Site Preparation Requirements
The Attendant Bluetooth Weight Indicator is a precision weight indicating 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.
Environmental
The Attendant Bluetooth 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.
Ensure 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 Attendant Bluetooth Weight 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. Note that a special order is not required for operation
at 230 VAC.
• 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 ensure 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.
