1. The relay status is closed from factory,but cause the shock or any other external force factors,the status may be changed,so pls reset as closed status when using need.
2. In order to ensure the relay effective opening or closing,the driving voltage which brought to coil must reach within the regulation rated voltage range,dont give the drop-out voltage and pick-up voltage at the same time. when give voltage to coil,the time must Slightly more than relays actuation time(＞*0ms),also cant longer than one minutes;
3. While the relay leading-out terminal be out of shap then cant be installed in ammeter cause any external force,dont force install them into ammeter by nobbing,though force install success,the result is influence ammeter work normal.
