
Cycles
This screen is used to program the period and the timing of the automatic cycles.
The timings
programmed here are also those of the manually launched cycles.
The possible automatic cycles are as follows:

Zero: zero air check

Span: span gas check

Z. Ref: automatic zero adjust correction

Auto: automatic calibration coefficient correction
The
Remote
fields are used to configure the cycle remote controls (ESTEL board option), Zero, Zero
reference, Auto, or Span. The status programmed in the
Cyclical
fields (ON = active, OFF = inactive)
controls the analyzer’s reaction when a dry contact is closed on the remote controls input (see Table
3-1 in Chapter 3).
The
Inlet
fields are used to select the gas inlets used during automatic sequences. The reference
concentrations for auto-calibration are those programmed in the previous menu. During a manually
launched cycle, the selected inlet is the current one.
The
Starting time
field is used to program the hour when the cycles are launched. If a 24 h Zero cycle,
a 24 h Auto cycle, and a 24 h Span cycle are programmed, the sequence is launched at starting time
according to the following priority: Z. Ref., Zero, Auto, and then Span.
To turn the function modes OFF or ON, use the [  ] or [  ] keys to select OFF or ON to be modified,
press the [

] key to activate the selected parameter and enable the modification, and then use [  ] or
[  ] to make the modification. Finally, press the [ ] key to validate the modification.
