SITE PREPARATION REQUIREMENTS

The Model 204 Weight Indicator is a precision weight indicating instrument. As with any
precision instrument, it requires an acceptable environment to operate at its peak performance
and reliability. This section is provided to assist you in obtaining such an environment.
Environmental
The Model 204 Weight 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.
Do not place the indicator 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.

Electrical Power

The 204 indicator has been designed to
operate from a 100 to 240 VAC 50/60Hz
12 VDC 1A wall plug-in UL/CSA listed AC
power adapter (Cardinal part number
6800-1045).
 The socket-outlet supplying power to the indicator should be on a separate circuit from the
distribution panel and dedicated to the exclusive use of the indicator.
 The socket-outlet shall be installed near the equipment and shall be easily accessible.
 The wiring should conform to national and local electrical codes and ordinances and should
be approved by the local inspector to assure compliance.
 On installations requiring 230 VAC power, it is the responsibility of the customer to have
a qualified electrician install the proper power adapter plug that conforms to national
electrical codes and local codes and ordinances.
