Note: The analyzer stays in initialization mode until the configuration is
complete.
5. Select the channel.
6. Select the measurement mode.
7. The setup results for the channel, sample flow, sample pressure and
minimum flow are shown. Make sure that the following values are
within range:
• Sample pressure: minimum 0.14 bar (2 psi)
Note: The maximum pressure is regulated by a pressure regulator at
0.28 bar (4 psi).
• Minimum flow: 55 mL/minute
8. Push enter to confirm.
9. When prompted, make sure that the reagent bottles are full and
confirm with YES.
10. When prompted, make sure that the standard bottles are full and
confirm with YES.
11. Reagent 1 has a known effect on the measurement value. The value
attributed to this effect is printed on the bottle as a BLANK value.
When prompted, enter this value.
Note: The analyzer setup does not configure relays, outputs, network cards,
calculations or calibration parameters. Refer to
Calibration on page 17 for

before the channel name on all displays.
SEQUENCE
CHANNELS Sets the measurement order of the sample sources. Use
the UP and DOWN navigation keys to scroll through the
sequence. For each sequence number use the LEFT and
RIGHT navigation keys to select a channel. Push enter to
confirm.
Calibrate the analyzer
The manufacturer recommends calibration of the analyzer after 1 day of
operation to allow all system components to stabilize. Refer to

C A U T I O N
Chemical hazard. Always follow appropriate laboratory safety
procedures when chemicals are handled. Always wear all personal
protective equipment appropriate to the chemicals used.
When the lower door is opened, the current measurement or calibration
is stopped. When the lower door is closed, the previous measurement or
calibration starts again.
