表指示器应当是平衡式的并有微调，这样零点漂移可以不用调节可动元件来修正。
Gauge Pointers shall be balanced and provided with a micrometer adjustment so that zero shift may be corrected without adjusting the movement.
零点和间隔调整，是由前面板的25转微调直接产生的。
Zero and span adjustments are made directly from the front panel with 25-turn trim pots.
微调移动X轴接近“十”字比较尺，直到数字比较器的指示灯在零点右边变亮。
Move with the X axis micrometric movement the sharp shadow, till the digital comparator red light is on the zero right position.
