1 Basic safety instructions
Intended use
The PowerMeasuringCassette-Compact PMC-C is used to measure the power of lasers
directly in the BEO laser processing head. Please observe and adhere to the specifica-
tions and limit values given in chapter17, „Technical data“, on page45. Other forms
of usage are improper. The information contained in this operating manual must be
strictly observed to ensure proper use of the device.
Using the device for unspecified use is strictly prohibited by the manufacturer. By usage
other than intended the device can be damaged or destroyed. This poses an increased
health hazard up to fatal injuries. When operating the device, it must be ensured that
there are no potential hazards to human health.
The device itself does not emit any laser radiation. During the measurement, however,
the laser beam is guided onto the device which causes reflected radiation (laser class
4). That is why the applying safety regulations are to be observed and necessary pro-
tective measures need to be taken.
Observing applicable safety regulations
Please observe valid national and international safety regulations as stipulated in ISO/
CEN/TR standards as well as in the IEC-60825-1 regulation, in ANSIZ136 “Laser
Safety Standards” and ANSI Z 136.1 “Safe Use of Lasers”, published by the American
National Standards Institute, and additional publications, such as the “Laser Safety
Basics”, the “LIA Laser Safety Guide”, the “Guide for the Selection of Laser Eye Protec-
tion” and the “Laser Safety Bulletin”, published by the Laser Institute of America, as well
as the “Guide of Control of Laser Hazards” by ACGIH.
Taking necessary safety measures
If there are people present within the danger zone of visible or invisible laser radiation,
for example near laser systems that are only partly covered, open beam guidance sys-
tems or laser processing areas, the following safety measures need to be taken:
• Please wear safety goggles adapted to the power, power density, laser wave
length and operating mode of the laser beam source in use.
• Depending on the laser source, it may be necessary to wear suitable protective
clothing or protective gloves.

Revision 01/2018 EN
• Please protect yourself from direct laser radiation, scattered radiation as well as
from beams generated from laser radiation (e.g. by using appropriate shielding
walls or by weakening the radiation to a harmless level).
• Please use beam guidance- or beam absorber elements which do not emit any
hazardous particles as soon as they get in contact with laser radiation and which
resist the beam sufficiently.
• Please install safety switches and/or emergency safety mechanisms which enable
an immediate closure of the laser shutter.
• Please ensure a stable mounting of the device in order to prevent a relative motion
of the device to the beam axis of the laser and thus to reduce the risk of stray
radiation.
Employing qualified personnel
The device may only be operated by qualified personnel. The qualified personnel must
have been instructed in the installation and operation of the device and must have a
basic understanding of working with high-power lasers, beam guiding systems and
focusing units.
Conversions, modifications and repairs
The device must not be modified, neither constructionally nor safety-related, without
our explicit permission. The device must not be opened e.g. to carry out unauthorized
repairs. Modifications of any kind will result in the exclusion of our liability for resulting
damages.
Liability disclaimer
The manufacturer and the distributor of the measuring devices do not claim liability
for damages or injuries of any kind resulting from an improper use or handling of the
devices or the associated software. Neither the manufacturer nor the distributor can be
held liable by the buyer or the user for damages to people, material or financial losses
due to a direct or indirect use of the measuring devices.

3 Conditions at the installation site
The device must only be operated in a dry and dust free atmosphere. High levels of
humidity can lead to condensation, which can affect the operation of the device. This
also applies to high environmental dust exposure.
In industrial environments erroneous measurements may be triggered by strong elec-
tromagnetic fields. In this case we recommend EMC compliant shielding of the interlock
cable.
4 Special Instructions for measuring devices with
rechargeable lithium ion batteries
The device is equipped with a lithium-ion battery. Note that this battery may ignite or
explode at high temperatures.
To operate the device, the ambient conditions must therefore be observed and adhered
to in accordance with the specifications in chapter17, „Technical data“, on page45.
The lithium-ion battery is permanently installed in the device. Do not open the device
to replace the lithium-ion battery, as damage to the battery may result in the escape of
harmful substances.

5.1 Measuring principles
The absorber of the calorimetric measurement system is irradiated by a laser for a short
period of time. The temperature difference of the absorber between start and finish
of the laser pulse is measured. From the increase in temperature, the microprocessor
based electronics is able to calculate laser power to a high degree of accuracy.

12 Description of the PRIMES Cube App
12.1 Application
The PRIMES Cube App is an application for smartphones/tablets with Android™ used
for mobile measurement of laser power.
A bluetooth connection with the PRIMES measuring device makes it possible to read
out and graphically display the measured values (laser power, pulse length, and energy
per pulse) with the mobile end device. The app also shows an overview of the device
status (temperature, capacity, status notifications).
Other functions: Setpoint values can be entered by the user and stored in a table as
default settings. When a measurement is performed, the actual measured values of the
PRIMES measuring device are added to the table, thus enabling a tabular and graphic
comparison of the target and measured values as well as a graphic illustration of the
percentage of deviation of the measured value from the setpoint value.
12.2 System requirements
The PRIMES Cube App can be used on a smartphone/tablet with an Android 4.1 oper-
ating system or higher and a display resolution of HVGA 320x480 or higher.
12.3 Download
The PRIMES Cube App can be downloaded from the Google Play Store/Apps for free.
You will need a Google account for this. Enter the search term “Primes Cube App” in
