Grounding the Scale Base
Bench scales can build up static electricity charge during weighing operations. If powerful enough, this charge can
travel through the load cell cable to the indicator. To prevent this, all bench scales should be adequately grounded
so that static charges and transient electrical surges can drain directly to the ground. A recommended practice is to
connect the scale base to an AC ground circuit using at least #12 wire. All Benchmark series scales have either a
grounding screw or a hole for such a grounding screw located on the bottom of the lower frame for this purpose.
