Operating Instructions
WARNING:
Do not store the F-960 without batteries! Charged
batteries must be present in the instrument to maintain the
accuracy of the sensors, even when the unit is powered off.
If the batteries of the F-960 discharge during storage, replace
with charged batteries and allow the instrument to stabilize 48
hours before use. There is a small internal battery to maintain
the bias voltage for the ethylene electrochemical sensor. This
small internal battery will last for 1 day without the main
batteries before sensor sensitivity is affected by losing its bias
voltage. The calibration parameter data is intact with or without
batteries.
Loading the Battery
WARNING: Spring-loaded battery cartridge
The F-960 uses 18650 Li-ion 3.7V
3100mAh rechargeable batteries. For
longer lifespan, charge the batteries at
0.25A. For a faster charge, charge at
1A. The batteries must be removed
from the F-960 to be charged. If the
batteries of the F-960 discharge during
storage, replace with charged batteries.
The Li-ion batteries have little self-
discharge and a lifetime of ~ 3 years.
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
