The ER-500 has two power supply options The first power supply is an internal lithium 3 6V DC D size cell that powers
the monitor for about 6 years when no outputs are used The monitor can also derive power from a 4-20 mA current loop
(See
) If the current loop is used, a sensing circuit within the monitor detects the presence of the current loop and
automatically disconnects the battery from the circuit
