CO Key Model 8551 Only Press the CO key to display CO readings Carbon monoxide concentration readings are displayed in units of parts per million ppm The CO sensor is located at the tip of the probe SAMPLE Key Press the SAMPLE key to start stop data sampling The word SAMPLE appears in the upper right corner of the display while the Q TRAK is taking a sample When sampling is stopped the Q TRAK automatically scrolls through statistics for the sample that just ended TIME CONSTANT Key Momentarily press and release the TIME CONSTANT key to view the current time constant To change the time constant press and hold the key down The available time constant choices will sequence on the display When the desired value is displayed immediately release the key The time constant is actually an averaging period The Q TRAK display is always updated every second however the reading displayed is the average reading over the last time constant period For example if the current time constant is set to 10 seconds the display shows readings averaged over the previous 10 seconds updated every second This is also called a 10 second moving average As configured at the factory the available time constant values are 2 5 10 15 and 20 seconds The internal list of time constant values can be altered using Q TRAK Data Analysis Software supplied with the Q TRAK The range of time constants allowed is 2 60 seconds See
5. If the programmed start time and date has already passed pressing the SAMPLE key has no effect The program never executes Operation 19 Setting the start time but no start date causes the Q TRAK to start at the specified time regardless of the date If no start time is set the Q TRAK waits for you to press the SAMPLE key and starts sampling immediately If no test length is set the Q TRAK samples continuously until the SAMPLE key is pressed to stop sampling or until the memory is full When a pre programmed test ends the Q TRAK automatically shuts off When it is turned on again it will be in Survey mode Memory Considerations The Q TRAK has a great deal of memory and you will not normally have to be concerned with running out The Q TRAK has 128 000 bytes of internal memory This should be considered when selecting a logging interval Shorter logging intervals use memory more quickly than longer intervals A recorded data set consumes 6 bytes for Model 8550 and 8 bytes for Model 8551 2 each for CO temperature and humidity In addition each test labeled with a TEST ID number needs 100 bytes for storing statistics and setup information The formulas below ignore this 100 bytes to keep the calculations simpler Based on this information the Q TRAK is capable of storing approximately 21 000 data sets for Model 8550 and 15 750 for Model 8551 Note LOG 2 and LOG 3 modes can be programmed to record any of the me
6. Replacing the CO Sensor The electro chemical CO sensor will need to be replaced approximately once a year Conditions that may indicate a sensor needs to be replaced are 1 the sensor will not hold calibration or 2 the response is very unstable Caution must be taken when operating at very low or high temperatures Exposing the sensor to sub freezing temperatures can cause permanent damage to the sensor Exposing the sensor to high temperature for long periods of time can cause the sensor to dry out which will shorten the sensor life The sensor has a built in filter to eliminate interfering gasses This filter will last the life of the sensor under normal background gas levels To replace the sensor follow the procedure below WARNING The CO sensor contains a corrosive material avoid contact with eyes and skin 1 Unscrew cap from end of probe 2 Carefully bend flex circuit assembly away from old CO sensor 3 Remove old sensor by gently pulling sensor straight off the end of the probe Do not twist the sensor this will damage the connector 4 Obtain a new sensor tear open foil pouch and remove new sensor Inspect new sensor for visible signs of damage or leakage Discard old sensor 26 Chapter 4 5 Line up notch on sensor with connector and gently push sensor onto the connector 6 While holding flex circuit against CO sensor carefully thread thermistor through cap and screw cap on probe 7 Turn on Q TRAK A
