Residual risks
Warning of electrical voltage
There is a risk of a short-circuit due to liquids
penetrating the housing!
Do not immerse the device and the accessories in
water. Make sure that no water or other liquids can
enter the housing.
Warning of electrical voltage
Work on the electrical components must only be
carried out by an authorised specialist company!
Warning of explosive substances
Do not expose the battery to temperatures above 60°C!
Do not let the battery come into contact with water or
fire! Avoid direct sunlight and moisture. There is a risk
of explosion!
Warning of laser radiation
Laser class3R, Pmax.: < 1.5–3mW, λ: 780nm,
EN60825-1:2014
Do not look directly into the laser beam or the opening
from which it emerges.
Never point the laser beam at people, animals or
reflective surfaces. Even brief eye contact can lead to
eye damage.
Examining the laser output aperture by use of optical
instruments (e.g. magnifying glass, magnifiers and the
like) entails the risk of eye damage.
When working with a laser of class2, observe the
national regulations on wearing eye protection.
Warning
Risk of suffocation!
Do not leave the packaging lying around. Children may
use it as a dangerous toy.
Warning
The device is not a toy and does not belong in the
hands of children.
Warning
Dangers can occur at the device when it is used by
untrained people in an unprofessional or improper way!
Observe the personnel qualifications!
Caution
Lithium-ion batteries might catch fire in case of
overheating or damage. Ensure a sufficient distance to
heat sources, do not subject lithium-ion batteries to
direct sunlight and make sure not to damage the
casing. Do not overcharge lithium-ion batteries. Only
use smart chargers that switch off automatically when
the battery is fully charged. Charge lithium-ion
batteries in due time before they are discharged
completely.
Caution
Keep a sufficient distance from heat sources.
Note
To prevent damages to the device, do not expose it to
extreme temperatures, extreme humidity or moisture.
Note
Do not use abrasive cleaners or solvents to clean the
device.

Information about the device
Device description
The particle counter is designed to measure the size and
number as well as the mass concentration of particles in the air.
The detected data can be used for analysing cleanrooms or
prove environmental burdens from particulates.
To detect the data, the particle counter sucks in air for a
selectable duration and determines the size and number or
mass concentration of particles contained in it.
Particles sized 2.5μm and 10.0μm are treated equally during
this process.
The detected values for all active particle sizes are
simultaneously displayed on a colour display. Additionally, the
air contamination is indicated on a colour scale. As soon as the
particle burden is no longer in the green area of this scale, a
beep is emitted (see table Alarm limit values for particle
concentration).
The device is equipped with an integrated measuring cell with
laser (class3R laser, 780nm, 1.5-3mW). Owing to the tamper-
proof enclosure it is classified as laser class1 (DINEN60825-1)
according to the Technical Regulations of the Occupational
Health and Safety Ordinance on Artificial Optical Radiation
(TROS) devised by the German Federal Institute for Occupational
Health and Safety. Maintenance and repair work may only be
carried out by trained expert staff observing the legal
regulations.
The device can be connected to another terminal device via
Bluetooth. In combination with the Trotec MultiMeasure Mobile
App, there are numerous possibilities for evaluating and
displaying the measured values.
The measurement results can be displayed and saved on the
terminal device either numerically or in form of a chart. Then,
the measurement data can be sent in PDF or Excelformat.
The app also includes a report generation function, an organiser
function, one for customer management and further analysis
options. Moreover, it is possible to share measurements and
project data with colleagues in another subsidiary. If
MultiMeasure Studio Professional is installed on a PC, you can
even use report templates and ready-made text blocks for
various fields of application to turn the data into professional
reports.

The current measured value and the corresponding unit are
displayed in the measured value field.
After several measurements have been carried out, the lowest
value, highest value, average value and current value are
displayed below the measured value field.
Depending on the setting of the measuring mode on the device,
the measured values are indicated on the display:
• particle concentration in Number per litre (n/l) or
• mass concentration(µg/m3)
You can change the indication by changing the measuring mode
on the device (see chapter Selecting the measuring mode).
After starting the measurement, a continuous measurement (X/T
measurement) is carried out according to the preset
measurement duration. The detected measured values are
indicated in the measurement value display.
The measured values can be displayed numerically or

Maintenance and repair
Charging the battery
The battery should be charged if the battery indicator(11) on
the device flashes or if the device can no longer be switched on
(see chapter Charging the battery).
Cleaning
Clean the device with a soft, damp and lint-free cloth. Make
sure that no moisture enters the housing. Do not use any
sprays, solvents, alcohol-based cleaning agents or abrasive
cleaners, but only clean water to moisten the cloth.
Repair
Do not modify the device or install any spare parts. For repairs
or device testing, contact the manufacturer.
Errors and faults
The device has been checked for proper functioning several
times during production. If malfunctions occur nonetheless,
check the device according to the following list.
Display segments are only faintly visible or flicker:
• The battery capacity is too low. Recharge the battery
without delay.
The device unexpectedly indicates an abnormally high or
inexplicable particle concentration at different locations in
the room:
• Check whether the device has been exposed to strong
sunlight or concentrated light from other (possibly artificial)
sources. This can affect the optical sensor and cause a
malfunction. For this reason, do not position the device in
exposed locations (e.g. on window sills).
• Switch the device off and restart it.
• If the device continues to indicate high values, use
another, comparable device (if possible) and check
whether it indicates a similar particle concentration.
– If the reference device, too, indicates abnormally high
values, it can be assumed that the particle
concentration is indeed significantly increased.
– If the reference device indicates a significantly lower or
negligible particle concentration while the affected
device continues to indicate excessive values after
another restart, the affected device must be repaired/
inspected.
Disposal
The icon with the crossed-out waste bin on waste
electrical or electronic equipment stipulates that this equipment
must not be disposed of with the household waste at the end of
its life. You will find collection points for free return of waste
electrical and electronic equipment in your vicinity. The
addresses can be obtained from your municipality or local
administration. You can also find out about other return options
that apply for many EU countries on the website
https://hub.trotec.com/?id=45090. Otherwise, please contact an
official recycling centre for electronic and electrical equipment
authorised for your country.
The separate collection of waste electrical and electronic
equipment aims to enable the re-use, recycling and other forms
of recovery of waste equipment as well as to prevent negative
effects for the environment and human health caused by the
disposal of hazardous substances potentially contained in the
equipment.
Li-Ion
In the European Union, batteries and accumulators must not be
treated as domestic waste, but must be disposed of
professionally in accordance with Directive 2006/66/EC of the
European Parliament and of the Council of 6September 2006
on batteries and accumulators. Please dispose of batteries and
accumulators according to the relevant legal requirements.
