Kane ALERT-CO2 Operating Instructions Manual

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 CO

2

and temperature readings in the last 24

hours - one log every 30 minutes.

; Max/Min mode records the maximum and minimum concentrations of

CO

2

since 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.

(Display Features and Modes)

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 CO

2

concentration
exceeds 1000 ppm. Alarm
sounder can be switched on or
off.

OUTSIDE

Modifies the outside CO

2

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 CO

2

and 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 CO

2

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. CO

2

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 CO

2

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 CO

2

every minute
and calculates the rate of ventilation of external air required to achieve
equilibrium at the measured CO

2

level.

 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 CO

2

if 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 CO

2

concentrations.

In indoor air quality control, CO

2

value is an indicator of ventilation rate.

400ppm (Parts Per Million) is the default CO

2

concentration 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, CO

2

and 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 CO2 sensor

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 CO

2

and temperature readings

every 30 minutes over the past 24 hours.

5.1. Press Mode until DATALOGGER flashes

5.2. Press Enter until CO

2

and 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 CO

2

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 CO

2

readings

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 CO

2

sensor 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 re­calibrated 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 CO

2

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.
