Trigger Mode

A measurement in trigger mode begins with the valves closed and the pump off. To begin, press the square start button as prompted, to measure. Use the longer probe- the Trigger Mode Probe- (seen below) to take Trigger Mode measurements. This will turn on the pump and the ethylene sensor will stabilize before drawing in sample gas. Trigger mode will take longer to stabilize if the concentration is in a different range from the last sample (30 sec-1.5 min).

Once adequate sample has been collected, press the square button to stop the measurement and view the results. The maximum sample volume in this mode is 41 mL. The results will be saved to the SDcard.

Press the square start button to begin another measurement. Press the Left arrow to exit to the main menu.
