4-18 | Model 900 ADA / Model 930 Sulfur Pit Analyzers
F1 7 PrbTParaz Temperature zone parameters for the ASR900 Sample Probe, where ‘z’ = 1..6. The param-
eters and their default values are:
1 = Set Point (default = 130 °C)
2 = Proportional Band (default = 5 %)
3 = Integral time (default = 500 seconds)
4 = Derivative time (default = 0)
5 = Duty cycle default (default = 30 %)
6 = Duty cycle maximum (default = 100 %)
F1 8 — —
F1 9 Units Units of measurement used for displaying concentrations, temperatures, and pressures:
The value is the sum of ve bits:
Bit 0
Value Denition
1 0 = Metric Units
1 = Imperial Units
Bits 2,1
Value Denition
2,4* 0 = Normal concentration result (PPM).
2 = Normal concentration result (%).
4 = Finer (Low) concentration result (PPM).
6 = Coarse (High) concentration result (%).
*Sum of Bits 1 and 2 decimal value
Bit 3
Value Denition
8 0 = Display 4 items.
8 = Display 3 items.
Bit 4
Value Denition
16 0 = Remote Auto-CAL
16 = Remote Backpurge/Zero Flow
For example, if the analyzer is congured for Metric units, Coarse (High) concentration
result in percent (%), Display 3 items, Remote Auto-CAL, the result would be:
Bit 0 + Bits 2,1 + Bit 3 + Bit 4 [0 + 6 + 8 + 0 = 14].
The unit for input and output parameters (Metric or Imperial) is set at the factory, and
should not be changed (i.e., do not change from a Metric unit to an Imperial unit). If a
change is required, consult with AMETEK.
You can, however, change the concentration units freely back and forth between PPM and
mole percent (e.g., from Units = 0 to Units = 2, or from Units = 1 to Units = 3, or vice versa).
