3.1 How To
This chapter describes how to install the PM103x for standard measurements.
3.1.1 PM103x Setup
·
Download and install the Optical Power Monitor software on the device that will be used to
control the power meter interface (PC, laptop or tablet).
Note
Install the software prior to connecting the power meter interface to the PC (see Soft-
ware ).
· Connect the PM103x to a PC (Status LED turns yellow) or other power source (status
LED power supply turns green) via the USB port.
o
The PM103 accepts external power supplies with 5 V to 36 V via the DA-15 interface.
When connecting the USB port while using an external power supply via the DA-15
port, connecting the USB port will automatically switch to the 5 V power supply via
USB.
o
The status LED for the power supply is green when connected to an external power
supply via the DA-15 connector.
·
Connect the PM103x to a readout instrument (PC) using the USB cable or a matching
cable for the respective output port (SMA or DA-15). For PM103A and PM103, please
provide cables.
·
Connect a suitable sensor to the PM103x.
The sensor status LED indicates, when a sensor has been detected (green) or when no
sensor or no recognizable sensor is connected (red).
The Power Meter is now ready for operation and is recognized by the OPM software.
Note
For detailed instructions on controlling the PM103x through the OPM software, please down-
load the OPM
manual .
3.1.2 Connecting a Power Sensor
The PM103x supports all Thorlabs C-Series photodiode and pyroelectric sensors, that can be
identified by the red connector-housing of the DE-9 connector, compared to older versions of
Thorlabs power sensors. Sensor type and calibration data are saved in the non-volatile memory
of the DE-9 connector. Upon connection, this information is automatically sent to the PM103x
and to the controlling device (PC or else) and software. The software will automatically recog-
nize the sensor.
To plug-in or remove a sensor, slightly press on the two bolts in the connector housing, that fix
it by tension.
