≤ 1 % of span
≤ 0.5 % of span
≤ 2 % of span per week;
for ranges smaller than Class 1 to Class 2: ≤ 1.5 % of span per day
(Recommendation: daily automatic zero-point calibration)
≤ 1 % of measured value per week
• Limas11 IR: ≤ 0.5 % of span at electronic T90 time (static / dynamic) = 60 / 5 sec.
for ranges smaller than Class 1 to Class 2: ≤ 1 % of span
≤ 1 % of span;
for ranges smaller than Class 1 to Class 2: ≤ 2 % of span
Flow in 20 to 100 l/h range: within detection limit
The knowledge of the sample gas composition is necessary for the analyzer
configuration. Selectivity measures to reduce associated gas effect (optional):
Installation of filter cells or internal electronic cross-sensitivity correction or carrier
gas correction for a sample component by other sample components measured
with the Limas11.
• At zero-point: ≤ 1 % of span per 10 °C,
for ranges smaller than Class 1 to Class 2: ≤ 2 % of span per 10 °C
• On sensitivity: ≤ 1 % of measured value per 10 °C
Ambient temperature in permissible range, sample cell thermostat temperature
= 60 °C
• On sensitivity with pressure correction via integral pressure sensor: ≤ 0.2 % of
measured value per 1 % air pressure change
The pressure sensor is located in the sample gas path if hoses are used as the
internal gas lines. An external port is used for the pressure sensor if tubing is used
for the internal gas lines.
Pressure sensor working range: p
24 VDC ± 5 %: ≤ 0.2 % of span

without signal damping (low pass filter). Low-pass time constant adjustable from
0 to 60 sec.
