Unpacking & Getting Ready for Use
If you have just received your F-751, the instrument will arrive
in a carrying case that includes:
•
The F-751 Produce Quality Meter
•
SD card
•
2 sets of removeable rechargeable standard-sized
batteries (4). Additional button-top 19670, or protected
18650, batteries can be purchased from a preferred
battery vendor.
•
Battery charger (3)
•
Hand strap
Loading the Battery
The F-751 uses 18650 Li-ion 3.7V 3100mAh rechargeable
batteries. The batteries must be removed from the F-751 to be
charged. To remove the batteries, twist the battery
compartment cap, located on the bottom of the device under
the rubber bumper. The cap can be twisted with fingers or a
screwdriver to tighten or loosen. Use caution when removing
batteries, as the cap is spring loaded. Both batteries should be
inserted into the unit positive (+) side first (towards lens side).
Warning
: Do not drop batteries, this may cause them to crack
and rupture.
