1 Basic Safety Instructions

Intended Use

The PocketMonitor (PMT) is exclusively intended for measurements which are carried

out in or nearby the optical path of high power lasers. Other forms of usage are improper.

To ensure a safe operation, the device must only be operated according to the terms

stipulated by the manufacturer.

Using the device for unspecied use is prohibited strictly 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 on the device which causes scattered radiation (laser class 4).

That is why the applying safety regulations are to be observed and necessary protective

measures need to be taken.

Observing Applicable Safety Regulations

Personal protection is required when humans are present in a dangerous zone with

uncovered visible or invisible laser radiation or particularly uncovered laser beam

systems, beam guiding systems or process regions. This holds true for any application

of this equipment. During measurement procedures there is always an unavoidable risk

of laser radiation through direct or reected emissions. The applicable safety regulations

are 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 Protection” 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 systems

or laser processing areas, the following safety measures need to be taken:

• Please wear safety goggles adapted to the laser wave length and operating mode

of the laser beam source in use.

35,0(6

PocketMonitor PMT

Revision 01/2017 EN

• Depending on the laser source, it may be necessary to wear suitable protective

clothing or protective gloves.

• 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 suciently.

• 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 measuring device in order to prevent a

relative motion of the device to the beam axis. This reduces the risk of scattered

radiation and is also necessary to ensure an optimal performance for the

measurement.

Employing Qualied Personnel

All users of the PMT must have been introduced to the handling of the measuring device

and they need to have a basic knowledge about the work with high power lasers, beam

guidance systems as well as focussing units.

Modications

The PMT must not be modied, neither constructional nor safety-related, without our

explicit permission. Modications 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 nancial losses

due to a direct or indirect use of the measuring devices.

2 Symbol Explanation

The following symbols and signal words indicate possible residual risks:

DANGER

means that death or serious physical injuries will occur if necessary safety

precautions are not taken.

WARNING

means that death or serious physical injuries can occur if necessary safety

precautions are not taken.

CAUTION

means that a slight physical injury can occur if necessary safety precautions

are not taken.

NOTICE

means that property damages can occur if necessary safety precautions

are not taken.

The device itself or the packing bears the following symbols to indicate requirements

and possible dangers:

Read and observe the operating instructions and safety guidelines

before the start-up!

3 Conditions at the Installation Site

The measuring device must only be operated in a non condensing atmosphere.

4 System Description

The PocketMonitor consists of an absorber and a display as well as an operating unit.

Both components are connected via a swivel joint. In a folded state, the absorber protects

the display as well as the operating elements from damages of any kind.

For the measurement, the absorber is exposed to laser radiation. The microprocessor

based electronics measures the temperature rise of the absorber by means of which

the power of the laser beam is calculated.

The 4½ digit display either shows the measured laser power or the temperature of the

absorber.

A lithium cell supplies the PocketMonitor with current for approx. 10,000 measurements.

Depending on the dierent power ranges, six dierent absorber versions are available.

The special version has a separate absorber.

4.1 Measuring Principle

The laser power is measured according to the calorimetric principle. For the ballistic

measurement, the absorber is irradiated with the laser for a dened period of time. By

means of the known heat capacity, the measured temperature rise of the absorber and

the set irradiation time, the power can be measured.

5 Transportation

NOTICE

Danger of damage

Hard impacts and dropping the device can damage electronical com-

ponents.

Handle the measuring device with care both during transport and

assembly! If possible, please use the PRIMES transport box for the

transportation.
