Two factors contribute to the time alignments delay. K5 uses a capillary sampling tube with a pump to draw a continuous gas sample into the
analyzers. The gas transport time depends on the dimensions of the tube and on the pump flow rate. Additionally the gas sensors have a response
time that must be added to the above delay for calculating the total delay.
The software of the K5 by carrying out the Gas Delay procedure calculates this delay and introduces a correction to realign both flow and gas
measurements.
This procedure must be carried out each time some changes occur in the sampling system, i.e. when the sampling tube is changed. However it is
recommended to carry out this calibration each week in order to prevent wrongs measurements.
1. Connect the turbine to the optoelectronic reader and this one to the K5 unit
2. Start breathing in the turbine at a constant rate. Synchronize the breath (inspiration and exhalation) with the acoustic signal.
3. After some cycles a message will appear confirming the delay calibration.
4. At the end of the calibration, exit with the EXIT icon
