1 General Information
The PM320E Benchtop Optical Power and Energy Meter is designed to measure the optical
power of laser light or other monochromatic or near monochromatic light sources and the
energy of pulsed light sources.
The dual channel design and compatibility to all Thorlabs “C-Series” Photodiode, Thermal,
Pyroelectric sensors as well as common Photodiode detectors, thermopiles and pyroelctric
elements, combined with a fast USB device interface open a wide range of applications in
Manufacturing, Quality Control, Quality Assurance, and R&D.
The provided software, including drivers and applications for LabVIEW and C makes it easy to
integrate the instrument in test and measurement systems.
1.1 Safety
Attention
All statements regarding safety of operation and technical data in this instruction manual
will only apply when the unit is operated correctly as it was designed for.
Prior to applying power to the PM320E, make sure that the protective conductor of the 3
conductor mains power cord is correctly connected to the protective earth ground
contact of the socket outlet! Improper grounding can cause electric shock resulting in
damage to your health or even death!
Also make sure that the line voltage setting of the fuse holder at the rear panel agrees
with your local supply and that the corresponding fuses are inserted. If not, please
change the line voltage setting (see section
) and the mains fuses
(see section
).
The PM320E must not be operated in explosion endangered environments!
Do not remove covers! Do not obstruct the air ventilation slots in the housing!
Do not open the cabinet, there are no parts serviceable by the operator inside!
Refer servicing to qualified personnel!
