Accurate and good visibity

Second set of meters I've purchased. First set were used for a generator load bank test set. Worked out perfect. Large lighted readout and accuracy was perfect for my needs. Verified readings with my Fluke meter. Accurate enough. Second set are mounted on generator transfer panel. I used a common switch box and trimmed a cover plate for meters to fit snugly. Mounted to the bottom of the transfer panel. I can monitor generator voltage and loading from across room. Only minor complaint is the length of the wires on the c/t for amp metering. Only about 3" long. Inconvenient, not a deal breaker. Very pleased with the purchase.

Excellent as Generator Monitor

I recently deployed a new Wen 7KW inverter generator and I wanted to be able to monitor the load. These little guys are well suited to the job. Shown in the pic is right after I spooled it up and tied to the buss. Thus it is showing a pretty small load. As soon as I started cutting in systems they registered very accurately when compared to my amp clamp. Definitely worth repeating that these are not typical DIY items. If you don’t have a good working knowledge of electrical systems you could definitely do yourself harm or worse, burn down your house. Playing with line AC is no joke. Also as noted by others, you can calibrate them. I used a rig on my workbench powering a heat gun which pulls about 10 amps. Matched the Drok meters to what my amp clamp was telling me and they are now dead nuts. Simple! The only thing now is longevity. Hope they last! Hurricane season is here so there is a chance I’ll put this system to real time use (versus testing for an hour)

Nice product at a bargain price!!!

Last year, I bought several of these on Ebay, but they did not come with the snap-on plastic enclosure. This one does and that is an important new safety feature. This one still works just like those earlier units, but the new case makes it much easier and safer for mounting purposes. The one criticism I have is that the pair of wires on the current sensor (coil) are not nearly long enough for most applications. They should be AT LEAST 18" long. If too long for the application, just cut them to length and restrip. My application for this meter was to replace the cheap analog Voltmeter on the control panel of a portable gas generator. I hooked up the current sensor, so I can monitor the current drawn by either the 230V or one duplex pair of 120V outlets or two out of 3 at the same time. It was just too much extra work to connect all 3 at the same time using just one current sensor and meter. I connected the meter's digital voltmeter to the 240V outlet, but it reads the voltage correctly at either outlet depending on which position the generator's 120/240V switch is set to. In the 120V position it reads "120V". In the 240V postion it reads 240V. In the 240V position with only a load on either of the 120V outlets, it still reads 240V. Of course, this is essentially a false reading displayed on the meter. At least the load current is always displayed correctly (unless the "spare" 120V outlet is used). In any event, I have a L14-30p to 5-20Rx2 - commonly called a "splitter" - on order from Amaxon for optional use on my generator's 240V outlet. For 120V loads, I will just use the splitter plugged in to this outlet and then two 120V loads will display the combined load curent correctly, but the voltage meter will still be misleading since it still will display 240V. I will stick on a warning label on the front panel to warn the user that the "voltmeter" readout works this way, which is no different than the old analog voltage meter I replaced. Sorry, I digress . . . For this much functionality in such a compact littel meter (and so versatility in terms of model variations for measuring AC or DC power with different ranges) this product is being sold at a bargain price!

Inaccurate, but fixable.

This is a good product, but the claims about 1% accuracy are way too high for the ac current readings. Using a calibrated current meter to verify, I saw readings of 7.9 amps on one meter and 7.1 amps on a second one instead of the actual 7.07 amps present. Now the 7.1 amp reading is good considering the 0.1 amp resolution of this meter, but the 7.9 reading on the other meter is way too high and results in a 11.4% error. I swapped the CT's between the two meters and the readings went along with the CT's, not the meter. So that told me that one CT was wound with too many turns of wire or that the meter was not calibrated to match the CT; but fortunately the meter can be calibrated to match the CT with the error. There is a small potentiometer on the circuit board closest to the display and that can be accessed through a hole in the other (rear) circuit board with a tiny screwdriver (aka, tweeker). Just remove the rear part of the case and hook up the meter. If you know the correct reading that should appear, then adjust the potentiometer to match that reading. There is no access hole in the plastic rear case, but you could cut one if you find it necessary to adjust this in the installed condition. Now both of my meters agree with the calibrated instrument. I'm happy with them and hope they last on my ac generator panel. Edit a few hours later. The meters are installed on my generator. They work fine. Followup Oct 17, 2017: Used the generator during a week of power outage following Hurricane Irma. The meters worked perfectly outdoors, no issues.

great meter display - readable from a distance

These work very well; accuracy against an expensive RMS meter is generally within 1-2% when I tested. Replaced analog meters on the panel. Only problem I had was that I put two displays side-by-side in my service panel, (2 electrical services on the boat), and the back light was quite different on the second one. Amazon was very helpful in helping replace one so that the brightness was the same for both.

Great product

Great product, voltage is accurate at 122 volt . i used Fluke clamp meter with calibration certificate to compare the measurements. Fluke and Drok reads both 122V AC but Amps read lower around ~ 0.9A sometimes ~0.3A Fluke reads 9.9A while Drok reads 9A. Fluke reads 11.3A while Drok reads 11.0A. This Digital Voltage Current meter usually will be mounted with same level of person's eyes or above, but it is blurry when it mounted above 45 degrees of your eyes. thus this product should be mounted at your eyes level or lower to get best view, it is still ok if you mounted above your eyes level but not more than 45 degrees. - Since the wires of transformer are green, the transformer input should be (Green Terminal) not blue. The (measure voltage) is green which makes some electricians confused and easy to have error connections. I like this product and it great. I will update the review if any thing arises. Thank you for this product.

This is a top quality product that I recommend never had an issue with one of these yet

I've bought a few of these already for controllers I build. The difference between this and another one sold by another place is this once has the circuit board covered and the power supply has actual screw connectors. This is a top quality product that I recommend never had an issue with one of these yet.
