OPERATION NOTICE
1. The machine should have good grounding with grounding resistance<4
Ω
.
2. The machine adopts high performance, high reliability, and steady voltage
switch power supply. It has constant voltage overflow protection and can work
in 220 VAC electric network. The micro-processor can monitor the output DC
voltage. If the Fuse is melted broken, it will show that the machine’s inner
parts has occurred problems.
3. In order to make sure reflect loss is
≥
45dB, we use SC/APC connector; other
type (such as FC/PC) cannot match with it. Keep the connector clean when
