■ Zero set process by White Teflon built in the head-cover
1. To measure the internal quality of the fruit, the reference material (White Teflon) must be scanned
first (zero set process).
2. When the power turns on, the instrument automatically scans the reference material (White Teflon)
during its initialization procedure.
3. User may have to scan the reference material manually, when there is a change in the
measurement model or when outside measurement conditions (temperature, etc) are altered
drastically.
4. To scan the reference material, close the head-cover to the instrument, and press button
for rebooting (power off and on).
5. Make sure that the head-cover (White Teflon) does not move out from the instrument until the
initialization completed.
■ How to place the fruit with the instrument
1. Before taking a measurement, clean the object fruit thoroughly if its surface is excessively dirty
or dusty.
2. As shown in the picture below, grab the fruit and smoothly push it to the instrument, so that the
center part of the fruit adheres closely to inside rubber shield.
3. Press the trigger and keep applying a steady force to the fruit for about 2 seconds (until the
“beep - beep“ sound ends). Make sure that the fruit doesn't move during scanning.
4. The instrument structure has been designed to fit into a standard size of object fruit.
5. Hence measuring a fruit smaller than standard size, there may be a possibility that superfluous
light may leak into the optical sensor. In that case, try to move the measuring position and to
avoid such leakage during the measurement or user may have to wear a black glove to cover up a
possible light-leak.
