instrument. This serial number should be visible in
Vision in Configure, Input.
6. Verify that the connector ends of the RJ-45 cable
are not damaged, crushed, or distorted in any
way. Wires should be firmly clinched by the
connectors.
Lamp does not come on when
instrument is connected.
1. Verify communication with instrument. Click on
Acquire, Disconnect, then Acquire, Connect, Select
DCM to verify proper connection. If lamp does not
come on, replace lamp according to instructions
provided in part 7.0 of this manual. Do not
attempt to replace lamp with AC power applied.
2. Lamp may be burned out. This should not occur
for thousands of hours of normal use, but could
be caused by jarring or other physical motion.
Replace lamp.
3. Instrument thermal shutdown may have occurred
due to high internal operating temperatures.
Determine cause of high temperature and correct
before subsequent operation. Service may be
required.
Instrument fails Wavelength
Linearization
1. Instrument Reference not in correct position.
Verify that reference paddle is visible in MultiVial
Analyzer sample window when a reference scan is
taken.
2. Instrumental problems – contact Metrohm service
or your authorized distributor.
Instrument Fails Performance
Test.
1. Verify that reference paddle is visible in MultiVial
Analyzer sample window when a reference scan is
taken.
2. Temperature and/or humidity may be changing
rapidly during the test. This can usually be
observed as large spectral activity between 1300-
1400nm and 1800-1900nm. If this is the case, the
instrument should be tested in a more controlled
setting to verify proper operation.
3. Instrument may be located on a bench with
grinders, stirrers, or other laboratory equipment
which produces vibration or mechanical
disturbance. This shows up as spectral activity in
various areas, depending upon the transmitted
frequency of the motion. Turn off all equipment
that might cause such disturbance. Locate it to
