3 Operation

3.1 Connecting a Power Sensor

The PM100A supports all Thorlabs 'C-Series' photodiode and thermal power
sensors. These can easily identified against older versions of Thorlabs power or
energy sensors by their red connector housing. The console will not recognize
sensors from the 'A' and 'B' series. Please contact Thorlabs for the upgrade of old
sensors with 'C-Series' connectors.
To plug or remove a sensor slightly press on the two bolts in the connector
housing, that fix it by resilience. Sensors can be 'hot-swapped' to the console, after
recognizing a new valid sensor the type and calibration data will be downloaded to
the console in approximately 2 seconds, and the unit is ready to operate with the
new sensor.
