KANE-ALERT-CO2
Monitor
with Temperature
Operating Instructions

This is a portable, handheld carbon dioxide (CO2)monitor using NDIR
technology to provide long term stability. It also measures ambient temperature.
The monitor also has the following features:
;Data logger stores 48 sets of CO2and temperature readings in the last 24
hours - one log every 30 minutes.
;Max/Min mode records the maximum and minimum concentrations of
CO2since the monitor was switched on.
;Alarm mode sounds at 1000 PPM (the ASHRAE limit) and can be turned
off.
;RCFS Mode recovers original factory settings after the monitor is
recalibrated.

MODE FUNCTIONS
The monitor has several Modes which can be adjusted. In sequence these modes
are Alti Mode, Alarm Mode, Outside Mode, Cali Mode, Datalogger Mode,
MaxMin Mode and rcFS Mode.
ALTI
Compensates for changes in
atmospheric pressure due to
altitude or weather conditions.
ALARM
Alarms when CO2 concentration
exceeds 1000 ppm. Alarm
sounder can be switched on or
off.
OUTSIDE
Modifies the outside CO2
concentration. The factory
nominal setting is 400 ppm.
CALI
Allows trained service personnel
to recalibrate the sensor. Take
care using this function as errors
can be created.
DATALOGGER
Shows CO2and temperature
records over the last 24 hours.
Reading No. 1 is the most recent.
Reading No. 48 is the oldest.
MaxMin
Shows Max and Min CO2
readings since last being
switched on. These readings are
cleared every time the device is
switched off.
rcFS
Recovers the factory setting.

OPERATION INSTRUCTIONS
Power On
Press Power button (1) to turn on the monitor after placing 4 AA batteries
into the battery compartment (take care to observe correct polarity) or AC
adapter plug into the DC socket. CO2 readings will show after 15 seconds of
warm up.
WarmUp
This lasts approximately 1 min before WARMUP disappears; none of the
functions will respond during warm up.
Normal Operation
After warm up, the monitor stabilizes and displays CO2 readings on its Upper
Display which remain visible at all times.
Temp and Ventilation Rates (Lower Display)
Use the Up/Down button to scroll through Temperature and Ventilation
Modes.
When pressing the Up button, the lower display goes through the following
sequence:
Temp °C-> Temp°F-> Vent Rates lps-> Vent Rate cfm/p
*Note: lps refers to Litres Per Second Per Person;
cfm/p refers to Cubic Feet Per Minute Per Person
This function assumes that each person exhales 300 cc of CO2every minute
and calculates the rate of ventilation of external air required to achieve
equilibrium at the measured CO2level.

Adjusting Modes
1. ALTI Mode – Setting the altitude at which you are using the monitor
1.1. Press Mode until ALTI flashes
1.2. Press Mode to alter between m (meters) and ft (feet)
1.3. Press Up/Down to adjust the altitude (Step=100m/500ft)
1.4 Press Enter to save the setting or leave the ALTI Mode, return to
UserMode.
2. ALARM Mode – Switching On or Off the Audible Alarm
2.1. Press Mode until ALARM flashes
2.2. Press Enter until ALARM “speaker icon” flashes
Press Up/Down to turn the ALARM On or Off
2.3. Press Enter to save the setting and return to UserMode.
3. OUTSIDE Mode – Setting the outside level of CO2if known
**Note: Ventilation Rate
Ventilation rate represents how much air is introduced into the indoor space
from the outside. Low levels indicate low ventilation rates and potentially
poor air quality. High levels indicate excessive ventilation and potential
excessive energy usage. To obtain an accurate measurement, readings
should be taken 2~3 hours after occupancy has stabilized in a space or
at a peak in daily CO2concentrations.
In indoor air quality control, CO2 value is an indicator of ventilation rate.
400ppm (Parts Per Million) is the default CO2concentration outside
(according to ASHRAE: American Society of Heating, Refrigeration and
Air-conditioning Engineers).
3.1. Press Mode until OUTSIDE flashes
3.2. Press Enter until OUTSIDE, CO2and PPM flash
Press Up/Down to adjust the reading
3.3. Press Enter to save the setting and return to UserMode
After modification, the VENT Rate will change.

4. CALI Mode – Recalibrating the CO2sensor
4.1. The monitor is pre-calibrated in the factory and should only be
recalibrated with a certified test gas in a controlled test chamber. This
mode should only be accessed by trained service personnel.
5. DATA LOGGER Mode – Viewing data recorded over the previous 24
hours
The monitor’s internal Datalogger records CO2and temperature readings
every 30 minutes over the past 24 hours.
5.1. Press Mode until DATALOGGER flashes
5.2. Press Enter until CO2and Temperature are displayed
Press Up/Down to PAGE UP/DOWN readings
5.3. Press Enter to return to UserMode
6. MaxMin Mode – Viewing Maximum and Minimum values
The monitor’s MaxMin Mode displays the maximum and minimum CO2
readings since the monitor was last switched on.
6.1. Press Mode until MAX MIN flashes
6.2. Press Enter to alternate between MAX and MIN CO2readings
6.3. To clear the memory, press UP or DOWN until “CLR” flashes.
Press Enter to CLEAR the MAX and MIN record
6.4. Press Mode or Enter to return to UserMode
7. rcFSMode
If the CO2sensor is incorrectly re-calibrated, the monitor’s factory setting
can be recovered.
7.1. Press Mode until rcFS flashes on the lower display
7.2. Press Enter until “no” shows on the upper display
7.3. Press Up/Down to change to “yes”
Press Enter, Factory Setting will reload
7.4. Press Mode to return to UserMode

ELECTROMAGNETIC COMPATIBILITY
European Council Directive 89/336/EEC requires electronic equipment not to
generate electromagnetic disturbances exceeding defined levels and have
adequate immunity levels for normal operation. Specific standards applicable to
this analyser are stated below.
As there are electrical products in use pre-dating this Directive, they may emit
excess electromagnetic radiation levels and, occasionally, it may be appropriate
to check the analyser before use by:
Use the normal start up sequence in the location where the analyser will
be used.
Switch on all localized electrical equipment capable of causing
interference.
Check all readings are as expected. A level of disturbance is acceptable.
If not acceptable, adjust the analyser’s position to minimize interference
or switch off, if possible, the offending equipment during your test.
At the time of writing this manual (Nov 2007) Kane International Ltd are not
aware of any field based situation where such interference has occurred and this
advice is only given to satisfy the requirements of the Directive.
This product has been tested for
compliance with the following generic
standards:
EN 61000-6-3
EN 61000-6-1
and is certified to be compliant
Specification EC/EMC/KI/ALERT-CO2
details the specific test configuration,
performance and conditions of use.
Please Note:
Batteries used in this instrument should be disposed of in accordance with
current legislation and local guidelines.
At the end of the product's life it should be re-cycled in accordance with current
legislation and local guidelines.

ANNUAL RECALIBRATION AND SERVICE
There are no user serviceable components in this product.
Although sensor life is typically more than five years the analyser should be re-
calibrated and serviced annually to correct for any long-term sensor or
electronics drift or accidental damage.
Local regulations may require more frequent re-calibration.
APPENDIX
Recommended Carbon Dioxide Levels:
British Standards BS6896, BS6230 and BS5990 confirm CO2
concentration should not exceed 2800ppm where people are working.
HSE Regulation EH40 sets the maximum occupational exposure limit
at 5000ppm.
BSRIA recommend a maximum of 800ppm over an eight hour time
weighted average.
ASHRAE (62/99) recommends a maximum level of 1000ppm.
