Question: What is the digital display size? I wish the seller/distributor would include this information in the product description.
Document: 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!
Using these meters are more accurate than using some watt-meters because they don't all read the actual voltage. They are calibrated for a specific voltage and measure the amperage only to determine the wattage. I installed two meters in a extended depth 4"x4" double gang box and cut two 38mm x 68mm openings in a blank cover that fits a 4x4 gang box. I uploaded 4 images which can be seen under "Product Images from Customers".
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".
This is a great product. Well manufactured and seems very acurate, easy to read in daylight. Makes hand built projects look professional.
No directions in English or Spanish. Dont know how it works since I cant install it. Will keep you posted if I can get it working.
Determines current inductively, so you have to pass your AC mains through a ring pickup. I like this much better than a shunt resistor. Documentation consists only of labels, adequate if you know some electronics.
Lo he instalado y funciona perfecto.L&oacute;gicamente esto es para personas con conocimiento de electricidad.--I have installed it and it works perfect.Logically this is for people with knowledge of electricity.
It doesn't come with instructions, however there is a wiring diagram affixed to the back of the meter. If you don't have some basic understanding of electricity or know how to read a wiring diagram, then you shouldn't be installing this. I bought this to monitor my generator input power on both legs. My generator feeds the entire electrical panel, so now I can easily determine how much capacity I have left on my generator and balance the load. It's pretty accurate as well, I compared the measurement to my calibrated Fluke DMM.
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.
