6.1 Installation location requirements
6.2 Metrological specifications
Geographic height at installation location: ≤ 2500 m altitude
[1]
[1] Higher altitudes can be realized (option); compensation for height influence.
Ambient air pressure: 700 … 1200 hPa
Jolts: < 2.7 g
Fitting position influence (tilted position influ-
ence)
No influence for constant tilted position up to ±15°
[2]
[2] Perform an adjustment after changing the fitting position.
Measured variable: O

volume concentration
Possible measuring ranges:

[1] Actual measuring range, see specification of individual device.
– Standard: 0 … 25% by vol. O

– Smallest measuring range: 0 … 10% by vol. O

Detection limit (3σ):
[2]
[2] With constant electronic damping with time constant T
90, el.
= 15 s.
< 0.3% of measurement span
Linearity deviation: < 1% of measurement span
Zero point drift ≤2% of the smallest measuring range per
month
Reference point drift: ≤ 2% of measured value per week
Ambient temperature influence:
– Zero point: < 1% of measurement span per 10 K
– Reference point: < 1% of measurement span per 10 K
Air pressure influence
[3]
[3] When the sample gas outlet is open: Atmospheric pressure influence.
When the sample gas outlet is fed back to the process: Process gas pressure influence.
– Without pressure compensation: < 1% of measured value per 1% pressure change
– With automatic pressure compensation:
[4] [5]
[4] When the sample gas outlet is open: Option “Baro correction”.
When the sample gas outlet is fed back to the process: Option “Sample gas pressure correction”.
[5] Effective range: 700 … 1300 hPa.
≤ 0.1% of measured value per 1% pressure change
Sample gas volume flow influence (throughflow
dependency)
[6]
[6] In range 10 … 60 l/h.
< 1% of measured value
Mains voltage/mains frequency influence:
[7]
[7] Within the specified voltage and frequency ranges.
< 0.5% of smallest measurement span
Display delay (T
90 total
): Typical 20 s
[8]
[8] For sample gas volume flow = 60 l/h.
Run-in time: None
