THORLABS PM100D User Manual

4.2 Controlling the PM100D
measuring peak power levels the ‘HI’ setting is required so that the meter can follow
the signal.
4.2.4.1.2 Power Measurements with Photodiodes
Common photodiodes can be used for power measurements with the PM100D.
Therefore the PM100D needs to be set to the ‘Photodiode’ default setting in the
‘System Menu \ Measurement Settings’. A photodiode and an interlock must be
connected to the sensor input (see chapter 7.4 for the connector pin out); it is
important to attend to the right polarity (the cathode needs to be connected to
ground).
The operation is similar to photodiode power sensors with the exception that at the
soft button position of the wavelength menu a response value in A/W for one
wavelength can be set.
