3.2.14 NTC Input
To monitor the temperature in a test environment, the PM103 has an NTC Input (DA-15 Pin 14)
which allows connection of an NTC thermistor. The measurement range is 0.1 100 kW. The
set range R0 and the bandwidth B for the NTC thermistor can be adjusted in the OPM software
or through SCPI commands. The default settings are 10 kW and 3988 K to directly access the
TSP-TH temperature probe. The measurement range with the PM103 is then -10 °C to 80 °
C with the TSP-TH.
Note
Connection of the NTC to the DE-9 Pin 7 of the Sensor Connector requires a resistance of 0.2
kW to 40 kW.
3.2.15 Power Supply
All PM103x models use the USB port for power supply. Please provide an appropriate connec-
tion to a PC or power bank.
Note
When operating the PM103 via the RS232 interface or completely autonomously via an analog
output, the unit can either be powered with 5 V via the USB connector or with any supply in the
range from +5 V to +36 V via the DA-15 connector (Pin 1 and Pin 9 (GND)). As an external
power supply, we recommend the DS5 5 VDC regulated power supply.
3.3 Software
The PM103x is operated remotely from a PC, laptop or tablet.
Thorlabs OPM Software
The Thorlabs Optical Power Monitor (OPM) software provides a Graphical User Interface to
view, log, and analyze measurement data. Download the OPM software package Version 2.3 or
higher from the Thorlabs website, via this link, through the software tab on the product website,
or through searching for the product name within the Thorlabs software website.
All information on software installation, device control and data management software can be
found in the software manual directly downloaded here.
Note
Do not connect the PM103x prior to software installation!
Attention
Exit all running applications on your PC as the installer may require a reboot of your PC during
installation!
Custom Made Software
The PM103x can also be run using custom made software. For this, please refer to the docu-
ment Write-Your-Own-Application (WYOA) for PM103x.
