Figure C-1 - Elastic Hysteresis EffectThe figure on page C-3 shows the hysteresis effect of clamping on a LaCosteG meter, after only 20 minutes of clamping.It is for such reasons that LaCoste gravimeter operators have learned to waitafter releasing the clamp (e.g. 5 minutes), and longer after reset (D meter), inorder to obtain higher reading repeatability.C-2CG-5 Manual - part # 867700 Revision 2
In the case of the CG-5, where the ruggedness of the inherent quartz elementallows us to dispense with clamping between readings, and its universalrange requires no resetting, we avoid the introduction of the hysteresis effectsdue to such causes. On the other hand, we allow the possibility of theirintroduction if the Autograv is left stationary off level, i.e. out of itsmeasuring range, for significant lengths of time.For this reason, it is recommended that whenever the Autograv is not beingtransported between stations, it should be leveled on its tripod so that themass and spring are in their normal configuration. When in transit, hysteresiseffects do not build up to any extent because the bipolar, high frequencychanges in tension on the spring effectively cancel out any tendancy for sucheffects to build up.Figure C-2 - Retardation effect after unclamping LaCoste Romberggravimeter G79, previous clamping time 20 minutes.
