Automatic Background Logic, or ABC Logic, is a

patented self-calibration technique that is designed to

be used in applications where concentrations will drop

to outside ambient conditions (400 ppm) at least three

times in a 14 day period, typically during unoccupied

periods.

*Full accuracy to be achieved utilizing ABC Logic. With

ABC Logic enabled, the sensor will typically reach its

operational accuracy after 25 hours of continuous

operation at a condition that it was exposed to ambient

will maintain accuracy specifications with ABC Logic

enabled, given that it is at least four times in 21 days

exposed to the reference value and this reference

value is the lowest concentration to which the sensor

is exposed. ABC Logic requires continuous operation of

the sensor for periods of at least 24 hours. Note: Applies

when used in typical residential ambient air. Consult

Telaire if other gases or corrosive agents are part of the

application environment.

Module 6613-F (Flow Through)

The diffusion membrane is replaced with a non-

permeable seal. The two flow ports can be used

for flow through sampling. Flow rate of 50 cc/min

recommended.

Handling and Installation

on a printed circuit board and should be treated

carefully. Precautions should be taken to observe

specified limits and prevent damage from electrostatic

discharge or rough handling. Please refer to ANSI/ESD

S20. 20-1999 for more information on preventing ESD

damage and IPC 610 Rev D for more information on

proper electronic assembly practices.

Calibration

Telaire does not recommend the customer recalibrate

the T6613 module after installation. The sensor ABC

Logic algorithm will begin after 24 hours, adjusting the

sensor measurement resulting in sensor-to-sensor

consistency. If immediate consistency is desired, the

sensors may be single point calibrated using pre-mixed

reference gas or ambient air measured by a reference

sensor.
