8. If the cuvette pressure value changes more, troubleshoot tubing and fittings. If the
problem persists, return the analyzer to PHASEIN.
Note:
In step 5, if the cuvette pressure is less than 15 kPa below atmospheric
pressure, repeat steps 1 to 3 blocking the exhaust port quicker.
Gas span check
Confirm the gas measurements values by performing the following sequence
1. Connect a new Nomoline sampling line to the ISA gas analyzer.
2. Warm up for at least 1 min.
3. Connect the calibration gas to the ISA gas analyzer. The calibration gas shall have
an accuracy of at least ±
0.03 vol% or ±
(0.02 vol% +0.1% of reading), whichever
is greater.
4. Supply the calibration gas.
5. Check that the displayed gas concentration readings correspond to the calibration
gas values.
6. The gas readings shall be within the following ranges:
a. CO
2
± (
0.3 vol% + 4% of reading)
b. N
2
O
± (
2 vol% + 5% of reading)
c. Agents ±
(0.2 vol% + 10% of reading)
d. O
2
± (
2 vol% + 2% of reading)
7. If the gas readings are outside the specified range, perform a gas span calibration for
the failing gases. If failing on Agents, the span calibration shall always be performed
using DES.
Gas span calibration
Only
perform the gas span calibration if the gas span check fails repeatedly.
Before performing the gas span calibration, ensure that the SET O2 and SET N2O
