SPIRO ANALYZER GAS BENCH USERS MANUAL 2. Installation 2.1 Using RS232 Users can get the sensor measurement result from serial port, the communication protocol command according to Annex. Workflow is as follows: 1. Warm-up: need warm-up for some time.the signal is unstable during this period. 2. Zeroing: inlet zero gasO2/N2 more than 10s after the sensor stability, Send zero command "11 01 03 EB" and complete zeroing, adjust the sensor measurements result to 0. 3. Take measurements result: send "11 01 01 ED" order, read the measurement results. Send “11 01 03 EB” order complete zeroing send “...

SPIRO ANALYZER GAS BENCH USERS MANUAL Warm up half an hour After signal stability, send zero adjustment order “4B”,complete zeroing. RS232 zero adjustment Warm up half an hour After signal stability, send zero adjustment order “4C”,complete zeroing. RS232 span adjustment 3. Operation and Maintenance 3.1 Operation After finishing circuit and pneumatic routine of gas sensor module, power it on, then the module start to work. We suggest you can do the test after 10 to 15 minutes for warming-up. Open the pump of gas sensor module for sampling in order to absorbing the sample gas, screw the flow meter...
