继电器的主要技术参数如下：HT ADJUSTEMENT OF RELAY:Pick-up: 1100 VDC ±5% <30 ms.Drop-out: 850 VDC ±5% <30 ms.Maximum operating voltage: 1800 VDC (according to NFEN 50163).Primary supply voltage: 1500 VDC.
HT ADJUSTEMENT OF RELAY:
Pick-up: 1100 VDC ±5% <30 ms.
Drop-out: 850 VDC ±5% <30 ms.
Maximum operating voltage: 1800 VDC (according to NFEN 50163).
Primary supply voltage: 1500 VDC.
可是实际测试过程中：吸合电压有时高于1100V才会吸合，有时低于1100也吸合，这些值都不在±5%范围内。释放时要低于850才会释放，大概500V才释放，请问各位问题处在哪呢？
