage between 4 and 20 volts, which meant I could just grab a random wall wart from my big box of unused wall warts, strip the wire ends, and hook it up right away. There's no need to go looking for one with the exact voltage output you need. In the future, I'll most likely purchase more of these.
