Troubleshooting Tips
For additional information on troubleshooting, see the Instrument Performance Test Guide provided
with your Metrohm Analyzer
17.1 Instrument Error: Run Wavelength Linearization
Vision will some times report that Wavelength Linearization must be run. This describes the most
common causes, with a recommended course of action.
Most Likely Cause: Recommended Action:
Sampling module has been changed 1. Perform Wavelength Linearization
2. Run Performance Test
Instrument reference is not in the
proper position 1. Verify correct reference position
2. Verify nothing blocking beam
Lamp not turned on Click on Acquire, Disconnect, then
Acquire, Connect to re-establish
instrument communications
Sample left in instrument beam
(manual sample loading only) Remove sample from beam area
Correct the condition and run Wavelength Linearization, as described later in this section of the
manual.
17.2 Weak Signal
Most Likely Cause: Recommended Action:
Beam path is blocked Remove obstruction and retry.
This message is often associated with the Multi-Mode
or Sample Transport System. Verify the following
items:
Correct detector selected in Data Collection Method
(DCM)
Ceramic reference installed for reflectance use
Ceramic reference removed for transmission use
Sampling cell from previous analysis is not blocking
light path
