故障分析与排除：

Symptom	Cause	Remedy	Note
No Display on Startup	1) Power not connected	Connect Power	Replace fuse with same model — no substitutions.
No Display on Startup	2) 5A fuse not installed or open circuit	Reinstall or replace fuse.	Replace fuse with same model — no substitutions.
输出电流达不到100A	1) Test leads too long or cross-section too small	Replace with larger gauge wire.
No Current Output	1) Device under test is open circuit	Check Equipment Troubleshoot
No Current Output	2) Open circuit in test loop	Check test loop and eliminate open circuit.

Precautions

打开电源开关之前，应先将电流调节钮按逆时针调至“零位”。仪器应放置于干燥、通风，无腐蚀性气体的室内。

运输、贮存
