Frequently Asked Questions
Here are a few questions we get asked frequently. Hope this answers some questions you may have.
Q: My scale is weighing light and will
not return to zero or repeat in weight. Is there anything I can look
for or do before you come out and service my scale?
A: Yes, you can look for debris (wood, ice/snow build-up, mud,
rocks, etc...) Make sure the scale is not touching anywhere or
anything. Make sure the ramp has not come loose and is now hindering
the scale.
Q: My scale is drifting in weight. What
should I do?
A: Schedule a service call. In most cases we can be there the same
day. This can be caused by a number of things
our expert technicians can diagnose. The most typical are: cut/chew
in a cable, moisture in junction box or indicator, and/or electronic
interference.
Q: What is a load cell and how does it work?
A: A load cell is an electronic device that is used to convert a
force into an electrical signal. This conversion is indirect and
happens in two stages. Through a mechanical arrangement, the force
being sensed deforms a strain gauge. The strain gauge converts the
deformation (strain) into electrical signals. The electrical signal
output is typically a few millivolts and requires amplification by
an instrumentation amplifier before it can be used. The output of
the transducer is plugged into an algorithm to calculate the force
applied to the transducer.
