小明利用最大刻度值标有2.5mL的一次性注射器等器材，对大气压的值进行测量，其实验步骤如下：
a．将活塞推至注射器底端，用橡皮帽封住注射器的小孔；
b．用细绳拴住注射器活塞的颈部，使绳的另一端与弹簧测力计的挂钩相连，然后水平向右慢慢地拉动注射器筒，如图所示．当注射器中的活塞刚开始滑动时，记下弹簧测力计的示数为7.5N；
c．测出注射器全部刻度的长度为4cm；
d．根据测量数据，算出大气压的值。

小明发现，同学们在做此实验时测得的大气压值误差较大，对此小明与同学找出了下列可能的原因： ①橡皮帽封住的注射器小孔中有残余气体； ②活塞与注射器筒壁间有摩擦； ③弹簧测力计的示数没有读准； ④活塞与注射器筒壁不完全密封。 上述原因一定会使测量值小于真实值的是（）
