Site Readiness
Like most precision instruments, the MasterLab Analyzer (RCA) is sensitive to environmental
conditions that can affect its performance and useful life. Observe the following guidelines when
selecting a site and installing the instrument:
2.1 Temperature and Humidity
The XDS MasterLab Analyzer is designed to work in ambient air temperatures from 40-95°F (4.5-
35°C).
Use the XDS Analyzer only in 10-90% relative humidity levels, non-condensing. Rapid changes in
humidity can cause interferences by adding trace moisture absorptions to the spectra. In general,
lower humidity levels are preferred.
The Performance Test (a comprehensive instrument diagnostic test in Vision software) is somewhat
sensitive to changes in ambient humidity, and the Performance Test may fail under conditions of
extreme humidity, or rapidly varying humidity.
2.2 General Environment
Minimize exposure of the monochromator to dust.
Inspect the fan filter at least monthly. If an accumulation of lint, dust, or other matter has
accumulated, pull open the right-hand panel from the instrument. Replace the filter. If dust has
accumulated on the fans, carefully wipe them clean with a moist soft cloth. Do not distort or damage
the fan blades or fins, as this will impede cooling.
Do not place the instrument directly near any HVAC duct. The direct flow of heating or cooling air
will cause the instrument to exhibit high noise during the Performance Test.
2.3 Vibration
Install the XDS Analyzer where it will not be affected by bench vibration from grinders, blenders,
stirrers, or mixers.
Never permit hammering or other physical impact on the bench top supporting the XDS Analyzer or
its computer.
2.4 Electrical Power
Power should be a single, separate, stable, transient-free filtered AC circuit. The circuit should have
surge protection.
Operating voltage for the instrument is 100-240VAC, 50/60Hz. The power supply is self-switching
and will provide the correct operating voltage to the instrument.
Maximum power consumption is 750W.
2.5 Instrument Communication
The XDS MasterLab Analyzer can communicate directly with the computer by use of a UTP Crossover
Cable (gray cable) supplied with unit.
Alternatively, the instrument may be accessed directly through a network connection. This uses a
