14.

Plug the instrument back in to AC
power. Turn the AC power switch to
ON.

15.

Connect to the instrument through
Vision software.

Verify that the Lamp LED (green, upper
right) illuminates.

Let the instrument warm up until the
“Ready” LED (green, middle LED on
lower row) illuminates to indicate that
operating temperature has been
reached.

16.

Perform Wavelength Linearization and Instrument Calibration. Run Performance Test. If all
tests pass, the instrument is ready for operation.

Always keep a spare lamp in stock, to avoid last-minute emergencies. If you do not have a
spare lamp after changing this lamp, order one from your Metrohm distributor
immediately.

NOTE: The lamp is a very special assembly, and should never be replaced with any substitutes.
Special features of the lamp include (but are not limited to) the following:

•

Hand-selected for high-energy filament placement

•

Coated internally and externally for maximum NIR performance

•

Welded wire connectors to minimize resistance and assure consistent illumination

•

Tested for low-noise spectroscopic performance

Fuse Replacement

Fuse Replacement is an unusual event, and usually is caused by some electrical fault. The electrical
fault should always be investigated and repaired before fuse replacement. Once the fault is found
and corrected, this procedure should be followed:
