Review on DROK Accuracy 0 33 00V 0 999 9MA 3 000A Voltmeter by Mark Deuschle

Despite the promised delivery time (weeks as far as I remember) mine arrived in 2 days. Having fixed my clunky initial setup, it works great to control the voltage and current going to the solar powered circulation pump for a solar water heater. The ammeter automatically selects one of 2 ranges (described in the product specifications) between 000.0-999.9mA (for current <1A) and 0.000-3.000A (for current >=1A); very versatile little package. We recommend that you copy the schemes in the descriptions of the images for further use when ordering; The device is delivered without documentation.
