Replacements
Replacement batteries, sensor heads and other accessories can be pur-
chased separately.
Note:
All sensors deteriorate over time. It will be necessary to replace your sensor
head with either a new or refurbished head. This must be done on a sched-
uled basis or when the “sensor aging” or sensor failure” diagnostic appears.
Bump tests, zero and span calibration can be performed under specified
conditions with appropriate tools.

2. About Your Monitor
The Aeroqual Series 300, 305, 500 and 505 Monitors have been spe-
cifically designed to incorporate Aeroqual‟s in-depth knowledge of accu-
rate ambient gas measurement. Different sensor heads are used for
specific gases or depending upon whether high or low concentrations
are to be measured. All the sensor heads are interchangeable on the
same base unit.
The following information details the operation and features of the moni-
tors:
1. The monitors are modular in design and are comprised of two
main components, a Series 300, 305, 500 or 505 monitor, and a
sensor head. This affords the user the ability to replace faulty sen-
sor heads without having to replace the monitor. The monitors can
be mains and/or battery powered and either permanently mounted
or used as portable units.
2. The sensor head is calibrated prior to delivery and does not nor-
mally need to be re-calibrated during its life. (Specific user
guides are supplied for the special operations of particular sensor
heads).
3. The Aeroqual Series 300, 305, 500 and 505 Monitors come with
on-board diagnostics, which will inform the user if the sensor is
not operating correctly.
4. High and low alarms. The high alarm is indicated by flashing
arrows pointing upwards accompanied by a fast beeping sound.
Similarly the low alarm is indicated by flashing arrows pointing
downwards accompanied by a slow beeping sound. This sets
both the monitor and external alarms.
5. Alarm mute. Two alarm mute functions are available, temporary
and permanent mute. Temporary mute is only active during the
specific alarm condition, while permanent mute will remain on until
reset by the user. The alarm arrow indications remain active dur-
ing both temporary and permanent mute.
6. Control. This enables external equipment to be controlled by the
monitor using the high and low control settings, which can be
used to control an external device.
7. Concentration unit selection. The concentration can be dis-
played in either ppm or mg/m3.
8. Min / max / average measurement cycle. The monitor will dis-
play the minimum, maximum, average and 15-minute average
gas concentrations over the measurement period. The Series 305
& 505 will also show temperature and relative humidity in addition
to gas concentration.
9. 0-5V Analogue signal. A proportional voltage output is available
from the external output. The voltage relates to the gas concen-
tration, with 0 V representing 0 concentration and 5 V represent-

5
ing the maximum concentration specified by the range. For ex-
ample, 0 V represents 0 ppm and 5 V representing 0.500 ppm for
the Low Concentration Ozone Sensor Head.
Note: See “Diagnostic Features” on page 42 for output status condi-
tions.
The Series 500 & 505 Monitors offer the following additional fea-
tures:
1. Data logging (on either the Series 500 or 505 Monitor or directly
to a PC). The monitor is able to log up to 8000 data points. The
data can be downloaded to a PC for analysis and record pur-
poses. Data can also be logged directly to a PC via a serial con-
nection while displaying real time data on the PC. The data log-
ging interval can be set in one minute increments from either the
monitor or the PC.
The Series 505 monitor also measures and data logs tem-
perature and relative humidity.
2. Real time clock (24 hr). The clock has a back up clock battery
which will maintain the real time even when all power is lost to
the monitor. Once power is restored data logging will continue if t
he unit was data logging at the time power was lost.
3. PC setup of monitor parameters. All the monitor parameters,
i.e. clock setup, alarm setup, external control setup, logging
setup and concentration units can be set up from the PC.

3.0 Assembly and Installation
Assembly
The following needs to be completed before the Monitor is ready
for use: -
 Insert the sensor head into the top of the monitor. The sen-
sor head is keyed to ensure the head is inserted correctly.
 If the monitor is a mains only unit it is ready for use. If the
monitor is to be used as a portable unit with batteries then
the batteries must be installed and charged prior to use.
3.1 Installing the Battery Pack
 Remove the battery cover from
the monitor.
 Insert the battery power connector
into the monitor power socket in
the back of the monitor.
 Lay the battery cable into the slot
on
the back of the monitor and insert
the tail end of the battery pack into
the hinge points at the bottom of
the monitor back cover.
 Clip the top end of the battery pack
into the top clips, taking note to
orientate the battery pack per the
instructions on the battery pack.
 Replace the battery cover on the
monitor.
Notes on the battery pack

pack, please refer to ‘Battery Information’ on Page 8.

7
Removing the Battery Pack
 Remove the battery cover from the monitor.
 Insert your thumb under the top left hand side of the battery
pack and carefully lever the battery pack out from the retain-
ing clips.
 Unclip the connector from the monitor.
 Replace the battery cover.
Rechargeable Batteries
The Ni-MH (Nickel Metal Hydride) or optional Lithium Polymer bat-
tery pack is used to power the monitor as a portable unit. Please
read the following information carefully before using the battery pack
to operate the Aeroqual monitor.
Safety
 Do not use the battery pack for any other purpose than oper-
ating the Aeroqual monitor
 Do not disassemble or mutilate the batteries as this may
cause burns
 Do not incinerate or heat as this may cause burns, the batter-
ies may burst or cause the release of toxic materials
 Do not short circuit as this may cause burns
 Use only batteries approved by Aeroqual and recharge your
battery only with the AC/DC adaptors supplied by Aeroqual.
 Never use any charger or battery that is damaged or worn
out.
 Batteries must be recycled or disposed of properly. They
must not be disposed of in municipal waste.
 Never charge the battery in a hermitically sealed container.
Using the battery pack
The life of the battery pack will be affected by the way it is handled.
Take good care of the battery pack and follow the guidelines sug-
gested in the following section.

Charging and Discharging the Batteries
Ni-MH batteries
Ni-MH batteries must be fully charged prior to first-time use. A new Ni-MH
battery's full performance is achieved only after a number of complete
charge and discharge cycles. A fully charged battery will run for approxi-
mately 4-6 hours depending on the sensor head being used.
Charging Instructions
With the adaptor plugged in allow 15 hours for the battery to fully charge.
Note 1:
 During charging the battery symbol on the display flashes slowly.
 The battery can be charged with the sensor head installed or removed
from the base. (Remember to switch off the monitor before removing
the sensor head).
 Unplugging the main power will reset the above charging conditions.
 The batteries can be charged and discharged many times but will even-
tually wear out. When the operating time is noticeably shorter than nor-
mal, it is time to replace the batteries.
 It is not necessary to fully discharge the batteries. When not using the
Series 300, 305, 500 or 505 Monitor as a portable unit, always plug in
the mains adaptor to recharge the batteries.
 If left unused a fully charged battery will discharge itself over time.
Note 2:
If you have difficulty charging the battery, either:
A) Replace the battery
B) Contact Aeroqual with the software version number
(see section 3.3 to locate the version number.)
Additional Information for Lithium Polymer Batteries
A new battery's full performance is achieved only after a number of com-
plete charge and discharge cycles. A fully charged battery will run for ap-
proximately 10 hours depending on the sensor head being used.
Charging Instructions
 With the adaptor plugged in allow 3 hours for the battery to fully charge.
 There is no battery symbol on the display when using a lithium battery.
 The battery can be charged with the sensor head installed or removed
from the base. (Remember to switch off the monitor before removing
the sensor head).
 The Lithium Smart Charger displays a red LED light when charging
and a green LED light when the battery is charged.

9
Installing the AC/DC adaptor
 Connect the AC/DC adaptor to the mains supply. Ensure that
the adaptor is correctly rated for the power supply.
 Plug the adaptor into the monitor. The monitor can now be
used as a mains unit. If the monitor is to be used as a port-
able unit the batteries will need to be charged.
3.2 Sensor warm up
Prior to operation the monitor must be warmed up to burn off
contaminants on the sensor. When the monitor is first switched
on it will warm up for 3 minutes. Then the reading will flash for
the next 7 minutes to indicate that the sensor is still in the warm
up phase. It is recommended that the monitor is kept in Stand By
mode when not being used to keep the sensor heated and
prevent the build up of contaminants. If the sensor is new (or
unused for long periods) it can take up to 24 hours for the
message “sensor warming up” (or “sensor failure” in older
models) to disappear. Should the message remain after this time,
a genuine sensor failure may have occurred. See the trouble-
shooting guide.
24hrs is a conservative time for an ozone sensor to burn off con-
taminants and achieve its stated performance specification. In
most instances this will be achieved well within 24hrs.
Since O3 is an oxidising gas the warm up period can be reduced
by subjecting the sensor to elevated O3 levels for a short period.
For example, 100 ppb of O3 for 5 minutes typically reduces the
warm up time to 30 minutes.
Warning: Do not remove the sensor head while the monitor
is switched on. This may damage the unit. If the sensor head is
removed under these conditions, the unit will automatically shut
down.
3.3 Monitor and Sensor Versions
Turning the monitor on will display “AEROQUAL MONITOR
S300 / S305 / S500 / S505 V x.x”, where "V x.x" represents
the version of the monitor base. The display will then show
“SV6.0”or similar, which indicates the software version installed
on the sensor head

4. Operating Instructions
The following instructions detail the operation and set up of the
monitor.
4.1 Turning the monitor on and off
To turn the monitor on, press & hold the power button until
the screen activates. The monitor will turn on and the display
will show “AEROQUAL MONITOR S300 / S305 / S500 / S505

4.2 Turning Standby Mode on and off
To activate Standby Mode with the monitor on, press the power
button once. This will stop operation of the monitor; however the
sensor will be kept warm. This mode is used to conserve power
between operations but keep the sensor ready to measure the
gas concentration with only a short warm up phase as described
in “Warm up” in section 3.2. In this mode the display will be as
shown below:
To return the monitor to operational mode press the power but-
ton once.
NOTE: When using a Carbon Dioxide sensor head in
standby mode, the sensor runs at full power and the fan
remains on.
4.3 Operating under Battery power
A battery indicator will appear at the bottom of the display when
the monitor is operating under battery power only. The indicator
shows the battery life remaining.
4.4 Sensor Head Failure
There are two possible Sensor failure modes, which will be
indicated by one of the following messages on the display: -
“Sensor Failure, Replace sensor” –The sensor head should
be replaced as this indicates that there has been component
failure.
“Sensor aging”:- This indicates that the sensor has reached
the end of its usable life and the sensor head should be replaced
as soon as possible. The measurement readings can no longer
be relied upon to be within specification.

To access the calibration menu, scroll down and hold and
simultaneously for approximately 2 seconds. Once the calibration menu
has been entered, users can select „ZERO CAL‟ or „SPAN CAL‟.
4.61 Zero Calibration
The “ZERO CAL” routine resets the zero point of the monitor.
This routine must be conducted under controlled conditions:
 Minimum 24 hours warm up
 Clean air (charcoal filtered is best), no cross-sensitive gases
 Stable and low air flow around the monitor
 No vibration or movement of the monitor
 Temperature at 20°C ±2°C (68°F ±3.5°F)
 Relative Humidity of 50% ±5%
An incorrect "ZERO CAL" does not cause permanent damage.
The process should be repeated under the above conditions.
NOTE: Carbon Dioxide sensors MUST be calibrated in a certi-
fied Zero Air environment. If in doubt contact Aeroqual Limited.
Press and hold until the word GO appears next to Reset
Routine. The routine will run for up to ten minutes (depending on
the gas sensor installed) and then beep to indicate completion.
Talk to your supplier or distributor if you have questions.
 See section 11.9 for more information
4.62 Span Calibration
