This part of the instruction manual contains every specific information on the PM300E

optical power meter. A general description is followed by explanations of how to

operate the unit manually. You will also find information about a simple remote

control of the unit.

Attention

This manual contains ‘WARNINGS” and ‘ATTENTION” labels in this

form, to indicate danger for persons or possible damage to equip-

ment.

Please read these advises carefully!

NOTE

This manual also contains ‘NOTES” and ‘HINTS” written in this form.

1.1 Safety

1 General Information

The PM300E 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 Photodiode, Thermal,

Pyroelectric sensors and common Photodiode detectors, 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.

Before applying power to your PM300E system, make sure that the

protective conductor of the 3 conductor mains power cord is correctly

connected to the protective earth contact of the socket outlet!

Improper grounding can cause electric shock with damages 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

6.2) and the mains fuses (see section 6.3).

The power meter PM300E must not be operated in explosion endan-

gered environments!

Sensor, photodiode and control inputs and outputs must only be

connected with duly shielded connection cables.

Only with written consent from Thorlabs may changes to single compo-

nents be carried out or components not supplied by Thorlabs be used.

Do not obstruct the air ventilation slots in housing!

Do not remove covers!

Refer servicing to qualified personal!

This precision device is only dispatchable if duly packed into the

complete original packaging including the plastic form parts. If neces-

sary, ask for a replacement package.

1.1 Safety

Attention 

Mobile telephones, cellular phones or other radio transmitters are

not to be used within the range of three meters of this unit since the

electromagnetic field intensity may then exceed the maximum

allowed disturbance values according to IEC 61326-1.

This product has been tested and found to comply with the limits

according to IEC 61326-1 for using connection cables shorter than 3

meters (9.8 feet).

1.1 Safety

Attention 

The following statement applies to the products covered in this

manual, unless otherwise specified herein. The statement for other

products will appear in the accompanying documentation.

Note: This equipment has been tested and found to comply with the

limits for a Class B digital device, pursuant to Part 15 of the FCC

Rules and meets all requirements of the Canadian Interference-

Causing Equipment Standard ICES-003 for digital apparatus. These

limits are designed to provide reasonable protection against harmful

interference in a residential installation. This equipment generates,

uses, and can radiate radio frequency energy and, if not installed and

used in accordance with the instructions, may cause harmful inter-

ference to radio communications. However, there is no guarantee

that interference will not occur in a particular installation. If this

equipment does cause harmful interference to radio or television

reception, which can be determined by turning the equipment off and

on, the user is encouraged to try to correct the interference by one or

more of the following measures:

▪Reorient or relocate the receiving antenna.

▪Increase the separation between the equipment and receiver.

▪Connect the equipment into an outlet on a circuit different from

that to which the receiver is connected.

▪Consult the dealer or an experienced radio/T.V. technician for help.

Thorlabs GmbH is not responsible for any radio television interfer-

ence caused by modifications of this equipment or the substitution

or attachment of connecting cables and equipment other than those

specified by Thorlabs GmbH. The correction of interference caused

by such unauthorized modification, substitution or attachment will

be the responsibility of the user.

The use of shielded I/O cables is required when connecting this

equipment to any and all optional peripheral or host devices. Failure

to do so may violate FCC and ICES rules.
