2.7 Connecting to supply voltage
1 Make sure the on/off switch is in the OFF-position (
O
).
2 Connect the supplied mains cable between the instrument and a
grounded mains socket. Any voltage 100–240 V AC, 50–60 Hz
can be used.
The instrument contains no user replaceable fuse.
2.8 Preparing the instrument for use
Before the instrument is ready to use:
• Set the conductivity cell constant, see section B.2.3.
• Calibrate the temperature sensor, see section B.2.6.
• Calibrate the pH electrode (optional in ÄKTApurifier), see
section 3.6.
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 ÄKTAexplorer systems.
Note: When running chromatography using organic solvents, it is
recommended that the pH electrode is removed and the dummy
electrode inserted in its place, as organic solvents will cause pH
electrode degeneration.
Before performing these procedures you are recommended to read
sections 3.1–3.3.
