3.2 Power Meter Interface Features

PM101x optical power meters offer full functionality to process signals from compatible photodi-

ode or thermal sensors to be displayed and analyzed on a connected PC.

PM101x general features

· All PM101x models have a non-volatile memory which prevents power meter settings from

being lost upon shutting down or rebooting.

· A fast readout rate of 1 kilo-sample per second permits online signal monitoring.

· Finely graduated thermal power ranges permit optimal resolution for thermal power measure-

ments.

· A Reset Button allows quick rebooting of the micro controller.

· The PM101x is powered either via the USB interface or via the DA-15 interface. A status LED

indicates appropriate connection to a power supply.

Beyond the above functions, the group of PM101x models offer individual electrical interfaces

for integration into different systems in industrial and scientific applications. The different elec-

trical interfaces come with further functions , described in the following chapters.
