使用说明 Remarks |
1. 本产品为弱电流检测产品，传感器容易受运输、测试环境等因素影响，零点会有变化，但 2V 以内不影响传感 器的线性度。建议客户在使用本产品时，将传感器安装到系统待传感器稳定后进行零点测试，当零点偏大时，进 行软件校零处理。也可用 2.0 无感一字螺丝刀进行电位器调零，直至零点恢复正常；再将系统报警值设置在 2V。
This product is a weak current detection product, the sensor is easily affected by transportation, test environment and other factors, the zero point will change, but the linearity of the sensor will not be affected within 2V. When using this product, it is recommended that the customer install the sensor into the system and carry out zero test after the sensor is stable. When the zero is too large, the software should be used to correct the zero. The potentiometer can also be zeroed with 2.0 non-inductive flat-head screwdriver until the zero point returns to normal; Then set the system alarm value at 2V.
2. 错误的接线以及超出产品测量电流范围可能导致传感器损坏。
Incorrect wiring and out of the range of product measurement current may cause sensor damage.
