3.5.6.1 Diagnostics
The Diagnostics menu provides a large variety of features that allow the user
to investigate problems with the analyzer or gain a greater insight into what
the instrument is doing. This Menu contains 3 sub menus and 3 editable fields,
the 3 editable fields are presented directly below for your convenience and the
sub menus after them.
3.5.6.1.1 Pres/temp/flow Comp
Set to either On or Off.
On is used to compensate analyzer measurements for environmental
fluctuations that might affect readings (pressure, temperature and flow).
Off is used only when running diagnostics to see fluctuations in
readings.
3.5.6.1.2 Diagnostics mode
The instrument can be placed in 4 diagnostic modes:
• Operate which leaves the instrument in normal operation mode
• Optic which configures the instrument for tests on the optical
measurement source
• Electrical which configures the instrument for testing of the
electrical circuits
• Preamp which configures the instrument for testing of the pre-
amplification circuitry
3.5.6.1.3 Control loop
When “enabled” the instrument will control all processes within the
instrument.
• Selecting Disabled will pause the instruments control over certain
processes and parameters (digital pots, internal pump etc). The
user can now manually alter and adjust digital pots.
• When instrument is put back in “Enabled” mode or taken back to
main screen the new pots will be set and instrument will resume
control over pots.
