Measure Menu: Taking a Measurement

To begin taking measurements, select the Measure Menu by pressing the right arrow when Measure is highlighted on the Main Menu display. Make sure the IN and OUT ports on the front panel of the instrument are clear from any obstructions. Create and open a file before starting a measurement, otherwise the default filename on the SD card is File01.

If sampling ambient air, turn the unit on and leave the front ports free of obstruction. If sampling a container or pallet, connect the Viton tubing to the IN port and place the end of the tubing into the container or pallet to be sampled. If using the F-900RK, place the fruit to be sampled in the fruit chamber, and connect it to the IN port on the unit. It is up to the specific setup whether the OUT tubing is connected to the OUT port with Chamber Out filled with potassium permanganate (KMnO₄) and set to on. If left disconnected from the OUT port, the fruit chamber is allowed to replenish with ambient air.
