Updated instructions and product information are available at: www.martindale-electric.co.uk 1.1 Meaning of Symbols and Markings Caution - refer to instructions Equipment complies with relevant EU Directives End of life disposal of this equipment should be in accordance with relevant EU Directives. 1.2 Precautions The CO190 must only be used by a skilled and competent person who is familiar with the relevant regulations, the safety risks involved and the consequent normal safe working practices, and under the conditions and for the purposes for which it has been constructed and specified. 1 2 Before use check the unit for cracks or any other damage. Make sure the unit is free from dust, grease and moisture. Also check any associated leads and accessories for damage. Do not use if damaged. The sensor in particular must be protected from exposure to water or dust as contamination can alter the performance characteristics of the unit. Always replace the CO190 in its storage case when not in use. Avoid severe mechanical shock or vibration and extreme temperature. To avoid corrosion from leaking batteries, remove the batteries when the unit is not in use for an extended period. 1.3 Effects on Health from CO Exposure The table below shows some effects on health due to prolonged exposure to various concentrations of CO. Level of CO ppm Effect on health 0-1 Normal background level 9 Maximum indoor air quality level 50 Maximum concentration for continuous exposure in any 8 hour average level 200 Mild headache, fatigue, nausea and dizziness 400 Frontal headache, life threatening after 3 hours 800 Death within 2 hours 1600 Nausea within 20 minutes, death within 1 hour 12800 Death within 1 to 3 minutes

unit and any accessories for damage. If there is any damage then consult your distributor immediately. 2.2 Description The CO190 has the following functions and features: � LCD display with backlight � Display hold � Auto power off � Alarm mode � Temperature measurement � Max value measurement � Hold mode 2.3 Accessories The CO190 comes with the following accessories: � Storage case � 4 x 1.5V AA LR6 batteries � Instructions 2.4 Battery Installation Refer to Section 4.1 (Battery Replacement). 4 3. OPERATION 3.1 Description of Press Buttons and CO190 Elements 1 Sensor 2 LCD display 3 HOLD The user can hold the measured value displayed on the screen 4 MAX Stores the highest measured value 5 Turns the CO190 On/Off 6 SET Set-up button for the CO alarm threshold 7 Turns the backlight on/off 8 °C / °F Changes the unit of measurement between C or F 9 Battery cover 5 3.2 Description of LCD symbols Battery capacity indicator Auto power off is active MAX Maximum recorded reading is displayed HOLD Hold mode is active 1888 CO level measured result Beeper Off indication Hi Alarm Level ppm Unit indication °C °F Temperature unit of measurement -188.8 Temperature measured result SET SET alarm ALARM Alarm Indication 3.3 Low Battery Indication If the symbol is displayed, the battery needs replacing as measurement accuracy can no longer be guaranteed (See section 4.1 Battery Replacement). 3.4 Power On/Off Press the button to switch on the meter. Hold the button for 3 seconds to switch off the CO190. The CO190 will perform a self-test calibration check when powered up. If the meter detects CO levels of 0-3ppm, the LCD will decrease from the initial value to zero. During the self- test, the display counts down from 60 to 0 and will beep when complete. If the CO190 passes the self-test, it will begin monitoring and shows a reading on the display. 3.5 Auto Power Off If the unit is inactive for a period of 30 minutes, the CO190 will automatically power off. To disable this function, press and hold the button while switching on the CO190. The HOLD symbol will disappear from the LCD to confirm the auto power off is disabled. 3.6 Backlight Press the button to turn on the display backlight. It will automatically turn off after 30 seconds if there is no further operation of the unit. 3.7 Unit of Measurement When the CO190 is switched on, it defaults to °C. Press the °C / °F button to switch between Celsius (°C) and Fahrenheit (°F). 6

Press the MAX button to enter the MAX mode. The CO190 will simultaneously store the maximum value to the memory and is updated with every new reading. Pressing the MAX button will display the MAX indicator and the maximum recorded value on the LCD. Press the MAX button again and the indicator flashes and the current measured value is displayed. To exit the MAX mode, press and hold the MAX button for two seconds. 3.9 Hold Mode To enter the HOLD mode, press the HOLD button while in measurement mode. The HOLD symbol will appear on the LCD. To exit display hold, press the HOLD button again. 3.10 SET Alarm Mode The default alarm threshold is set to 35ppm. The alarm can be set from 0 to 1000 ppm in this function. Press and hold the SET button to enter the CO high alarm threshold mode. The ALARM, SET and Hi symbols should be displayed on the screen with the current alarm threshold value flashing. While holding the SET button, press the °C / °F to increase the required alarm threshold or the MAX button to decrease the value. When the required value is displayed on the screen, release the SET button to save it. This value will be stored until further changes are made to the alarm mode. The alarm beeper gives audible indication, speeding up with CO concentration and becoming a continuous tone above 200 ppm (the recommended 15 minute exposure limit). Above 1000 ppm, the 7 alarm beeper sounds continuously with a high frequency tone. The LCD will display OL to indicate an over range reading. 3.11 Alarm Off Press and hold the button and then switch on the meter. The mute beeper icon will appear on the display. To re-enable the beeper, power off the CO190 and then switch it back on. 4. MAINTENANCE 4.1 Battery Replacement The battery compartment is on the rear of the unit. To gain access, undo the retaining screw and lift the cover away from the back of the unit. Replace with 4 new AA batteries (IEC LR6, NEDA 15A), observing correct polarity. Replace the battery cover. Note: Do not mix old and new batteries. 8 4.2 Calibration To maintain the integrity of measurements made using your instrument, Martindale Electric recommends that it is returned at least once a year to an approved Calibration Laboratory for recalibration and certification.
