Review on 2-Piece Battery Meter Monitor: Low Voltage Buzzer Alarm, Digital Capacity Tester for 10-100V Batteries - Golf Cart Voltage & Temperature Monitor by Brian Delgado

Mine now gets stuck at #5 with no interface returning. Uhhh!. After downloading the instructions from the website it was set up. Use > to scroll from 1 to 5. When you reach the numbered page you want, press the power button to make changes, then hold before exiting the page. This saves input. Side 1. Battery changed to P48, Side 2 - OFF, Side 3 10.00 50.9, Side 4 - Off and Side 5 Power button pressed to calibrate. shows 20.0 and the current reading (which is currently 53.8 solar charges from my panels). I have yet to figure out how to get it back on the interface. Another post said it only showed 100% but scrolling and saving got me 97%. Be careful with tiny, tiny wires. If you need to disconnect, just pull on the white locking connector with the wires attached. DO NOT pull the wires or ask me how I know. UPDATE: Finally stopped waiting for menu item 5 to return to the interface. So I turned off the device and restarted it on the interface. At the moment this seems correct, but using menu items 1-5 doesn't get me back to the UI.
