This is an excellent product. The contents of the pages are well chosen, page 1 (photo 1) shows basic information, page 2 (photo 2) shows ALL information and page 3 (photo 3) shows the voltage and current curve. With the curve on display you can choose 4 time ranges by pressing the button for about 0.5 seconds: 5 minutes, 15 minutes, 60 minutes and 2 hours. This is a VERY USEFUL function, 2 hours will be sufficient for most loading tasks. Note that changing the time range will clear the graph (but not the cumulated data on page 2). The user manual describes a calibration process but it does not apply to this product. The no-load current is precisely 0.00000A (photo 4). Highly recommended!
