Chapter 3: System Setup
This chapter provides general information and procedures for setting up a PI-MAX4 system
for operation in both imaging and spectroscopic applications.
3.1 Dangers and Warnings
WARNING! RISK OF ELECTRIC SHOCK!
Voltages inside the PI-MAX4 may exceed 6,000 Volts. To
avoid possible hazard to personnel, use the instrument only
according to the directions in this manual and only for the
purposes for which it is designed. Never attempt to operate the
PI-MAX4 with its covers removed.
WARNING!
Image intensified cameras can be destroyed if exposed to excessive
light levels. Princeton Instruments cannot take responsibility for
PI-MAX4 camera damage due to misuse. Intensified cameras are
particularly susceptible to overload damage when operated in
conjunction with high-intensity light sources such as lasers. Spot
damage can occur without the overload condition being detected.
The PI-MAX4 is equipped with an audible alarm and shutdown circuit to bias the
photocathode OFF if excessive photocathode current is detected. The circuit automatically
resets and biases the photocathode back on after about 0.5 seconds. The short-term
protection provided will not prevent intensifier damage if excessive light is allowed to
continuously fall on the intensifier. It is also possible for excessively bright spots to damage
the intensifier tube without triggering the alarm.
3.2 Unpacking the System
During unpacking, check the system components for possible signs of shipping damage. If
there are any, notify Princeton Instruments and file a claim with the carrier. Be sure to save
the shipping carton for inspection by the carrier. If damage is not apparent but system
specifications cannot be achieved, internal damage may have occurred in shipment. Please
save the original packing materials so you can safely ship the camera system to another
location or return it to Princeton Instruments for repairs if necessary.
