1. Read the calibration gas cylinder pressure on the pressure gauge.
2.
If there is still a minimum pressure of over 1.0 MPa, the cylinder can remain in
use. Note: if the pressure is close to the minimum, the cylinder must be replaced
independently of the maintenance work if necessary.
3. Read the carrier gas cylinder pressure on the pressure gauge.
4.
If there is still a minimum pressure of over 1.0 MPa, the cylinder can remain in
use. Note: if the pressure is close to the minimum, the cylinder must be replaced
independently of the maintenance work if necessary.
5.
Please notify your TAC if you require a new gas cylinder. You may use the
device without calibration gas but not without carrier gas. In this case, the
results are less accurate.

Reading the gauges
1.
Read the process gas inlet pressure of the sample gas streams (1 – 5) on the
pressure gauges.
2.
If the inlet pressure (PG) is not like specified (see chapter “Technical
Specifications), adjust the pressure within this range
3.
If you cannot complete step 2, disconnect the gas and voltage supply. Do not
proceed with any further action or work unless step 2 is correct.
4.
Attempt the repair work described in sections 5 and 6 of this manual. If
necessary, notify your TAC.
