SITE PREPARATION REQUIREMENTS

The Cardinal 210/215 indicators are precision weight-measuring instruments. As with any
precision instrument, they require an acceptable environment to operate at peak performance
and reliability. This section is provided to assist you in obtaining such an environment.
Environmental
The Model 210/215 indicators meet or
exceeds all certification requirements
within a temperature range of 14 to 104 °F
(-10 to +40 °C).
In order to keep cooling requirements to a
minimum, the indicator should be placed
out of direct sunlight and to provide
adequate air circulation, keep the area
around the indicator clear.
Make certain the indicator is not directly in
front of a heating or cooling vent. Such a
location will subject the indicator to
sudden temperature changes, which may
result in unstable weight readings.
Insure that the indicator has good, clean
AC power and is properly grounded.
In areas subject to lightning strikes,
additional protection to minimize lightning
damage, such as surge suppressors,
should be installed.
