4.0 Calibration

4.1 On initial start up with a new sensor, allow the unit to stabilize for

about 10 minutes before proceeding to the next step.

4.2 With the chuck exposed to air, press and hold ( ) key down until

the LCD starts to count down from 3 to 0. Release the ( ) key and

wait for the LCD to read 79.1 (calibration point) plus or minus 0.1.

Excluding factors such as temperature,humidity and traces of other

gases, the air we breathe contains 78.084% Nitrogen, 20.946%

Oxygen, 0.934% Argon and 0.033% Carbon Dioxide.

Note : Excess Nitrogen in the sensing head during calibration will lead to

low readings during sampling. For best results, calibrate the

instrument each day before sampling begins. This will ensure the

sensing head is exposed to air for accurate calibration. If calibration

is needed during normal use, leave the sensing head exposed to

air for about 10 minutes or until the readings stabilize before

commencing with the calibration.

5.0 Gas Sampling

Press and hold chuck onto the valve stem and allow the gas to flow until a

stable reading is achieved. Depending on the tire pressure, sample time is

about 10 seconds. Repeat the sampling process as needed.

Note : It is not necessary for the reading to return to the calibration point

(79.1) between samples.

6.0 Turning the unit OFF

To switch off immediately, press and hold the ( ) key for 1 second, then

release the ( ) key. To extend battery life, the unit has an auto-off

function after 5 minutes.

7.0 Freezing of Gas Sampling Reading

To freeze the gas sampling reading, make a quick press and release the ( )

key. When the reading is put on freeze, the display will flash. To resume the gas

sampling, make another quick press and release the ( ) key. The display will

stop flashing, showing the corresponding gas reading.

Health Hazard Data

Routes of Entry :

Acute Effects :

Chronic Effects:

Inhalation : Highly unlikely.

Ingestion : May be fatal if allowed.

Skin : The electrolyte (potassium hydroxide) is corrosive;

skin contact may cause irritation or severe chemical burns.

Eyes : The electrolyte (potassium hydroxide) is corrosive;

skin contact may cause irritation or severe chemical burns.

The electrolyte is harmful if swallowed, inhaled or absorbed

through the skin. It is extremely destructive to tissue of the

mucous membranes, stomach, mouth, upper respiratory

tract, eyes and skin.

Prolonged exposure with the electrolyte has a destructive

effect on tissue.

Chronic exposure to lead may cause disease of the blood

and blood forming organs, kidneys and liver, damage to

the reproductive systems and decrease in fertility in men

and women, and damage to the foetus of a pregnant

woman. Chronic exposure from the lead contained in this

product is extremely unlikely.

10.0 Material Safety Data Sheet

www.airtecasia.com

Signs and Symptons of

Exposure :

Carcinogenicity :

OSHA:

NTP

Medical Conditions

Generally Aggravated

by Exposure :

Contact of electrolyte with skin or eyes will cause a burning

sensation and/or feel soapy or slippery to touch.

Other symptons of exposure to lead include loss of sleep,

loss of appetite, metallic taste and fatigue. For additional

exposure information, refer to 29 CFR 1910.1025,

Appendix A - Substance Data Sheet for Occupational

Exposure to Lead.

Lead is classified by the IARC as a class 2B carcinogen

(possibly carcinogenic to humans).

Where airborne lead exposures exceed the OSHA action

level, refer to OSHA Lead Standard 1910.1025

Lead exposure may aggravate disease of the blood and

blood forming organs, hypertension, kidneys, nervous and

possibly reproductive systems. Those with pre-existing skin

disorders or eye problems may be more susceptible to the

effects of the electrolyte.

Emergency First Aid Procedures

In case of contact with the skin or eyes, immediately flush with plenty of water for at

least 15 minutes and remove all contaminated clothing. Get medical attention

immediately.

If ingested, give large amounts of water and DO NOT INDUCE VOMITING. Obtain

medical attention immediately.

If inhaled, remove to fresh air and obtain medical attention immediately.

of the sensors do not present a health hazard. The following information is given

as a guide in the event of a cell leaks.

Caution : If you see signs of moisture or liquid in the protective bag, DO NOT OPEN

the package

Protective Measures During

Cell Replacement:

Before opening the bag containing the sensor cell,

check the sensor cell for leakage. If the sensor cell

leaks, do not open the bag. If there is liquid around

the cell while in the instrument, wear eye and hand

protection.

Toxicological Information

Toxicity to Animals:

Mutagenicity:

Acute oral toxicity (LD50): 2730 mg/kg (Rat) (Calculated

value for the KOH solution.)

Lead tested positive as a mutagen in the Ames test.

Ecological Information

Ecotoxicity:

Environmental Fate:

The LC50 of lead for the daphnia magna is 3.6 mg/I, and

5.1 mg/l for the daphnia pulex.

Lead is bio-accumulative in most aquatic life and

mammals. It is highly mobile as lead dust or fume, yet

forms complexes with organic material which limits its

mobility.
