Set the Safe Mode Two State using the
following procedure:
1) Select the SAF.MD.2 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.
Spike State (Advanced)
The Spike State sets the diagnostic spike
level as a percent of output. This level will
determine the magnitude of the spike.
When the Spike has been set for any level
greater than 0% and is enabled in the Spike
Output State, the TB84PH Advantage Series
analyzer will modulate the Analog Output One
signal by the configured level for one second
out of every six seconds when a problem
condition is detected. Using this modulation,
the analyzer informs the operator of a
detected diagnostic condition. For more
information on problem conditions, see Section
13, Diagnostics. For a description of the
diagnostic spike feature, see Section 2,
Analyzer Functionality And Operator Interface
Controls.
Set the Spike State using the following
procedure:
1) Select the SPIKE State using the SELECT
Key.
2) Set the SPK.MAG (i.e., spike magnitude)
using the Key to increment the
blinking digit and the Key to move to
the next digit, and press the ENTER Key
to enter the new value. The Spike
Magnitude is entered as a percentage of
the 16 milliampere output range for a
four to 20 milliampere output or 20
milliampere output range for a zero to 20
milliampere output (e.g., 10% will
generate a 1.6 milliampere spike for a
four to 20 milliampere output range).
Note: Once the Spike State is OFF, changing the
configured spike level in the Configure Mode
will not reenable the Spike State. The Spike
State can only be turned ON or OFF in the
