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

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.

Sensor Heads
Outlet
Inlet (meshed)
Keyed connector to ensure
inserted correctly into base
Note: Always place the sensor head perpendicular to the air flow to avoid damage to the
sensor.
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.

5. External Control Wiring (Model 2750)
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
Kanomax Gasmaster User Guide
MRK-D-0002 V3
Page | 18
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 Kanomax 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.
Kanomax Gasmaster 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 ranges. For example: With the low
concentration ozone sensor head: 0 V represents 0 ppm ozone and 5 V represents 0.Model 2750
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 Kanomax and purchase a replacement sensor
with a multi-point calibration and new calibration certificate.
2. Manual calibration. The easy calibration procedure is outlined below. Kanomax supplies a
Calibration 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 Accessory
•
Inert tubing (Regulator to gas inlet) See table for gas/material compatibility
•
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
1. Charge R42 Calibration Gas Accessory with 5g of water with water syringe via water inlet.
2. Fit cylinder and regulator to R42 gas inlet via tubing and Luer attachment.
3. Place warmed up Kanomax sensor head in R42 outlet as shown below. The Kanomax sensor
head is now ready for zero or span calibration.
Note: The inlet of the sensor head should be inserted into the outlet of the R42 (the inlet of the
sensor head has a mesh cover)
Note: The MS1 and MS2 multi-sensor heads require that the sensor head be inserted in
different positions depending on the sensors being calibrated.

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 Kanomax Gasmaster by:
•
Model 2710: 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.
•
Model 2750: : 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 Model 2710 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.
6.3.
Span Calibration
Span calibration is only available on the Model 2750. It provides an option to adjust the GAIN of
Kanomax sensor heads. There are no optimum span concentrations for calibrating Kanomax sensor
heads. There are however a few considerations which can guide the decision as to which span
concentration is most appropriate.
Kanomax Gasmaster User Guide
MRK-D-0002 V3
Page | 22
For the majority of uses, gases will be purchased for calibration at the concentration to be used for the
span calibration, rather than purchased at high concentrations and later diluted using a gas dilution
calibrator. Therefore users may find some restrictions on what concentrations can be provided by
their chosen calibration gas supplier.
For some applications measurements will be made close to the monitor’s maximum detection limit.
For these applications a span point at 80 % of full scale is suggested. For other applications, gas
levels may be important across a broad range rather than just close to the maximum exposure limit.
Other applications may make more use of the lower end of the sensors working range, with higher
levels occurring less frequently and having less importance. The most appropriate span point will thus
depend upon the intended application. If the intended application is not known, Kanomax suggests a
span point at 80 % of full scale. All gases should be purchased in a balance of air.

6.3.1. Procedure
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 Kanomax 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.
6.4.
Bump Test
Operators may wish to have increased confidence in the operation of their monitor by performing a
bump test prior to taking measurements.
A bump test involves quickly exposing the sensor to span gas and confirming the sensor indicates an
elevated response. The equipment for performing a bump test is the same as for performing a span
calibration, however it is not necessary to wait for the monitor to warm up before performing a bump
test, nor is it necessary to wait for the monitor readings to stabilize to confirm a successful bump test.
Turn on the monitor and place it at the outlet of the R42, you will need to wait three minutes before
readings will be displayed on the monitor. Turn on the span gas and observe the sensor reading, the
reading should quickly elevate above the baseline reading and approach that of the span gas
concentration. If the reading does not approach that of the span concentration this could indicate a
monitor fault or the need to perform a calibration. Once an elevated reading has been observed close
to the span gas concentration the gas can turned off, you must then wait for the readings to come
down to baseline level before taking measurements.
6.5.
Health and safety during calibration
Upmost care must be taken while performing a zero or span calibration. Cylinder gas can cause harm
in a number of ways. There a number of sources of good information about the correct use and
storage of compressed gases.
The following resources may prove useful:
The National Institute for Occupational Safety and Health
Kanomax Gasmaster User Guide
MRK-D-0002 V3
Page | 24
http://www.cdc.gov/NIOSH/
The United States Department of Labour
http://www.osha.gov/SLTC/compressedgasequipment/index.html
The following information is a guide for what to consider when handling compressed gas but
Kanomax recommends operators adhere to their local regulations regarding compressed gas
handling.
6.5.1. High pressure leak or failure of pressure regulator
Many calibration gases are held in cylinders at high pressure in excess of 1000 Psi. Incorrectly fitting
the pressure regulator, using a regulator which is faulty or knocking the cylinder over while the
regulator is attached can cause physical harm from high speed projectiles resulting from a high
pressure leak from or failure of the regulator.
•
It is important to always fit a high quality undamaged pressure regulator to the gas cylinder
and that the regulator type is suitable for the cylinder you are attaching it to.
•
Always use protective eyewear (safety glasses) when working with compressed gas.
•
Always point the cylinder and regulator away from yourself and others when attaching or
removing the pressure regulator.
•
Always secure the cylinder to prevent it from being knocked over while the regulator is
attached.
6.5.2. Flammability of combustible gases
Calibration gas can be stored in cylinders at high concentrations and can this can present a hazard if
those gases are combustible. The lower explosive limit (LEL) is the lowest concentration of gas at
which combustion will be sustained in air if an ignition source (spark or flame) is present. The LELs for
the gases used for calibrating Kanomax sensor heads are all significantly above the calibration span
points so this risk is low. It is important however that the LEL be known for the gas being employed
and that suitable precautions be taken to further minimize the risk from explosive combustion such as
performing the calibration in a fume hood. Table XX lists the LELs for the gases used to calibrate
Kanomax’s sensor heads.
6.5.3. Toxicity
While most of the recommend span points fall below the Immediately Dangerous to Life or Health
(IDLH) limits published by the National Institute for Occupational Health and Safety (NIOSH), some
span points are above these limits and therefore it is crucial that rigorous health and safety
procedures be followed during calibration to avoid exposure to the calibration gas.
The table below lists the IDLH concentration limits as well as concentration limits for longer exposure
times. The LDLH limits are known for most of the gases of concern, however there are some gases
for which data are not available. In these cases gases should be considered as being toxic and
handled as such. Health and safety data are often revised, Kanomax recommends checking external
sources for the most up to date information. Kanomax suggests that all span calibrations be
performed in a fume hood such as the one in the image below to avoid exposure to personal.

9. Guidelines on How to Measure Ozone
The following information is presented to help users operate their Kanomax Gasmaster 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 Kanomax 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 Kanomax 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.
