If the instrument locks-up or requires a hard shut-off for any other reason, hold down power button for 
10 seconds.  This will force the F-760 power to turn off.  Then, the instrument can be restarted. 

To take a measurement, power on the F-750 Produce Quality Meter.  The current model will be 
displayed. To change the model refer to the “Select Model” section on Page 3 of the manual. Hold the 
sample to the lens so that it makes contact with the perimeter of the bracket around the lens. Press the 
square/start button to record a new measurement.   

During the measurement the instrument will switch to the scan display and collect and process the data.  
As the measurement is being collected, large blocks will appear at the bottom of the display screen.  
Keep the sample in place as all blocks progress. The measurement is taking place during the 1

st

 and 2

nd

 

block going across screen.  The 3

rd

 block is for processing data, the 4

th

block is for saving measurements.  

At the 5

th

block, the measurement is complete and displays the record to be reviewed.  Once at the 3

rd

 

block or “processing” the sample can be removed from instrument. 

The data is stored to a removable SD card. To remove, press into the unit and the card will eject. To 
replace, insert metal side first with the label facing the back of the unit. 

A Glossary of Vocabulary Definitions is located at the end of this manual.  

Navigating Menus 

Use the power button to turn on the F-750.  After the instrument powers on, the display will show the 
current model loaded on the unit and the battery life.  Instructions at the bottom of the display indicate 
to press the square/start button to record a new measurement or press the right arrow to view the 
main menu.   

 

 

 

 

 

Use the right arrow to get to the Main Menu.  Once at the Main Menu, the left arrow can be used to go 
back or exit to the previous screen.  The Main Menu consists of three options, select model, browse 
records, or setup instrument.
