Hot Keys
in Monitor Mode can be used to turn Chamber In an Chamber Out on or off at any point
during the measurement period
Chamber In On/Off:
LEFT and DOWN arrows simultaneously. Includes or does not include
Chamber In (B) as a part of the measurement sample stream.
Chamber Out On/Off:
RIGHT and DOWN arrows simultaneously. Includes or does not include
Chamber Out (A) from flow path.
To avoid drawing water into the internal tubing of the F-900 when using SPECIAL mode:
1.
Fill Conditioning Chamber In (B) only to the fill line and never completely fill the
conditioning chamber with water.
2.
Always keep the top panel of the F-900 facing up and do not tilt the instrument when there
is water in the conditioning chamber. When operating in SPECIAL mode, do not operate the
instrument with the display panel facing upwards.
3.
Do not transport or tip the F-900 if moisture is in Chamber In. Before transport or moving
the F-900, Chamber In should be completely dry to prevent even small drops of liquid from
entering the unit.
4.
If the Relative Humidity sensor reads high, open the top panel of the unit and inspect hoses
for liquid. If liquid has accumulated at the hydrophobic (blue) filter, it should be
disconnected and drained. If liquid has penetrated the hydrophobic filter the unit will need
to be serviced to prevent circuit board failure. For instruction to open the top panel, see
Refilling the Electrochemical Sensor section of this manual. Contact
with any questions.
