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.
Note: The analyzer setup does not configure relays, outputs, network cards,
calculations or calibration parameters. Refer to
on page 16 for
configuration information for calibration parameters. Refer to
on page 11 for configuration information for relays, outputs or network cards.
Refer to
on page 10 to setup calculations.
Configure the sequencer (optional)
Option only available for the multi-channel version of the analyzer.

Description
ACTIVATE
CHANNELS
Starts or stops measurements for individual sample
sources. Use the UP and DOWN navigation keys to scroll
through the channels. Deselect a channel with the LEFT
navigation key. Push enter to confirm.
Note: Inactive channels are shown with a "~" character
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
on page 16 to start a calibration.
Operation
W A R N I N G
Potential fire and explosion hazard. This equipment is intended for only aqueous
type samples. Use with flammable samples can result in a fire or explosion.
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.
Set up the reagents and standards
Make sure to set the sample flow rate and install the reagent bottles
before this task is started.
1. Push menu and then go to REAGENTS/STANDARDS.
2. Select one of the options. Use the SET options when the volume of
existing reagents/standards needs to be adjusted. Use the RESET
options when reagents/standards are replaced or renewed (bottles
are replaced).
Option
Description
SET REAGENT
LEVEL
Sets the volume of a specific reagent in the reagent
bottle to an estimated value. Range: 1–100%.
SET STANDARD
LEVEL
Sets the volume of a specific standard solution in the
standard bottle to an estimated value. Range: 1–
100%.
