The monitor has several essential operational features, which enable
you to operate it without undue reference to this Instruction Manual.
The main features of the monitor which ensure its simple and easy
operation, are listed below:
• The fully, comprehensive Software’s BZ7002 and BZ7003.
• The LumaSoft Gas Single Point 7810 application software.
• The short, self-explanatory texts, which appear in the monitor
display when the monitor is being used, give operational guidance
to the user.
• The small light-emitting diodes at some of the push-buttons allow
the user to identify how the monitor is operating at any particular
time.
• Audible warning “beep” if any push-buttons are used in the wrong
way.
3.1 PC Use – Online
A monitoring system, where you use the PC environment to set-up
the monitor prior to measuring, display measurement data on the PC
screen while monitoring and store the measurement results directly
on the PC’s hard disc. The LumaSoft Gas Single Point 7810
application software is used for making online measurements. The
measurement results can be used by other programs that fetch data
from the SQL Server Express database server featured by the 7810
application. A manual BE6027 for the 7810 application is available
for reference.
Using the online mode (7810 Application Software) provides you with
a variety of Software Alarm options. Not only are the alarm trigger
levels definable, but the action resulting from an alarm being
triggered can also be defined here. This enables you to connect
external warning systems to the monitoring system.
The philosophy behind the 7810 Application Software is common to
almost all Windows programs. Access to the various levels of the
program is gained by use of the MENU BAR, PULL-DOWN MENUS,
NEW WINDOW options and INDEX-CARD separators. These familiar
procedures, together with the simple software structure, make the
instructions in the On-line sections of this manual understandable
and easy to implement.
3.2 Stand-alone Use
This method of operation is available to those of you who wish to use
the monitor without connection it to a PC. The monitor is set-up and
the results are displayed via the monitor’s front panel.

______________________________________________________________________
The Monitor is an extremely versatile measuring instrument, which
can be used to perform almost any kind of monitoring task. Its
versatility may appear overwhelming at first, but to avoid such a
reaction, we suggest that you read this chapter thoroughly, and
follow the practical exercises, which are included. These exercises
give you a “guided tour” through a number of different practical
procedures – monitoring task; performance of a monitoring task;
scrolling through data after completion of a monitoring task. By
following these different procedures the Monitor operating philosophy
will become apparent and you will be able to quickly familiarise
yourself with its operation and control.
4.1 Special Terminology
Certain terms are used to describe the operation of the Monitor and
it is necessary to fully understand what these terms mean before you
start any practical exercise with the Monitor.
4.1.1 Measurement Cycle
A description of a measurement cycle is given on page 2 of the
Product Data Sheet (see boxed-in text and schematic diagram of the
measurement system of the Monitor). “Measurement Cycle” is the
term used to describe everything that takes place in the Monitor from
the time the pump starts to flush out the “old” gas sample in its
analysis cell, until the signal in the measurement chamber has been
measured using the last relevant optical filter.
The time taken to complete a measurement cycle is dependent upon
the following factors:
How many gases/vapours are being measured – this affects the
number of optical filters which need to be used.
The sample integration time selected – longer measurement times
provide greater accuracy.
The flushing times selected for the measurement chamber and the
tube as well as the length of the sampling tube attached to the
Monitor’s air-inlet – the longer the tube, the more time is needed to
flush it out between measurement cycles.
The cleanliness of air-filters which filter the air drawn into the cell
(this affects the pumping time required to draw a fresh air sample
into the analysis cell).
The degree of fluctuation in the concentration of the various gases
measured in consecutive measurement cycles (this affects the time
required to adjust the gain of the amplifier attached to the
microphones).

______________________________________________________________________
Table 4.1 gives some indication to the measurement times depending
on the number of gases measured and the measurement times
selected. However, these times may vary from one measurement
cycle to another due to the cleanliness of the filters and the degree
of fluctuation in the concentration of the various gases.

4.1.2 Monitoring Task
A monitoring task consists of a series of similar measurement cycles.
These cycles can either be repeated at regular intervals or be
continuous:
4.1.3 Sampling Interval
The sampling interval is a measure of the time between the start of
one measurement cycle and the start of the following measurement
cycle.
When the Monitor is not sampling continuously the sampling interval
has to be defined by the user and is a fixed period of time (see
Fig.4.1).

when it is not sampling continuously.
4.1.4 Continuous Sampling
The Monitor is said to be sampling continuously when each
measurement cycle is followed immediately by another similar
measurement cycle (see Fig.4.2).
Fig.4.2 An illustration of continuous sampling
4.1.5 Monitoring Period
The monitoring period is the time between the start of the first
measurement cycle in a monitoring task and the finish of the final
measurement cycle in a monitoring task.
The monitoring period can either be pre-set by the user – in which
case the Monitor automatically stops monitoring after the monitoring
period is over – or, not pre-set – in which case the Monitor will
continue to monitor until the user stops the monitoring task manually
(see section 4.3.8).The maximum time you can set a pre-set
monitoring period to be is 7 days. If You try to enter a greater
number of days, the Monitor will automatically change the period to
7 days. However, if you do not set a predefined monitoring period,
_____________________________________________________________________________

Page 33 of 199
Chapter 4
______________________________________________________________________
the Monitor will just store as much data as possible before starting to
overwrite the oldest stored measurement results.
4.2 Attaching the Sampling Tube and External Filter
1 Cut a short section of sampling tube of Poly-Tetra-Fluoro-
Ethylene (Teflon) tubing, (optional accessory).
2 Using Fig.4.3 and the instructions below, attach one end of this
tube to the air-inlet stub on the back-panel of the Monitor.
Push one end of the Teflon tubing through the non-threaded end
of the nut.
Hold the end of the tubing between the fingers and gently push
the tubing over the end of the Monitor’s air-inlet stub as far as it
will go.
Note: if the tubing is bent/broken during this procedure, remove
the tubing from the stub and repeat this step using an
undamaged length of tubing.
Screw the threaded-nut firmly onto the end of the air-inlet stub.

4.3.2 Setting Units
All data in the Monitor is stored as raw data. The different units,
which you can select here, enable you to enter gas concentrations
and to display temperatures, lengths and pressures in units, which
you are comfortable with. These units are also used to present
measurement data in a form that is most convenient for you.
The Monitor can display gas concentrations either in absolute units of
mg/m3 unit that is dependent on a particular temperature, termed
the normalization temperature, or in units of parts per million (by
volume) – which is independent of the temperature of the gas. You
can inform the monitor about the units you intend to use – for
example: the length of the sampling tube attached to the Monitor’s
inlet (in meters or feet) atmospheric pressure (kPa or mBar or
mmHg) and unit for humidity (ppm or Tdew or kPa or mg/m3).
The measurement units can be changed using the push-buttons on

The Monitor measures gas concentrations in the absolute unit of
mg/m3 – a unit which is dependent on temperature. Alternatively,
the Monitor can calculate gas concentrations in parts per million
(ppm) by volume – this unit is independent of the temperature of
the gas. If mg/m3 is chosen as the gas concentration unit it is
therefore necessary to define the temperature at which you wish the
Monitor to calculate gas concentrations. This pre-defined
temperature is termed the NORMALIZATION TEMPERATURE.

4.3.4 Setting up a Monitoring Task
The optical filters in the monitor have to be calibrated before they
can be used to measure gas concentrations. The user can only set-up
a monitoring task using those optical filters which have been
installed. In this example we have chosen to measure gas A (that is,
to measure gas A’s concentration using the optical filter installed in
position “A” of the filter carousel) and water vapour.
If your Monitor has only been calibrated to measure with another
filter (for example, the filter in position “B”) then choose gas B to
replace gas A in the following instructions. The parameters which
describe the monitoring task we shall set-up, are listed below:

While a monitoring task is being performed a running statistical
analysis of the monitored gases/vapours is made and the results are
displayed as shown above, where:
MAX = maximum concentration of gas A measured during the
period of time the monitoring task has been performed.
MIN = minimum concentration of gas A measured during the
period of time the monitoring task has been performed.
ALARM 1= the user-defined concentration of gas A which, if
measured by the Monitor, will trigger a switch in the
Monitor and activate an external alarm relay connected to
it.
= linear average, or mean value, of all the gas A
concentrations measured during the period of time the
monitoring task has been performed
= standard deviation of gas A’s concentrations from the
mean value (m) described above (see section 8.1 for
further details).
All numbers are written in the exponential form, for example:
84.5E+00 = 84.5 x 10+0 = 84.5
The concentration unit in this case is mg/m3 as this was chosen in
the active set-up (see section 4.3.2).

As you can see, the display provides the date and time at which the
measurement was made, and the concentration of gas A is given in
the units mg/m3 because this was the unit chosen for gas
concentration in the active set-up. The dashed lines, which appear
after the time will be replaced by a number as soon as the
monitoring task has been stopped (see section 4.3.8).

The humidity unit in this case is Tdew because this is the unit chosen
in the active set-up (see section 4.3.2).
As you can see the measurement cycles are numbered sequentially
as soon as the monitoring task has been stopped for example, the
above measurement was made at 09:51:33 on the 16th of January
and it was the second measurement cycle of the monitoring task.
The concentration of water vapour is given in the units of Tdew
because this was the unit chosen for humidity in the active set-up.

4.3.10 Changing Gas-concentration Units after a Monitoring Task
The unit mg/m3 was chosen for gas concentrations in the monitoring
task, which was set up in section 4.3.4. As long as mg/m3 is the
active concentration unit (that is, the unit selected while operating
in Set-Up mode), this is the unit which will be used to express gas
concentrations on the display screens of the PC and the Monitor. It is
also the unit when print-outs of monitoring task data are made from
the Monitor. However, the user can express the measured gas
concentrations in ppm:
1. Press SET-UP S3 S2 S3 and then SET-UP.
2. Use q to scroll through the results of the monitoring task no. 1
displayed on the screen. Notice that the gas concentration units

5.1 Introduction
This chapter is primarily for those users who want to use the monitor
as a stand-alone instrument. But the start-up and alarm relay
sections are also of interest for the PC user.
5.2 Front Panel
The front panel of the monitor is dominated by a 2 x 40 character
fluorescent display screen, 3 Select push-buttons located beneath it
and 5 direction push-buttons (see Fig. 5.1). The rest of the pushbuttons, situated in a line along the bottom, are function pushbuttons.
Fig.5.1 The front panel of the 1314i
Small light-emitting diodes (LEDs) are mounted above some of the
front-panel push-buttons. Their function is to inform you of the
operating state of the monitor. For example, if the LED above the
MEASURE push-button is lit, it indicates that the Monitor is either
busy performing measurements or has been set-up to start
measurements at a pre-defined time.
5.2.1 Direction Push-buttons
This group of 5 push-buttons is referred to in this manual as the
direction push-buttons.
▲ & ▼ have two uses: to increase & decrease numbers, respectively,
or to go to the Previous & Next Displays, respectively.

______________________________________________________________________
The number increase and decrease functions are used whenever
values, which can be changed manually, are displayed on screen,
for example, changing a parameter such as the length of sampling
tube.
The “Previous Display” and “Next Display” functions are used when
you want to view the previous or next screen texts. This can be
useful when setting up the monitor. By using these push-buttons,
you can scroll quickly through a branch of the Set-Up Tree. These
push-buttons can also be useful when viewing measurement data,
for example, if you are looking at gas A’s measurement result no.3
– by pressing ▲, gas A’s measurement result no.2 will be shown
on the screen. By pressing ▼, gas A’s measurement result no.4
will appear on the display screen.
◄ & ► enable you to move across number fields or go to the
Previous & Next gases, respectively.
When you are entering values or names in the monitor, for
example when setting up the monitor, you can use these pushbuttons to move the cursor across the entry fields.
“Previous Gas” & “Next Gas” functions, are used primarily when
viewing measurement data. The display screen only displays the
measurement data for one gas at a time (out of 5 gases and water
vapour). These push-buttons allow you to look at the
measurement data for any one of the 4 other gases and water
vapour (see Fig.4.4 and section 4.3.9).
Depending on the situation, this push-button acts as either an
“Enter” or “Go To Top of Measurements” function.
The “Enter” function is used whenever measurement units are
selected or any text, for example filter names or gas names, are
being entered. The Monitor display will typically display a text
similar to PRESS ENTER TO CHANGE VALUE.
The “Go To Top of Measurements” function is used in the following
situations:
• If you are viewing measurement data, when
is pressed, the
display will move to the screen showing the text DATA IN
DISPLAY MEMORY RECORDED FROM… which gives the period
of time data was recorded – see Fig.4.4 for details.
• If the Monitor is performing measurements when
is pressed,
the Monitor will display the last measured concentrations of all
the gases.

• Acknowledge any message, which may appear on the
display screen during operation of the Monitor.
• Obtain more detailed information about the condition
of the Monitor at any particular moment of time, if
such information exists.
PRINT By pressing this push-button, measurement results in the
Display memory of the Monitor can be printed out. The
lamp above this push-button is lit, while measurements
are being printed and the display will show PRINTING
MEASUREMENT DATA until all data has been printed out.
SET-UP In this mode you are able to enter the Set-Up Tree of the
Monitor. In set-up mode, the user is able to program the
Monitor to perform almost any kind of measurement, and
amongst other things; enter data about the optical
filter(s) which are installed in the Monitor; select different
measurement parameters; choose how measurement results should be formatted in print-outs; choose the
interface and communication codes which are necessary
to print data; set the internal clock of the Monitor and
choose the self-tests the Monitor should perform.
When the Talk/Listen LED is lit, this means that there is activity on
one of the interfaces.
5.3 Starting-up or Restarting the Monitor
5.3.1 Introduction
When the monitor is started up in the normal way, that is, by
switching on the AC Mains power-switch on the back panel, the
monitor responds by performing a partial reset. A partial reset is
also performed if during operation the monitor is switched off and is
re-started in any of the following ways:
• If the Monitor stops operating due to an AC mains power failure
and then re-starts itself (automatically) when power is restored to
it;
• If the user stops operating the Monitor by switching it off using
the AC mains power switch on the back panel, and then re-starts
it by using the same switch:
Users can also “partially reset” the Monitor by using the RESET
push-button on the front panel (see section 5.2.3).

Chapter 5
______________________________________________________________________
5.3.2 A Partial Reset of the Monitor
When the Monitor performs a partial reset a number of self-tests
are automatically performed. The types of tests performed depend
only upon the time, which has elapsed since the Monitor was last
switched on.
• If more than 10 min. have elapsed since the Monitor was
switched on it will perform the software, data-integrity, and
hardware tests when switched on again.
• If less than 10 min. have elapsed since the Monitor was switched
on it will perform only the data-integrity tests when switched on
again.
There are essentially 3 types of self-tests which can be performed
during a “partial reset” – a software test, a data-integrity test and
a hardware test.
It takes the Monitor only a few seconds to perform the data-
integrity tests; and about 3 minutes to perform both the software
and hardware test. The different tests are explained below.
Software test
This test checks the information in the Monitor’s software (ROM –
Read Only Memory.)
Data-integrity test
This test checks the integrity of the data stored in the Monitor’s
Source Memory (i.e. its EEPROM – Electrically Erasable
Programmable Read Only Memory) and the integrity of the data
stored in the Monitor’s Working Memory (RAM).
Hardware test
This test checks that the electrical, mechanical and electronic
parts of the Monitor are functioning properly.
The following parts of the Monitor are checked: the pump; the
valves in the pneumatic system; the infra-red light source; the
power supply; the filter carousel; the motor which drives the
chopper wheel; the external vibration level (to make sure that it
does not contribute to the signal measured in the analysis cell);
the analogue circuitry and the microphones (to check that they
are functioning properly).
If you do not wish the Monitor to perform the hardware test
during a partial reset, you can disable it (see section 5.4.3). This
also disables the regular self-tests.
If any part of the Monitor is found to be functioning incorrectly a
message will appear in the display to inform the user of the problem.
For example:
_____________________________________________________________________________
BE6030-13 1314i Photoacoustic Gas Monitor LumaSense Technologies A/S
Page 61 of 199
Chapter 5
OPERATING ERROR:
______________________________________________________________________
PUMP TEST FAILED
The user must acknowledge receipt of such a message by pressing
INFO. Operating errors and warning messages are listed in tableform in Chapter 15 at the end of this manual.
If a fault is found in any of the blocks of data stored in the Working
Memory, the Monitor will automatically set the parameters in the
relevant compartment(s) to their default values, and the Monitor will
send the following message on its display screen:
WARNING: MEMORY SET TO DEFAULT
ERROR DETECTED IN XXXXX MEMORY
Where XXXXX denotes the part of the memory that has been
affected. When such a message is received users must check the
contents of the relevant memory to find out which data has been
affected before continuing to operate the Monitor.
5.3.3 Response of the Monitor after a Partial Reset
The way in which the Monitor responds after a partial reset is
dependent upon the way it was being operated at the time of the
partial reset (see Table 5.1). For example, if the Monitor was busy
taking a measurement when it was “partially reset” it will complete
the interrupted measurement after the partial reset, continue its
monitoring task and make a special “mark” alongside the first
complete measurement cycle it performs after the reset. These
“marks” are described in section 8.2.2 and section 8.2.3.

There are two well-defined levels of reset. By pressing RESET the
following text appears on the display screen:
PARTIEL FULL NONE
If S3 is pressed, you can come out of reset mode without performing
any kind of reset. The Monitor just goes back to operating the same
way it was operating before the RESET push-button was pressed.
S1 PARTIAL Reset: If this level of reset is chosen the Monitor
stops operating, performs a partial reset as described in the
previous section (section 5.3.2) and then resumes operating in
the fashion described in Table 5.1.
S2 FULL Reset: If this level of reset is chosen the Monitor responds
by changing the text on the display so that you have a chance to
confirm that you wish the Monitor to perform a FULL reset:

______________________________________________________________________
NO YES
S1 By pressing this push-button the user can come out of reset
mode without performing any kind of reset. The Monitor just
goes back to operating the same way it was operating before
RESET was pressed.
S3 By pressing this push-button the user confirms that a FULL
reset is required. During a FULL reset the Monitor performs the
following two tasks:
• “Clearing” (emptying) all data from its Working Memory.
This means all data in Display Memory and Background
Memory will be lost.
• Copying data from its Source Memory into its Working
Memory. This means that set-up parameters in block 3 of
Working Memory “Other Set-up Parameters” will be given
their default values, and the values of the optical filter set-
up parameters in Working Memory will be the same as
those found in Source Memory.
5.4 Configuring the Monitor
5.4.1 Setting the Clock
Before dispatch from the factory, the internal clock of the Monitor is
set to the correct local (Danish) time.
The current date is entered as Year-Month-Day for example the
24th of July 2014 is entered as 2014-07-24.
The current time is entered as the time on the 24-hour clock for
example 14:05 is five minutes after two in the afternoon. Table
5.2 details the range of acceptable values and the default value of
the date and time.

5.5 Alarm Relay
Two alarm relays are built into the alarm relay socket on the
back panel of the Monitor. The function of the pins in this female
connector are shown in Fig.5.2. The two alarm relays can be
connected to a variety of either audio (for example, a siren)
and/or visual (for example a flashing light) alarm systems and
they are activated whenever a pre-defined concentration (alarm
level) of one (or more) of the gases being measured is exceeded.
Alarm signals are given by opening and closing the relay contacts.
Both relays are closed when the Monitor is switched off and when
the Monitor is switched on. This means that there is a direct
electrical connection between pins 1 & 2 and pins 4 & 5 at all
times except when the Monitor measures a gas concentration
which is greater than the corresponding alarm limit for the gas.
When this concentration is measured, the Monitor breaks the
connection between pins 1 & 2 or 4 & 5. The monitor will
furthermore activate the internal beeper and write the following
message on the display:
_____________________________________________________________________________
BE6030-13 1314i Photoacoustic Gas Monitor LumaSense Technologies A/S
Page 67 of 199
Chapter 5
WARNING:
Alarm relay 1
Alarm Relay 2
______________________________________________________________________
ALARM LIMIT EXCEEDED
The user can switch off the beeper and the message by pressing
INFO or RESET push-button on the front-panel of the Monitor.
The alarm relays will continue being activated until either (1) all
measured gas concentrations fall below their user-defined alarm
level(s); or (2) the monitoring task is stopped – this automatically
closes the alarm relays.
Alarm Relay 1:
Alarm Relay 1: correspond to High Alarm Limit 1.
Whenever one or more gases exceed their alarm level(s) for high
alarm limit 1, the Monitor breaks the electrical connection
between pins 1 & 2 and this activates the attached alarm system.
Alarm Relay 2:
Alarm Relay 2: correspond to High Alarm Limit 2.
Whenever one or more gases exceed their alarm level(s) for high
alarm limit 2, the Monitor breaks the electrical connection between
pins 4 & 5 and this activates the attached alarm system.
LumaSense supplies a 6-pin DIN plug (male) with a locking collar
JP0600 for connecting external alarm devices to the alarm relay.
Caution:
The DC voltage across the relay contacts must not exceed 25V. The
potential on the relay contacts must not be more than 25VDC above
chassis potential, as this will cause an excessive leakage current. The
current through the contacts must not exceed 100mA. AC voltages
must not be connected to the Alarm Relay socket.

6.1 Types of Parameters
There are four types of parameters:
Numerical: you are free to enter the desired values. However, there
may in many instances be a range in which your values must lie.
These ranges can be found in the relevant sections of this manual.
Text: you are able to type user-defined text, for example, the names
of the gases you are measuring and when using the PC the names of
your databases.
The characters available to you when using the monitor on its own
are shown in the table below:

Pre-defined: you are able to select a parameter using the “select”
push-buttons when there are three or less options, or by scrolling
through a pre-defined list using the direction push-keys. The
parameters in the lists are given in more detail in the relevant sections of this manual.
Current Time: in the monitor is synchronized to match the time and
date of the internal clock in the PC when the two are connected
together. However, it is possible to adjust the monitors date and
time using the front panel push-buttons. This is described in full in
section 5.4.1.
Stand-alone Use
Whenever you are choosing parameters and/or “entering” parameter
values via the front-panel push-keys, two options are available:

CANCEL This option appears over the S1 select push-button. If
you change the value of a parameter on the display
screen and then decide that the new value is not correct,
the original parameter can be brought back to the screen
by pressing S1.
Default This option appears over the S3 select push-button. If
you wish the parameter appearing on the display screen
to be the same as the factory-defined value you can
press S3.
Some parameters do not have pre-defined default values, so that
when Default is used a blank line will appear instead of a number.
The default value of such a parameter is said to be “blank”. For
example:
If the value of a chosen parameter lies outside the pre-defined
minimum and maximum values the value will be corrected and, at
the same time, a “beep” will sound. You will then have to “enter” the
correct value by pressing ↵ and repeating the process.
When you have to choose or change a parameter, and the text
PRESS ENTER TO CHANGE VALUE is displayed, use the direction
push-buttons and follow the procedure below. Details about the
direction keys are provided in section 5.2.
1. Press
. A cursor will blink under one of the parameter’s numbers
or letters and the bottom line will display the soft-keys Cancel

Before a measurement task can commence, there are a variety of
parameters that must be defined first. This is called “Setting up the
Monitor”.
This chapter instructs you on how to set up the monitoring system
before starting to measure. As mentioned previously in this manual,
the parameters can be defined using the PC Use instructions, i.e.
when using a PC, or the stand-alone Use instructions, i.e. when using
the front panel push-keys on the monitor.
Before leaving the factory, each of the parameters found in the setup “tree” (see the Quick Set-up Guide) are given factory values
(default values).
When setting-up the Monitor as a stand-alone instrument, those
values with a cursor underneath them are the active values. It is
the active values, which determine how the Monitor will operate.
Warning! Failure to define any parameter may result in the default
parameters being used. This can result in the monitor measuring
incorrectly or being unable to start the measurement task.
7.1 The Parameters’ Units
The Monitor works internally with measurement parameters in SI
units. These units can be converted and displayed as a variety of
other measurement units. Defining the units here has two uses. It
enables you to set-up the measurement parameters using familiar
units and displays the measurement results with the desired
concentration units.
These parameters are listed below.
Table 7.1 The possible parameter units and the default settings
The units for existing measurement results can also be changed
using these instructions.

7.1.1 Normalization Temperature
If you have chosen to measure gas concentrations in the unit
mg/m3, you must “enter” the temperature at which the Monitor
should calculate gas concentrations. If, for example, you “enter” a
normalization temperature of 25°C, the measured gas
concentrations, which appear on the display during a monitoring task
will be calculated in mg/m3 units at 25°C. The acceptable values and
the default values of the normalization temperature are given in
Table 7.2 in the different temperature units.
Table 7.2 The acceptable values and the default values of the
normalization temperature
If you set up the monitor using the front panel push-buttons, the
instructions to set the normalization temperature are included in the
section 7.1.1.
7.1.2 Stand-alone Unit Set-up
For those of you setting up the monitor using these instructions, it
may be useful for you to follow the steps taken using the Set-Up
Tree.
The philosophy of the instructions is described in section 3.2.
To enter at the top of the Set-Up Tree, press SET-UP and the
monitor displays the following screen text.

7.2 The Measurement Parameters
Sampling
Sampling mode: the manner in which the gases are sampled. There
are two possibilities here:
Continuous sampling: once the monitor is finished measuring it
starts again making the next measurement,
for a full explanation see section 4.1.
Interval Sampling: this is the time from the start of one
measurement cycle to the start of the next
one, for a full explanation see section 4.1.

Flushing: the length of time the monitor flushes the measurement
chamber and the sample tubing between measurements. There are
two options here:
Auto: the monitoring system controls the flushing by
selecting the optimum flushing time. This time can
vary as this option takes into account the
cleanliness of the external air-filters and the
length of the sampling tube.
Therefore, the sample tube length must be defined.
Table 7.4 The acceptable values and the default values of the length of the
sampling tube
Fixed Time: there are two selections here: Chamber, which is
always selected with this option and Tube. See
Table 7.5 for the acceptable values.
Table 7.5 The range of acceptable values and the default values for the
chamber and sample tube flushing times
Water Interference: the Monitor is capable of measuring water’s
contribution to the signal measured in its analysis cell. The user can
decide whether or not the signal should be compensated for water’s
contribution. It is suggested that water should be compensated for in
all measuring situations except where extremely dry gases are being
measure.

Page 78 of 199
Chapter 7
______________________________________________________________________
Cross Interference: if any “interferent” other than water vapour is
present in the ambient air-sample, the Monitor can cross compensate
for the interference caused by its presence provided that a selective
optical filter is installed in the monitor to measure the concentration
of interferent gas present.
Gas
Gas Setup: there are up to six selections here: A, B, C, D, E and W.
These represent the filters installed in the monitor’s filter carousel.
When setting up a new monitoring task, you can choose freely
between the gases available for each filter (names entered when
calibrating the filters, see sections 12.3 and 12.5). Once a gas has
been selected for a filter and the measurement task started, you can
no longer change the gas for this filter in this measurement task.
However, you can still select gases for filters, which have not
previously been used in the measurement task.
Note: only one gas per filter can be selected at a time for
measuring. The W position always represents the water filter
installed in the monitor.
Sample Integration Time: this enables you to make a choice
between speed and accuracy. Generally, the longer the integration
time the more accurate the results. There are several selection
possibilities here:
Integration Type Integration Time
Fast 1 s
Normal 5 s
Low Noise 20 s
Advanced 0.5s, 1s, 2s, 5s, 10s, 20s, 50s
Alarm Set-up
Select Gas: this option enables you to select any of the gases (one
per filter position) already defined in the set-up.
Limit: enables you to define the gas concentration that will trigger
the alarms. The acceptable values are shown in Table 7.6.
Select limits: this defines the concentration level when the alarm
is triggered. This parameter must be defined.

The Monitor’s Display Memory has finite storage capacity. The
data storage time available depends upon the number of gases
being measured, as well as the frequency with which
measurements are performed (that is, the sampling interval).
Section 8.3 provides information about how you can roughly
calculate the length of time the data from a particular monitoring
task can be stored in the Display Memory.
It is important to realise that once the Display Memory has been
filled up by the results of a particular monitoring task, the results
of any further measurements in the same monitoring task will
start to overwrite the data already stored in the memory.

7.3 Setting-up the Monitor’s Alarm Levels
The alarm limits of a gas are those concentrations of gas which
should activate any alarm relay connected to the Monitor via its back
panel “Alarm Relay” socket. There are two different alarm relays,
which function slightly differently. Details of these relays and the way
in which they function is described fully in section 5.5. The alarm
level parameters are found in the Filters branch of the Set-Up Tree.
Warning! If the UA number for any filter is changed here, then all
the calibration data for that filter will be lost and the filter will need
to be recalibrated.

7.4 Starting a Monitoring Task
Monitoring tasks can be started in two ways. They can be started
immediately, or set to start at a pre-set time. The duration of the
monitoring sequence can also be determined. A monitoring task can
continue until it is stopped manually, or at a pre-set time.
When using the PC and the Online option, there are no limits to the
duration of a monitoring task. However, if the measurement results
are being stored in the monitor’s memory, the duration of the
monitoring task should be considered as there is only a finite amount
of memory in the monitor. See section 8.3 for full details about the
storage capacity of the monitor.
7.4.1 PC Use – using the Online Program7810 Application SW
Please refer to user manual BE6027 for Application Software 7810 for
assistance to set-up start and stop a monitoring task.
7.4.2 Stand-alone Use – using the Front Panel Pushbuttons
Before a monitoring task is started, the set-up, as described in
section 7.2, must be completed:
Before any monitoring task is started, all data stored in the Monitor’s
Display Memory is removed (cleared). The Display Memory is where
the Monitor stores the results of all measurements while it is
performing a monitoring task. However, the data in Display Memory
can be copied into and stored in the Monitor’s Background Memory.
This operation is described in section 9.2.
When you start a new monitoring task the following warning is
displayed WARNING: DISPLAY MEMORY WILL BE DELETED to

DATA IN DISPLAY MEMORY RECORDED FROM
2014-01-16 09:50 TO 2014-01-16 10:04
______________________________________________________________________
8.1 Displayed Monitoring Task Data
When the Monitor is switched on, but not being operated in any
mode, the screen display text identifies the data stored in its Display
Memory, by displaying the day and time of the first stored
measurement cycle of the monitoring task, as well as the day and
time of the last measurement cycle of the monitoring task. For
example:
If the Monitor has just been fully reset then the display will just
show the current time and report that the monitor is ready for use.
The Set-up parameters describing a monitoring task and the
measurement data collected during the task are stored as a list in
the Display Memor y. You can scroll through the set-up parameters as
well as the data collected during the task by using the direction
push-buttons, q to scroll “vertically” downwards, and p to scroll
“vertically” upwards through the list. Fig.8.1 illustrates how the data
is organised:
Identification of Measurements:
This screen provides the date and time of the first and last
measurement results, which are stored in Display Memory.
Identification of Each Monitored Gas:
This display identifies the gases monitored during the task. By using
the u push-button, one can find the names of all the gases, which
were monitored during the displayed task.
Statistical Analysis of Measurement Results for Each Gas:
Using the individual measured gas concentration stored in Display
Memory, when Store Measurement History is selected, a statistical
analysis is performed which provides a summary of the stored
measurement results. The MAX (maximum), MIN (minimum) gas
concentrations are displayed, and the µ (Mean or Linear Average)
and σ (Standard Deviation) values are calculated and displayed. A
description of these statistical terms can be found in section 8.2.1.
During the performance of a monitoring task the statistical analysis is
updated constantly.
List of Individual Measurement Results:
Each of these displays provide the date and time each measurement
cycle was performed and the concentration of the gas whose name
appears on the screen. In some cases an asterisk (*) will be shown
alongside the gas/vapour concentration. When such an asterisk is

shown, press the INFO button. Text will appear on the screen to
indicate why this particular measurement has been marked.
The number which is shown on the display – between time and
concentration – is only “filled-in” after completion of a monitoring
task. The number indicates the order in which the measurements
were made. The “oldest” stored measurement is always given the
number 1 and the following measurements are numbered sequentially.
Overview of the Monitoring Task:
These displays provide an overview of the monitoring task set-up
parameters.
Start of the Monitoring Task:
The Display Memory has a finite size and therefore, if a monitoring
task runs for a long period of time, it will fill up all available memory
space, and data collected after the memory has been filled-up will
start to overwrite the data collected during the start of the
monitoring task. Some measurement results will therefore be lost
from the memory. In such a situation the date and time appearing
after MONITORING TASK STARTED….. will not be the same as the
first date and time displayed on the screen labelled 1 in Fig.8.1.

u &t Using these push-buttons users can scroll “horizontally”
through any vertical level of data. For example, if the statistical
analysis of the measurement results for water-vapour are displayed
on the screen, then by using u you can read the statistical analysis
of the measurement results for gas A, B, C etc. and then go back to
the original display (see Fig.8.1).
q This push-button allows the user to scroll
“vertically” downwards through the list of
measurement results (see Fig.8.1).
p This push-button allows the user to scroll
“vertically” upwards through the list of
measurement results. The measurement list is a
closed loop.
The push-buttons p and q have a repetitive function, which means
that if they are pressed continuously they will allow the user to scroll
very quickly through a list.

8.2 Printed Monitoring Task Data
Fig.8.1 illustrates how data from a monitoring task is displayed on
the Monitor’s screen. When monitoring task data appearing in Display
Memory is printed out, the same information appears but it is
presented in a different format. An example of a monitoring task
data print-out is shown in Fig.8.3 – Chapter 10 describes how this is
done.

8.2.1 Statistical Analysis Terms
In the statistical analysis of the measurement results for each gas
(see 3 in Fig.8.1) the following statistics appear:
The Mean Value (µ) – this is the linear average of all
measurements of a gas taken during the total monitoring period.
The calculation of “the mean value” can be expressed
mathematically as follows:
The Mean Value =

8.2.2 Symbols used in Displayed Measurement Data
If an asterisk (*) appears on the display alongside any gas
concentration, it indicates that something happened during the
measurement. You can find out what the asterisk indicates by
pressing the INFO button. The following display appears for a short
period of time:
The symbols which can appear after the text COMMON MARK and
GAS MARK are listed below with a short explanation of what they
mean:
Common Marks:
“P” (1) The Monitor stopped measuring due to a power
failure but has automatically re-started the
monitoring task again after regaining power;
(2) The Monitor has been “reset” either because of
a detected fault or because RESET was pressed.
“O” This symbol indicates that an operational error was
detected during this measurement. The accuracy of
such a measurement cannot always be guaranteed.
_____________________________________________________________________________
BE6030-13 1314i Photoacoustic Gas Monitor LumaSense Technologies A/S
Page 95 of 199
Chapter 8
______________________________________________________________________
“W” This symbol indicates that a warning was detected
during this measurement. The accuracy of such a
measurement cannot always be guaranteed.
Gas Marks:
“B” The Monitor was incapable of calculating this gas
concentration.
“F” After this measurement the filter carousel was
found to be out of alignment. If the carousel was
only slightly out of alignment then the accuracy of
the measurement has not been affected. The accuracy of such a measurement cannot always be
guaranteed.
“A” The gas concentration measured during this
measurement cycle was found to exceed the userdefined alarm limit for this gas.
8.2.3 Symbols Used in Print-outs of Measurement Data
Displayed measurements marked with the COMMON MARKS “O”
and “W”, and the GAS MARKS “A” and ”F”, are printed-out with an
“X” symbol. However, any displayed measurements marked with the
COMMON MARKS “P” and the GAS MARK “B” are not printed-out
with these symbols. These measurements are marked in a different
way:
Common Marks:
The symbol “P” is replaced by the text “1314i Restarted”. This
indicates that the Monitor stopped and then started-up again
sometime between the previous sample time and the time which
appears alongside this message.
Gas Marks:
The symbol “B” is replaced by a straight line (_______) which
indicates that the Monitor was unable to calculate the concentration
of the named gas in this sample.
Other Marks Used:
……This symbol indicates either: (1) that this gas was not measured;
or (2) that this gas was not selected to be printed out (see section
10.5).

8.3 Storage Space in the Display Memory
The total space available in the Display Memory to store data is
131072 measurement cycles. Depending on the time for one
measurement cycle the capacity will be as follows.
If a measurement cycle in which gas A and water vapour are
measured with continuous sampling takes 15s, then the Display
memory space will be 546 hours = 22 days.
If a measurement cycle where 5 gases and water vapour are
measured with continuous sampling takes 60 s, then the Display
memory space will be 2184 hours = 91 days.
The Monitor will overwrite the oldest stored measurement data when
the Display memory is full. This is done by deleting data in blocks of
2048 measurement cycles.
For further information regarding measurement cycles see chapter 4.

______________________________________________________________________
In order to fully understand the functioning of the Monitor it is
necessary to know something about the different types of memory
the Monitor uses, the kind of data stored in each type of memory,
and how this data is affected by the various operations performed by
the Monitor.
Offline users may find the information in this chapter of interest as
their measurement data is stored in the Monitor’s memory before
being uploaded to the PC.
9.1 Types of Memory in the Monitor
The Monitor has three types of memory:
1. A Read Only Memory (ROM);
2. An Electrically Erasable Programmable Read Only Memory
(EEPROM), which we have named the Source Memory;
3. A Random Access Memory (RAM) which we have named the
Working Memory.
9.1.1 Read Only Memory (ROM)
Data stored in this memory cannot be changed by the user. The
Optical Filter Factors, which describe each of the optical filters,
which are available for installation in the Monitor, are stored in this
memory. These factors are listed in a print-out of the “Calibration
Data Block” (see section 10.7).
When optical filters are installed in the carousel wheel, the Monitor
must be informed about:
• Which filters have been installed in its carousel (UA numbers of
the filters);
and
• Where they have been installed (position “A” – “E” of the
carousel – see section 12.3.3).
This information allows the Monitor to read the correct optical filter
factors from its ROM memory when the filter is installed. As these
factors are used in the calculation of calibration factors, it is vitally
important that this information is correctly entered before
calibration is performed.

9.1.2 Source Memory (EEPROM)
The data stored in Source Memory is not lost if A.C. mains power is
removed from the Monitor. There are three blocks of data in the
Source Memory (see Fig.9.1):
Block 1 – contains calibration factors and 3 optical-filter
parameters
Block 2 – contains 3 of the 6 set-up parameters found under the
Filters branch of the set-up “tree”
Block 3 – contains all other parameters in the Set-Up Tree
Block 1 – Calibration Factors and 3 Optical-filter Parameters:
There are six different “data files” in this block. Each data file is
denoted by a letter, which indicates the position a particular optical
filter occupies in the Monitor’s carousel. Each file “A” to “E” is divided
into five sections called Filter Banks, which are numbered from 1 to
5. The water-vapour filter is only capable of measuring water-vapour
and therefore its data file (“W”) is not divided into different filter
banks.
Each Filter Bank contains the following data:
1. The name of the gas used during span calibration of the filter.
2. The molecular weight of the gas used during span calibration.
3. The alarm limits for the gas. (High Alarm Limit 1, High Alarm Limit
2).
4. A Concentration offset factor: obtained during zero-point
calibration of the filter.
5. A Humidity gain factor: obtained during an humidity-
interference calibration of the filter.
6. A Conversion factor: obtained during the span calibration of the
filter with the gas named in point 1 above.
7. Cross-interference calibration factors: obtained during cross-
interference calibration.
