14. 2 Thus parameters such as the Averaging Time will affect the results Obviously the value of the stimulus must be as stable as possible during the measurement of in order to make an accurate zero adjustment Y A new value of L is redefined each time the zero adjustment function is activated The new value replaces the preceding one and becomes the current value of Leo To look for the current value of Leo use the offset adjustment OFFS function with nternal Unit see section 3 1 3 2 Y Despite the fact that the zero adjustment is active only on the selected measuring channel this function is transducer specific that is the resulting value of L will be associated to the 17 UMI OPERATING MANUAL EPROM version 6 1 x REV 03 09 16 Gauge Factor not to the selected channel In other words the Gauge Zero is always linked to the Gauge Factor even though the later is re assigned to another channel Note that removing a Gauge Factor from the Gauge List will erase its Gauge Zero as well Y The zero adjustment function is automatically disabled in the case of a temperature transducer Y The zero adjustment should be performed when the strain gauge force amp load refractive index or gauge pressure transducers are being used for the first time for absolute pressure see section 3 1 3 2 Y It is recommended to take note of the current value Lero when doing a zero adjustment Knowing that it is possible to re enter an arb
