NOTE
The individual components must be mounted with extreme caution. Any
damage to the contact surfaces, such as scratches or burrs, can affect
the accuracy of the force − proving instrument.
4 Conditions on site
4.1 Ambient temperature
The temperature effects on the zero signal and on the sensitivity are
compensated. To obtain optimum measurement results, the nominal (rated)
temperature range must be observed. Temperature
− related measurement
errors can be caused by heating (e.g. radiant heat) or cooling on one side. A
radiation shield and all
− round thermal insulation produce noticeable
improvements, but must not be allowed to set up a force shunt.
4.2 Moisture and humidity
External moisture and a tropical climate adversely affect transducer function.
Although the transducers and the mechanical loading fittings are made from
corrosion
− resistant materials, it is possible that the surfaces may change
color. This does not affect the metrological properties.
4.3 Air pressure
Air pressure changes act on the C18 − S1/1MN force transducer like a change
in force. Please note that pressure fluctuations offset the zero point. The
maximum zero point variation is 0.001% of the sensitivity at an ambient
pressure variation of around 10 mbar.
