Output Signal Assignment/code rules:
• To assign a calculated result to the analog output and the User
Interface with the track-and-hold function disabled during Auto-Zero,
enter a single-digit code (1, 2, etc.).
• To assign a calculated result to the analog output only – it will not be
displayed – with the track-and-hold function disabled during Auto-
Zero, add 100 to the single-digit code (101, 102, etc.).
• To assign a calculated result to the analog output and the User
Interface with the track-and-hold function enabled during Auto-Zero,
add 10 to the single-digit code (11, 12, etc.).
• To assign a calculated result to the analog output only – it will not be
displayed – with the track-and-hold function enabled during Auto-
Zero, add 110 to the single-digit code (111, 112, etc.).
• Displayed results are active during an Auto-Zero.
Assigning Output Signals With the Track-and-Hold Function Enabled/
Disabled
When enabled, the Track-and-Hold function maintains the output at the
value calculated just before an Auto-Zero begins. When disabled, the outputs
are forced to use the operator-entered fixed values. The outputs will hold at
these values for the duration of the Auto-Zero and the Sample Delay Time
(SDelay).
Hold function enabled examples (output uses value calculated just before an
Auto-Zero begins):
Example 1:
To assign the Air Demand signal to Output 1 and the User Interface and
return to CFG mode normal display, press:
F2 6 1 Del 17 Ent Ent
Example 2:
To assign the SO
2
concentration to Output 2 only and return to CFG mode
normal display, press:
F2 6 2 Del 111 Ent Ent
