3.2 Power Meter Interface Features
PM103x optical power meters offer full functionality to process signal from compatible photodi-
ode or pyroelectric sensors to be displayed and analyzed on a connected PC.
PM103x general features
· All PM103x models have a non-volatile memory which prevents power meter settings from
being lost upon shutting down or rebooting.
· A fast readout rate of 100 kS/s permits online signal monitoring.
· Finely graduated power and energy ranges permit optimal resolution for power measure-
ments.
· A Reset Button allows quick rebooting of the micro controller.
· The PM103x is powered either via the USB interface or via the DA-15 interface. The status
LED indicates appropriate connection to a power supply. It turns yellow when the PM103x is
connected to the PC or green after connecting to an external power supply.
· All PM103x can calibrate up to sensors with the help of the OPM software. Please see the
software manual for more information.
· Different electrical interfaces in PM103x models for integration into different systems in indus-
trial and scientific applications. The different electrical interfaces come with further func-
tions , described in the following chapters.
