User manual

Connect two UniNet 1 cables to the UniNet 1 connectors. The

module can be connected in series anywhere between the PC and a

termination plug. The UniNet 1 link connects, in series, the PC with

Pump P-920, Monitor UPC-900 and the Frac-900. The termination

plug is connected to the last module in the chain.

2.8 Connecting to supply voltage

1 Make sure the on/off switch is in the OFF-position (0).

2 Connect the supplied mains cable between the module and a

grounded mains socket. Any voltage from 100–240 V AC,

50–60 Hz can be used.

Note: The module contains no user-replaceable fuse.

2.9 Preparing the module for use

Before performing the following procedures, we recommend you

read sections 3.1–3.3.

• Calibrate the pH electrode, see section 3.6.

• Set the conductivity cell constant, see section B.2.3.

(Only required when the flow cell has been replaced.)

• Calibrate the temperature sensor, see section B.2.6.

(Only required if the monitor is to be used for high accuracy

measurements, or if the flow cell has been replaced.)

Note: The conductivity cell constant is shown on the packaging.

Retain the packaging in case the conductivity cell constant needs to

be re-entered.

Note: The measured temperature is the temperature in the

conductivity flow cell, which can differ from the ambient

temperature in ÄKTAdesign systems.

Note: When running chromatography using organic solvents, we

recommend that the pH electrode is removed and the dummy

electrode inserted in its place as organic solvents will cause pH

electrode degeneration.

WARNING! The module must be connected to a grounded

mains socket.
