A predicted concentration is reported by the summation
Unpacking the F-750
The F-750 will arrive with removable, rechargeable batteries, two battery chargers (one for the wall and
a car charger), a white Teflon calibration disc, and a clip to attach the F-750 to a belt. There is a tripod
mount located on the bottom of the F-750 Produce Quality Meter case.
Operating Instructions
The F-70 uses 18650 Li-ion 3.7V 3100mAh rechargeable batteries. The batteries must be removed from
the F-750 to be charged. To remove the batteries, twist the battery compartment cap, located on the
bottom of the case. The cap can be twisted with fingers or a screw-driver to tighten or loosen. Take
care when removing batteries, as the cap is spring loaded. Both batteries should be inserted into the
unit positive (+) side first (towards lens side).
