The relay protection test box is controlled by microcomputer, and the operation is prompted by Chinese characters.
继电保护试验箱采用了微机控制，汉字提示操作。
The machine also has a self-check error report function, the machine immediately put in self-test after starting, greatly convenient inspection and maintenance.
本机还设有自检报错功能，开机后本机立即投入自检，极大地方便了检查、维修。
Such as "pull voltage", "off voltage", "normal open pull time" and so on.
如“吸合电压”、“断开电压”、“常开吸合时间”等。
The instrument also has the advantages of beautiful appearance, reliable performance, easy operation, complete functions, etc. It is an ideal testing instrument for verifying relay protection devices.
仪器还具有外形美观，性能可靠，操作简便，功能齐全等优点，是校验继电保护装置理想的检测仪器。

继电保护试验箱测试方法
Turn on the power switch and the display displays "Welcome to....".
打开电源开关，显示屏显示“欢迎使用....”
, "Self-checking...."
,“正在自检....”
, microcomputer self-test, self-test normal, display "self-test complete!"
，微机自检，自检正常后，显示“自检完毕！”
.
。
When measuring, the type of test power supply should be selected according to the type of relay to be measured with the two keys of "upturn" and "downturn", so that the status display corresponds to the type of relay to be measured.
测量时，应根据所测继电器的种类，用“上翻”和“下翻”二键选择测试电源的类型，使状态显示与被测继电器种类相对应。
The relay coil is connected to the corresponding power output terminal, and the relay contact is connected to the input terminal.
并将继电器线圈接入相应的电源输出接线柱，继电器触头接入输入端子。
1, measurement: press the "measurement" key, the machine can measure the suction, disconnect the voltage (flow) value three times, and then press the "print" key to print the data.
1、测值：按“测值”键，本机可测吸合，断开电压（流）值三次，然后，可按“打印”键打印数据。
2, measuring time: first find the rated value of the relay to be measured, and then press the "measuring time" key, the machine automatically divided, closing test three times, disconnect time, after the end, you can press the "print" key to print data.
2、测时：先找出被测继电器的额定值，然后按“测时”键，本机自动分、合闸测三次吸合、断开时间，结束后，可按“打印”键打印数据。
