The PM6-LP-4C & PM6-LP-6C instruments are powered by a 2-wire 4-20mA loop. This loop will
either be supplied by an external power supply that also powers the
transducer or by power from a PLC etc. The PM6-LP-4C has a 4 digit LCD
display and the PM6-LP-6C is a 6 digit LCD indicator with ratemeter/totaliser functions.
Both models have remote input functions that can be programmed to functions
such as "Peak Hold".
