Influence variables
Sample gas pressure
Deviation at zero point ≤ 0.2 % of smallest measuring range / 1% pressure
change or ≤ 50 vpm O
2
/ 1% pressure change,
whichever is larger
Deviation from the span
gas
Deviation ≤ 0.2% of current span / 1% pressure
change or 50 vpm O
2
/ 1% pressure change, which‐
ever is larger
Sample gas flow
Deviation at zero point ≤ 1 % of smallest measuring range per 0.1 l / min
flow rate change or 50 vpm O
2
per 0.1 l / min flow
rate change within the permissible flow rate range
(The larger value is always in effect)
Deviation from the span
gas
≤ 1 % of smallest measured value per 0.1 l / min
flow rate change or 50 vpm O
2
per 0.1 l / min flow
rate change within the permissible flow rate range
(The larger value is always in effect)
Accompanying gases Zero point deviation (cross-sensitivity) in accord‐
ance with Table A.1 of EN 61207-3
Power supply (mains voltage variations in range
