Fidas24: Notes for calibrating
Sample components and measurement ranges
The Fidas24 analyzer module has always at least 1 sample component with
1 measurement range.
Up to 4 sample components with up to 4 measurement ranges are possible
for each measuring component.
NOTE
A substitute gas component can be set up at the factory even if it has not
been ordered.
Setting of measurement ranges
The measurement ranges are factory-set per customer order.
The measurement range can be varied as follows depending on the adjusted
amplification:
Low amplification: 150,000 ppm C1 to 100 ppm C1
High amplification: 3,000 ppm C1 to 10 ppm C1
The smallest measurement range is 0 to 5 mg org. C/m 3 equivalent
to 0 to 10 ppm CH
4
.
NOTE
The associated amplification levels are set at the factory during calibration.
They can only be changed using the TCT test and calibration software.
Setting the calibration method
For detailed information on the calibration methods, see the "Calibration
methods" (see page 223) section.
