I'm doing a project to get one water pump running in case of power shortage. I'm using a bank with 3 x 12v batteries and an inverter to keep running this pump. I chose to use a couple of chip multimeter ($4.99) to monitor voltage of batteries and also the power line. Building a voltemeter with the ICL7106 plus an LCD display was more expensive and also more work. I also have a curent Sensor CSLA that can be used until 100 Amps with a sensitivity of 33 mV/A. I would like to use it to monitor the inverter consumption. In the same line of work(the lazy way) could it be possible to adapt one multimeter to display the Amps in in a scale of 0-100?. I mean convert in some way the voltage of the CSLA and display it in one of the multimeter scale in a way that , for instance, when the CSLA indicate 3.3V the display show 100.
