Diagnostics State (Basic/Advanced)
The Diagnostics State allows the built-in
sensor diagnostics to be disabled. When a
sensor does not have a solution ground such as
Non-Advantage (i.e., TB5) sensors, the
diagnostic signal cannot be injected into
process liquid. For these situations and
applications that use very pure water, the
sensor diagnostics should be disabled.
Set the DIAG (i.e., Diagnostics) State using
the following procedure:
1) Select the DIAG State using the SELECT
Key.
2) Toggle the diagnostics function to the
desired state (i.e., OFF or ON) using the
Key, and press the ENTER Key to enter
the new value.
Safe Mode One State (Basic/Advanced)
The Safe Mode One State determines the Analog
Output One level if an error condition occurs
that renders the analyzer inoperable. The
available states are FAIL.LO (i.e., fail low)
or FAIL.HI (i.e., fail high). For more
information on error conditions, see Section
13, Diagnostics.
Set the Safe Mode One State using the
following procedure:
1) Select the SAF.MD.1 State using the
SELECT Key.
2) Set the safe mode by using the NEXT Key
to toggle between FAIL.LO and FAIL.HI,
and use the ENTER Key to enter the new
value.
Safe Mode Two State (Basic/Advanced)
The Safe Mode Two State determines the Analog
Output Two level if an error condition occurs
that renders the analyzer inoperable. The
available states are FAIL.LO (i.e., fail low)
and FAIL.HI (i.e., fail high). For more
information on error conditions, see Section
