Operating Manual
Message and Code Description and Remedial Action
Code 7049 Wavelength calibration failed
– check and flush flow cell. Check the flow cell (see Checking the Flow Cell ( } page 145) ). If
the message still appears, proceed as follows:
Check the lamps: If a lamp was newly installed, ensure that it is
installed properly. If a lamp is old (counting, for example, more
than 2000 operating hours), replace the lamp (see
Lamps
( } page 107) ).
Code 7051 Bad flow cell position. The flow cell is not correctly positioned inside the flow cell
opening.
Check the flow cell installation (see Checking the Flow Cell
( } page 145) ).
Check the flow cell contact pins for proper alignment inside the
flow cell opening.
Code 7056 Holmium validation failed –
wavelength outside limits. Repeat the validation (see Performing a Wavelength Validation
and Calibration ( } page 119) ). If the message still appears,
proceed as follows:
Perform a calibration and repeat the validation again.
Remove and install the flow cell. Flush the flow cell with pure
HPLC-grade water with a flow rate of > 1 mL/min for several
minutes (Nano flow cells: Flush with pure HPLC-grade water with
the maximum possible flow rate for the respective range for
several minutes).
Install a different flow cell or a diagnostic cell (see Installing a Flow
Cell (
}
page 59) or Installing a Diagnostic Cell (
}
page 118) ).
Perform a validation. Perform a calibration and repeat the
validation again. If the message disappears with a different cell,
the flow cell that was previously installed may be clogged.
If the error message persists, contact Technical Support.
Code 7057 Holmium validation failed –
specified wavelength not found. Repeat the validation. If the message still appears, proceed as
follows:
Perform a calibration and repeat the validation again.
Remove and install the flow cell. Flush the flow cell with pure
HPLC-grade water with a flow rate of > 1 mL/min for several
minutes (Nano flow cells: Flush with pure HPLC-grade water with
the maximum possible flow rate for the respective range for
several minutes).
Check the lamp: If the lamp was newly installed, ensure that it is
installed properly. If the lamp is old (counting, for example, more
than 2000 operating hours), replace the lamp. See
Lamps
(

page 107) .
Install a different flow cell (see Installing a Flow Cell (
}
page 59) ).
Perform a validation. Perform a calibration and repeat the
validation again. If the message disappears with a different cell,
the flow cell that was previously installed may be clogged.
Code 7059 Calibration failed – values
outside specs. Remove and install the flow cell.
Flush the flow cell with pure HPLC-grade water with a flow rate of
>1 mL/min for several minutes (Nano flow cells: Flush with pure
HPLC-grade water with the maximum possible flow rate for the
respective range for several minutes).
If the error message persists, install a different flow cell or a
diagnostic cell (see
Installing a Flow Cell ( } page 59) ).
