for volatile organic compounds (VOCs) with a high stable hollow cathode lamp with Ceramic Discharge
Channel with an ionization potential < 10.6 eV. The use of new technologies for the excitation source
and the sensor allows a high stability of measurement and longer maintenance intervals. An integrated
active carbon filter and the circuit sampling an automatic purging and automatic calibration are
controlled.

2.4. Safety and Precautionary Measures to be adopted
WARNING
The following safety instructions must be observed implicitly. Only in this way can the
safety and health of the individual operators, and the correct functioning of the
instrument, be guaranteed.
•The device described in this manual must be installed, operated and maintained in strict
accordance with their labels, cautions, instructions, and within the limitations stated.
•The device is designed to detect volatile organic compounds or vapours in air.
•Do not mount the device in direct sunlight as this could cause overheating of the sensor.
•The device must be installed vertical with the filter port unit downward to avoid plugging of the gas
inlets by particles or liquids.
•The only absolute method to ensure proper overall operation of the device is to check it with a
known concentration of the gas for which it has been calibrated. Consequently, calibration checks
must be included as part of the routine inspection of the system.
•As with all devices of these types, high levels of, or long exposure to, certain compounds in the
tested atmosphere could contaminate the sensor. In atmospheres where the device may be
exposed to such materials, calibration must be performed frequently to ensure that the operation
is dependable and display indications are accurate.
•Use only genuine manufacturer replacement parts when performing any maintenance procedures
provided in this manual. Failure to do so may seriously impair instrument performance. Repair or
alteration of the device, beyond the scope of these maintenance instructions or by anyone other
than an authorised manufacturer service personnel, could cause the product to fail to perform as
designed.
•The device is designed for applications in hazardous areas under atmospheric conditions.
•Significant dust deposits on the gas inlets will increase the response time of the device. Checks for
dust deposits must be done at regular intervals.

4. Installation
The device should be installed where gas leaks are expected. The installation position depends on the
gas density, either in the upper area of the room under the ceiling for gases lighter than air or close to
the ground for gases heavier than air. Also, consider how air movement may affect the ability of the
device to detect gas. The display on the front of the instrument must always be clearly visible; the view
must not be obstructed.
Before beginning the installation, check that the delivered components are complete
and correct referring to the shipping documents and the sticker on the shipment carton.
When preparing the assembly, make sure that the mounting arrangement is correct for
the particular device.
4.1. Mechanical Installation
How To –Attaching to the Wall
1. Using the device fixing holes
(Ø 7 mm) as a template, mark the
holes for the two fixing screws.
2. Drill two holes of appropriate
diameter.
3. Attach the device to the wall,
vertical with the filter port unit
downward, using 6 mm diameter
screws with an appropriated
length, at the place of installation.
The device must be installed vertical with the filter port unit downward to avoid
plugging of the gas inlets by particles or liquids.
WARNING
The device contains high voltage parts inside. Disconnect the power supply before
maintenance and service.

6.1. Calibration
WARNING
Test gases used for calibration can be a health risk. Proper ventilation or extraction has
to be ensured.
General
The calibration must be done at regular intervals in accordance with applicable national and regional
regulations. The device calibration and the accuracy of the measuring can easily be checked at any time
by using the build-in Calibration Test function. The device must be calibrated after installation.
Connect power supply to the device at least one hour before attempting a calibration.
Preparations before Calibration / Calibration Test
To perform a calibration, you need a pressure cylinder of SPAN Gas and / or ZERO Gas, a flow reducer,
a tube and a T-piece. The flow reducer should provide a flow of at least 500 ml/min. The T-piece should
be installed between flow reducer and sample port –dust filter. The open tube length on T-piece
junction should be 300 –500 mm. (see following connection scheme)
For calibration, it is recommended to use the Calibration Kit from accessories. (see
chapter 14 Accessories)

6.1.1. Calibration Procedure
Calibration Methods
The device supports two different methods for calibration. (Standard Calibration with SPAN Gas
[Isobutene in air] and Extended Calibration with SPAN Gas [User gas in air] with known concentration)
Which calibration method is carried out, depends on the measurement task, e.g. overview
measurements, workplace monitoring, control measurements, worst-case measurements,
environmental measurements and emission measurements.
Both calibration data for Extended Calibration and Standard Calibration are stored
independently of one another. Via the Instrument Menu >> MEAS CONFIG, the user can
choose most appropriate calibration data setting for his measurement application.
Both calibration methods using a two-point-calibration, which can be performed as a manual or an
automatic calibration.
Manual Calibration Mode
•Both, fresh air (ZERO Gas) and calibration gas (SPAN Gas) must be applied successively to the
Sample Port –Gas Input.
•The user will be asked for applying the right gas during the calibration sequence.
Automatic Calibration Mode
•Only, calibration gas (SPAN Gas) must be applied to the Sample Port –Gas Input.
•Fresh air (ZERO Gas) will taken automatically from the Filter Port –Cartridge.
•The device selects the gas input automatically during the calibration sequence.
After starting any calibration, calibration gas [ZERO or SPAN Gas] must be applied until
calibration step is finished. The calibration procedure can be cancelled at any time by
pressing “abort”. The previous device calibration will be used.
How To –Start Calibration
1. Go to the Instrument Menu and select CALIBRATION
2. Select “run” to go to calibration screen and select START (Start new calibration)
3. Press “accept” to start new calibration and follow the instructions on the screen
