The life of the battery will be affected by the way it is handled. Take good care of the battery pack and
follow the guideline below.
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 approximately 4-6 hours depending on the sensor head being used.
Page | 5
Aeroqual Series 200, 300 & 500 User Guide
With the adaptor plugged in and unit turned on allow 15 hours for the battery to fully
charge.
•
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 eventually wear out
When the operating time is noticeably shorter than normal, it is time to replace the battery
•
It is not necessary to fully discharge the battery. When not using the monitor as a portable
unit, always plug in the mains adaptor to recharge the battery
•
If left unused a fully charged battery will discharge itself over time
2.1.4. Charging Lithium Polymer Batteries
A new battery's full performance is achieved only after a number of complete charge and discharge
cycles. A fully charged battery will run for approximately 8 hours depending on the sensor head
o
o
being used. Perform charging at temperatures between 0 C to 45 C.
With the adaptor plugged in and unit turned off allow 3 hours for the battery to fully charge.
•
Lithium versions show “Lithium Battery” on the initial monitor start up screen.
•
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 when monitor is off.
Note: The unit can be charged when switched on but it will charge more slowly. When the
unit is operating the red LED will remain on, even if the battery is fully changed.

2.2. Sensor Heads
2.2.1. Sensor Warm Up
Prior to operation the sensor must be warmed up to burn off any contaminants. When the monitor is
first switched on it will warm up for 3 minutes. The reading will then 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.
For Ozone Sensor Heads:
•
24hours is a conservative time for an ozone sensor to burn off contaminants and achieve its
stated performance specification. In most instances this will be achieved well within 24hrs.
•
The warm up period can be reduced by subjecting the sensor to elevated ozone levels for a
short period. For example, 0.1 ppm of ozone for 5 minutes typically reduces the warm up time
to <30 minutes.
Note: 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 without AC/DC adapter connected,
the unit will automatically shut down.
2.2.2. Sensor Head Failure
There are three 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.
Note: This message will only apply for O3 Low/Ultra Low sensor heads.
“S.F.” – When there is more than one sensor connected, S.F. will show for a sensor failure condition.
2.3. Optional Temperature and Relative Humidity Sensor
If the temperature and relative humidity sensor has been purchased, it can be inserted into the PS/2
connector at the base of the monitor. Ensure monitor is turned off before connecting the sensor.

5. External Control Wiring (Series 300 & 500)
The pin numbers for the external output connector are numbered from 1 to 6. Pin 1 is the closest pin
to the power jack.
The pin designations are as follows:
1. 12 V DC
2. Analogue output 0-5 V
3. Control
4. High alarm
5. Low alarm
6. Ground
Page | 18
Aeroqual Series 200, 300 & 500 User Guide
The RJ12 connector offers two possibilities for wiring, either a switch to GND or a 12V output. If the
12V output is used, the power for the relay coil is supplied by the Aeroqual AC/DC adaptor. In this
case, ensure that the relay coil does not draw more than 150mA and that a protection diode is
inserted across the relay coil.
If the switch to GND output is used, ensure that the relay coil does not draw more than 150mA, that
the voltage does not exceed 24V and that a protection diode is inserted across the relay coil.
5.1. Wiring for Alarm
The high alarm and low alarm pins can be wired to supply simple on / off switching to operate
equipment which requires only an on or off signal, such as an alarm.
To switch to GND use pins 4, 5 and 6. For a 12V output wire to pins 4, 5 and 1 (see the following
diagram for typical wiring for high alarm). This feature will only operate while powered by the AC
adaptor.
High gas level alarm
Note: Failure to insert a circuit protection diode, shown as above, will result in damage to the
monitor if a voltage spike is created by the relay.
5.2. Wiring for Control
The control pin can be wired to supply control of a gas concentration between upper and lower
concentration limits. The upper and lower limits can be set by the user. The factory default settings
are dependent on the gas sensor head selected at time of purchase.
To switch to GND use pins 3 and 6. For a 12V output wire to pins 3 and 1 (see following diagram for
typical wiring). This feature will only operate while powered by the AC adaptor.
Control is achieved by using a software latch. If power is lost to the monitor, the switch will open and
therefore turn off the external device connected to the monitor external output. The following wiring
diagram demonstrates the typical wiring to achieve the required control.
Page | 19
Aeroqual Series 200, 300 & 500 User Guide
Note: Failure to insert a circuit protection diode, shown as above, will result in damage to the
monitor if a voltage spike is created by the relay.
5.3. Wiring the 0-5 V Analogue Output
The 0 to 5 V signal is a proportional signal based on the measurement of the selected output sensor.
The voltage out spans the specified gas sensor concentration range. For example: With the low
concentration ozone sensor head: 0 V represents 0 ppm ozone and 5 V represents 0.500 ppm ozone.
Note: The ultra-low ozone sensor is a special case – 1.5V represents 0.150ppm ozone in this
case.
Note: Wire between pins 2 & 6
See Section 7.1 for output status conditions.
6. Calibration of Sensor Heads
Sensor heads can be calibrated in two ways:
1. Via replacement. Return your sensor head to Aeroqual and purchase a refurbished sensor
with a multi-point calibration and new calibration certificate.
2. Manual calibration. The easy calibration procedure is outlined below. Aeroqual supplies a
calibration humidifier accessory (R42) to facilitate humidity control and delivery of calibration
gas to the sensor head.
6.1. Calibration Procedure
In order to calibrate successfully the following equipment is needed:
•
R42 Calibration Gas Humidifier
•
Teflon tubing (Regulator to gas inlet)
•
0.5 LPM constant flow regulator (eg Calgaz regulator model 715, flow rate 0.5 LPM)
•
Span gas in air cylinder
•
Zero grade air cylinder
Page | 20
Aeroqual Series 200, 300 & 500 User Guide
1. Charge R42 Calibration Gas Humidifier with 5g of water with water syringe via water inlet.
2. Fit cylinder and regulator to R42 gas inlet via Teflon tubing and Luer attachment.
3. Place warmed up Aeroqual sensor head in R42 outlet as shown below. The Aeroqual sensor
head is now ready for zero or span calibration.

6.2. Zero Calibration
Under some circumstances the sensors may temporarily exhibit a baseline reading higher than zero
due to insufficient warm up or cross-sensitivity to other gases. In this case it is also worthwhile
checking against a standard zero air source.
1. Follow the initial set up instructions in 6.1
2. Flow zero air until the reading stabilises (about 10 minutes)
3.
Initiate Zero Calibration on the Aeroqual Monitor by:
•
Series 200: Press and hold the “enter” button until the word “Zeroing” appears next to
ZERO CAL. The routine will run for up to ten minutes (depending on the gas sensor
installed) and then beep to indicate completion.
•
Series 300 and 500: : Enter the CALIBRATE menu by pressing the “mute” and “scroll
down” buttons for 2 seconds. From here select “ZERO CAL” then:
o
Single gas heads: Toggle YES/NO using scroll button to YES then press enter.
The word “Zeroing” appears and the zero routine will run for up to ten minutes
(depending on the gas sensor installed) and then beep to indicate completion.
o
Multi-gas sensor heads and T/RH probe: Press enter to bring up the OFFSET
for the Sensor head. Use the scroll buttons to change the OFFSET and enter
button to accept. Calculate the new OFFSET using the equation below:
New OFFSET = Sensor Reading/GAIN + old OFFSET
Note 1: The Series 200 can only zero calibrate single gas sensors.
Note 2: Temp/RH offsets are stored on the handheld rather than on the sensor. All other
offsets are stored on the sensors.
Page | 21
Aeroqual Series 200, 300 & 500 User Guide
6.3. Span Calibration
Span calibration is only available on the Series 300 and 500. It provides an option to adjust the GAIN
of Aeroqual sensor heads.
Recommended span concentrations for some Aeroqual sensor heads is given in the table below:
Aeroqual Sensor Head
Carbon Monoxide 0-100 ppm
Carbon Monoxide 0-1000 ppm (leak)
Carbon Dioxide 0-2000 ppm
Carbon Dioxide 0-5000 ppm
Nitrogen Dioxide 0-1 ppm
NH3 0-100ppm
NH3 0-1000ppm (leak)
Hydrogen 0-5000 ppm
H2S 0-10 ppm
H2S 0-50 ppm
Methane 0-10000 ppm
Ozone (low or ultralow)
PERC 0-200 ppm

1. Follow the initial set up instructions in section 6.1
2. Flow the target gas at 0.5 LPM
3. Measure the gas concentration on the monitor screen and wait for it to stabilise (10 minutes).
4. If the Aeroqual sensor head requires a span adjustment then enter the CALIBRATE menu by
pressing the “mute” and “scroll down” buttons simultaneously for 2 seconds. Then select
SPAN CAL and change the GAIN using the scroll buttons. Calculate the new GAIN using the
equation below:
New GAIN = Old GAIN x Span Gas Concentration (ppm) / Sensor Reading
Note 1: Temp/RH GAINs are stored on the handheld rather than on sensor. All other GAINs are
stored on the sensors.

9. Guidelines on How to Measure Ozone
The following information is presented to help users operate their Aeroqual monitor with an ozone
sensor installed in the most effective and efficient manner.
General
•
Ozone is heavier than air and tends to sink. Thus detection of leaks from ozone generating
equipment should be performed at the most appropriate position.
•
Ozone will react and decompose on surfaces such as walls, furniture etc.
•
Smell is not a reliable test for the presence or concentration of ozone as the odour
threshold varies widely between people and is affected by local ambient conditions.
Permanent Controller Placement
•
The Aeroqual Ozone Controller has been designed to measure the ambient concentration
of ozone. The controller must not be placed directly in an ozone stream.
•
For indoor local area monitoring attach the controller to an inert surface with the inlet
unobstructed.
•
For leak detection mount the unit near the ozone equipment.
•
Ensure that the controller is protected from excessive water splashing, dust, vibration,
excessive heat or cold, high concentrations of ozone and excessive swings in humidity.
False Readings
•
The Aeroqual Ozone Controller has been designed to respond selectively to ozone.
However, other oxidizing gases such as chlorine and nitrogen dioxide can generate false
readings if they are at high concentrations. High concentrations of hydrocarbon gases
such as vapours of alcohol, oils and solvents can reduce and mask the concentration of
ozone.
10.
Care and Maintenance
Your Aeroqual Monitor is a product of superior design and quality and should be treated with care.
When using your Aeroqual Monitor:
•
Keep it and all its parts and accessories out of the reach of small children.
•
Keep it dry. Avoid water and/or condensation as humidity and liquids may damage sensitive
electronics and the Li battery.
•
Do not use or store in dusty, dirty areas.
•
Do not store the monitor in temperatures below 10°C or above 35°C.
•
This unit is designed for use at temperatures between -5°C and +45°C however please consult
recommended operating temperature for the sensor head which may be different. Avoid sudden
changes in temperature which may cause condensation that can damage the electronics.
Page | 28
Aeroqual Series 200, 300 & 500 User Guide
•
Do not attempt to open. Non-expert handling of the device may cause damage.
•
Do not drop, knock or shake as this could lead to internal damage.
•
Do not use harsh chemicals, cleaning solvents or strong detergents for cleaning. Wipe with a soft
cloth slightly dampened with a mild soap-and-water solution
In order to maintain measurement accuracy, Aeroqual recommends that user replace or
refurbish their sensor heads on a yearly basis or more often if measurement certainty is
critical for your application. Please contact your dealer or Aeroqual.
