I bought a
BSIDE ESR02Pro (
DTU-1701 V3.1 FW v
1.11k) a few days ago. However, in battery or 12 V mode, I can not calibrate (shorting of 3 terminals) it and can not get into the menu. Later, the display randomly lights up when I measure the capacitor. Before taking a new measurement, I always have to disconnect the instrument from the battery/socket for a while to get a new measurement after pressing the button.
Any advise what can be wrong? Where can I download the latest FW preferably from the author i.e. "?.??m".
