F6 0 IZeroz The measured current (mA) in the current output loop when the output is set to zero-scale
during the analyzer Zero, where ‘z’ = Output Channels 1..4. Refer to the Output Signal
Assignment code for the outputs assigned to these channels (press F2 6 from CFG mode).
The actual mA value is displayed next to the corresponding output channel when 4 mA
(Zero) is activated.
1 = IZero1
2 = IZero2
3 = IZero3
4 = IZero4
F6 1 ISpanz The measured full-scale current (mA) in the current output loop when output is set to
full-scale during the analyzer Span, where ‘z’ = Output Channels 1..4. Refer to the Output
Signal Assignment code for the outputs assigned to these channels (press F2 6 from CFG
mode). The actual mA value is displayed next to the corresponding output channel when
20 mA (Span) is activated.
1 = ISpan1
2 = ISpan2
3 = ISpan3
4 = ISpan4
F6 2 — —
F6 3 — —
F6 4 [Sv] The concentration (PPM) of sulfur vapour at analyzer conditions. This static value is used
for compensation purposes only.
F6 5 [COS] The concentration (PPM) of COS in the sample gas stream. If the concentration is not
known, enter ‘0’. This static value is used for compensation purposes only. (Applicable
only if measuring.)
F6 6 [CS2] The concentration (PPM) of CS
2
in the sample gas stream. If the concentration is not
known, enter ‘0’. This static value is used for compensation purposes only. (Applicable
only if measuring.)
F6 7 OpRatio The sample gas H
2
S to SO
2
ratio at which the plant is to be operated. For the conven-
tional operation of the modied-Claus Sulfur Recovery process, this value is 2.00. Do not
change the factory-default value without rst consulting with AMETEK.
F6 8 OpO󰀨set The analog output mid-scale (%) Air Demand signal. For the conventional operation of the
modied-Claus Sulfur Recovery process, this value is ‘0.’ Do not change the factory-
default value without rst consulting with AMETEK.
F6 9 ADFactor The Air Demand (F) factor as shown in the EEPROM Data Sheets (in the analyzer
Documentation Package shipped with the analyzer). This factor is application specic. Do
not change the factory-default value without rst consulting with AMETEK.
