4.3. Setting up PMTSS Series
WARNING
DO NOT switch on the light source until the setup is complete. Use proper eye and skin
protection for the corresponding wavelength in use while setting up the photomultiplier tube to
detect hazardous wavelengths, such as UV, blue lights, and other high intensity radiations.
WARNING
Use proper eye and skin protection for the corresponding wavelength in use while operating
the photomultiplier tube with hazardous wavelengths, such as UV, blue lights, and other high
intensity radiations.
CAUTION
DO NOT expose the photomultiplier tube to strong light sources (especially UV). They can
temporarily increase the noise in the signal.
4.3.1. Preparation
1. Mount the PMT on your optical table or application.
2. Connect the PMT Pre-Amp Bulkhead Internal Power cable Pin 1 to a standard power supply and Pin 2
(0.25
– 1.2 V) to a voltage control unit.
3. Connect the output signal to a data acquisition system.
4. Align the light source to the PMT input, and switch on the light source.
5. Remove the C-Mount cap (PMTSS module).
6. Vary the voltage in the voltage control unit to control the PMT gain.
4.3.2. Expanding the Detection Channels (PMTSS2)
Add the PMTSS2-SCM module to the PMTSS2 module to increase the number of detection channels. The PMTSS2
module is expandable to up to eight detection channels.
CAUTION
DO NOT switch on the photomultiplier tube module while installing additional detection channels.
Stray lights may temporarily increase the noise in the signal and may damage the detector element.
