8 Operation
Before using the sample changer, ensure that your laboratory environment provides
operating conditions that will prolong the life of the sample changer. Once the proper
operating conditions are met, you can load samples and start the sample changer sequence
run.
8.1 Establishing Optimal Operating Conditions
The sample changer operates reliably even under less than ideal conditions, however, it is
not indestructible. Malfunction or damage can occur if specific operating conditions are not
met. Meeting these conditions requires that you create the proper lab environment, replace
sample changer components that wear out under normal use, and purchase the appropriate
supplies for use with the sample changer. The following sections explain how to meet these
conditions.
Note: Damage or malfunction that results from unsatisfactory operating conditions may
constitute misuse and abuse and be excluded from warranty coverage.
To create satisfactory operating conditions in your laboratory environment, follow these
guidelines:
• Operate the system in a conventional laboratory environment where the temperature does
not exceed 80 °F (26 °C), the system is not exposed to condensing humidity, and the
system is not exposed to excessive flammable or corrosive materials.
• Avoid rough handling of the sample changer. If possible, do not expose the sample
changer to vibration or shock.
• Protect the sample changer from long-term exposure to condensation, corrosive materials,
solvent vapor, continual standing liquids, or large spills into the sample changer cabinet or
arm. Exposures of this type can damage the drive mechanisms as well as the electronics.
• Observe the same general electrostatic discharge precautions as with any other
integrated circuit electronic devices. Low humidity environments, especially when
combined with static-generating materials, require maximum care.
CAUTION
Static Discharge Buildup Hazard
Static discharge buildup may cause a short‑circuit or other material damage.
u Discharge static buildup and ground the device cabinet before performing any
maintenance.
u Do not touch or short‑circuit any electrical connectors.
• Avoid using the sample changer if strong electromagnetic interference, radio frequency
interference, or radioactivity is present. Interference fields can cause erratic operation of
the sample changer. The sample changer will not function properly if the level of
radioactivity is above background.
