2 INSTRUCTIONS SGA71 WARNING This instrument should only be used by trained and competent persons, after due consideration of any risks involved. Carbon Monoxide is life threatening even at relatively low concentrations be sure you understand the risks before investigating potential leaks.

3 INSTRUCTIONS FOR USE ON/OFF The SGA71 is operated by a single button for ON and for OFF. When the unit is switched on (only switch on where you are sure the air is fresh) it automatically self zeros in 50 seconds. During countdown the display shows time remaining as two digits. Turn ON Countdown 39 When the countdown reaches 00 the meter will set its sensor to zero and display CO concentration as three digits Normal display CO ppm 000 Hold down the ON/OFF key for 2 seconds and release to switch the meter OFF, the display will show a single digit and count down for 9 seconds. Turn OFF Countdown 9 If turned off accidentally, press the button again and hold for 2 seconds and release to cancel.

4 MAX button Maximum value Display MAX 039 Press MAX to display the highest reading detected while the meter is switched ON. HOLD button Holds value when button pressed 025 HOLD Freezes the display with the CO reading at the time the HOLD button. VISUAL INDICATOR This is the LED located at the top of the meter. At different CO concentrations the LED changes colour to give visual warning: OFF: GREEN: YELLOW: RED: 0-1 ppm 2-9 ppm ppm 35 ppm or higher

5 AUDIBLE ALARM The instrument is pre-set with an alarm at 35 ppm, if this level is exceeded an audible tick will sound. The tick rate will increase with higher concentrations, check the LCD display for actual level. While the alarm is sounding the unit can not be turned off until the level has dropped below 35 ppm. BACK-LIGHT To activate the back-light press the ON/OFF key quickly once. Do not hold down the key or the unit will switch off. To turn off the back-light press quickly again. Note using the back-light decreases battery life. BATTERY INDICATION Low battery indication BAT 039 If the battery falls below a pre-set level the symbol BAT appears in the display. Do not use the instrument when this symbol is present. Replace the battery immediately.

6 TROUBLESHOOTING If the display fails to stabilise at around zero within a few minutes this may indicate a defective sensor or a sensor that has been exposed to excessive levels of CO. If the symptom persists seek advice from Kane International Ltd. Always check for correct operation before use. Use a known source of CO (e.g. a lighted cigarette or a gas flame) taking care to act in a safe manner and not to expose the SGA71 sensor at too high a temperature. If the unit does not change as expected, return to Kane International Ltd for investigation. If during use you detect CO leaks be sure you know the appropriate actions to take to protect yourself and others. Before switching off the instrument always expose it to fresh air until the reading falls below 5 ppm. Note that the reading falls much more slowly than it rises so you may need to wait two or three minutes.
