Environmental
The Cardinal 212G/212GX indicators meets or exceed all certification requirements within a
Temperature range of 14 to 104 ºF (-10 to +40 ºC)
In order to keep cooling requirements to
a minimum, the indicators should be
placed out of direct sunlight and to
provide adequate air circulation, keep
the area around the indicators clear.

directly in front of a heating or cooling
vent. Such a location will subject the
indicators to sudden temperature
changes, which may result in unstable
weight readings.
Insure that the indicators have 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.
