What to do if there is no output when the ESU Unit is started and turned on?

The ESU Unit has long been widely used as an electrical surgical equipment in surgery. Once there are problems with the ESU Unit during surgery, 

it will inevitably affect the surgical process. If you encounter a sudden lack of output, don't worry, this situation may not necessarily be a problem with the device:

Is there electricity in the power socket (or cable tray)?

Is the main power cable disconnected?

Is the power fuse of the electric knife blown due to long-term oxidation?

Has the power switch been properly closed?

The above checks may seem relatively low-level, but in reality, they are quite common. 

Only by eliminating these issues can problems be solved more quickly

Has the polar plate alarm been eliminated?

Check if the connection port between the electric knife pen and the high-frequency electric knife host is loose, as most disposable electric knife pens are used now, 

and prolonged insertion and removal can easily cause loosening of the device interface.

Is the start switch (manual or foot operated) connected to the machine, and is it damaged or the lead broken?

Are there any broken wires in cables such as hand controlled knives, foot controlled knives, or tweezers?

Is the foot switch inserted in the wrong position?

If there is still no output after excluding the above, it is a host fault
