Operating Instructions

WARNING: Do not store the F-950 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-950 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.

Fully charged main batteries allow for storage time of over 1 year. For long-term storage, consider attaching the potassium permanganate (KMnO4) external conditioning chamber to the inlet and outlet of the F-950 (see image below).

Aged batteries or batteries that started out with less charge will reduce the storage time available. The Li-ion batteries have little self-discharge and a life of about 3 years.
