Well, don't connect a battery or power supply to the 10A input again. You might have upset the power supply and/or the meter.
Let's go for a simple test. Put Black lead in "COM" and Red lead in "V ohm mA". Set the scale to 4V but any DC Volts range will do. Find a good AA or AAA battery - check it has power by testing in a torch or device. Then, touch the probes to the terminals at either end. Do you get either +ve or -ve somewhere around 1.4 Volts?
