3. INSTALLATION
3.1 Site Preparation Requirements
The Cardinal Model 190 indicator is a precision weight-measuring
instrument. As with any precision instrument, it requires an acceptable
environment to operate at peak performance and reliability. This section
is provided to assist you in obtaining such an environment.
3.1.1 Environmental
The 190 indicator meets 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.
