Below is a screen shot of the RMS-200 voltmeter overview page. This page shows at a
glance all voltmeter readings and provides a gateway for more voltmeter options. In the
screen shot below voltmeter 1 is displaying a positive reading of a 12v battery bank.
Voltmeter 2 is in ammeter mode, it is measuring the charge going into the battery bank
via a 50 millivolt / 50 amp current shunt (more on using shunts below). Voltmeter 3 is
measuring the output of a negative 24 volt power supply. Note: A green bar graph
indicates positive voltage, a red bar graph indicates negative voltage. To refresh the web
