Baseline Signal Suddenly Changes
A change in the baseline signal is normal if the temperature, gain, or speed setting has
been changed. If this occurs when none of these settings have been changed, there may
be excessive humidity in the camera vacuum enclosure. Turn off the camera and contact
Princeton Instruments Customer Support. See page 94 for contact information.

Camera1 (or similar name) in Camera Name field
When a PVCAM-based camera is detected/selected during the Camera Detection wizard
(formerly the Hardware Setup wizard), a default name such as Camera1 will be shown in
the Detected Hardware table and will be entered in the Camera Name field on the
Setup|Hardware|Controller/CCD tab page and in the Hardware Setup title bar.
Because this name is not particularly descriptive, you may want to change it. Such a
change is made by editing the PVCAM.INI file that is generated by Camera Detection
wizard (or by the RSConfig.exe if you have a software version 2.5.19.0 or earlier).
To change the default Camera Name:
1. Using Notepad or a similar text editor, open PVCAM.INI, which is located in
PhotonMAX System Manual
Turn off all AC power.
Verify that all cables are securely fastened.
Turn the system on.
If you hear 2 clicks separated by 1 second (shutter opening then closing), the
shutter is working. Call Princeton Instruments Customer Support for further
instructions.
