6.5. Insert the flexible adapter hose (black) to the inlet dust filter of CO
2
Analyzer, then connect the plastic
valve into the TSL.
6.6. Take the CO
2
reading.
6.7. Increased carbon dioxide level indicates absence of any source of leaks from punctures, holes or
damages. CO
2
level of ambient air is 0.03% to 0.04%.

MAINTENANCE AND CARE
7.1. Do a regular (monthly) battery checkup and recharge it fully before use. Charge the instrument until
Red LED on charger turns to Green.
7.2. Do not keep the Analyzer without using for more than 3 months (from the date of shipment). Li-Ion
battery performance may be affected.
7.3. Perform the calibration check once in a month as this will ensure the accuracy of readings throughout
the life of the instrument.
7.4. Avoid using the analyzer in direct sunlight. Provide shade while using the CO
2
Analyzer in the field.
7.5. Do not expose the CO
2
Analyzer to excessive positive or negative pressure. It affects the accuracy of
the measurement.
7.6. Occasionally, the casing of the CO
2
Analyzer may be cleaned with a slightly damp lint free cloth. Wipe
the CO
2
Analyzer thoroughly but care should be taken not to allow any water or moisture to enter.
