Accordingly, a voltage proportional to the actual load by the orientation of the measuring shaft and the mass of the ﬁxture is output. This is not eliminated Using the external zero resetting function when the indication is reset to zero, but by adjustment described here, the output voltage when zero resetting is performed can be brought close to zero. ※For setting, connect the optional cable RZ-OP-2 to the gage and connect a In addition to the key provided on the gage, it is possible to reset the force digital voltmeter to the signal line corresponding to the analog output pin No. value to zero by inputting an external zero reset signal to the 26-pin connector Then, select this item by the setting procedure presented on page 9.
