volts, then 2 volts is 50% of full scale. In this case the scale is from 0 to
4 volts and the input is 2 volts, then this is 1/2 of full scale.
The percentage of the input voltage is then compared to the thresholds
of Low Warning, High Warning, High and Low Critical that the user
has set. From this the status is then computed and emails, traps are sent
if necessary.
Jumpers
The DC Voltage sensor has a jumper to set the expected range of input
voltages. This can be set to 10, 20, 30, 40 or 60V. You should use the
lowest expected settings in order to achieve the maximum resolution.
