PM103x Optical Power Meter Interfaces Chapter 4 Operating Instructions
4.2 Power Meter Interface Features
PM103x optical power meters offer full functionality to process signal from compatible photodiode 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 measurements.
· A Reset Button allows quick rebooting of the micro controller.
· The PM103 /A /U are powered via the USB interface. Additionally, PM103 can be powered via the DA-
15 interface. Similar, the PM103E is powered either via the ethernet interface or via the phoenix DMC
connector.
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 industrial
and scientific applications. The different electrical interfaces come with further functions ,
described in the following chapters.
4.2.1 PM103x Sensor Connector
All models of the PM103x have the same powermeter-sensor connector shown below. The Pin
assignment is engraved on the front of the PM103x.
