There are three main types of high frequency electric knife alarms:

1. Self-starting when power on, if there is an internal fault that makes it impossible to boot or the output circuit is abnormal, the machine will alarm.

2. If the selection of single-piece neutral electrode and double-piece neutral electrode is wrong, the machine will also alarm. For example, if the single-piece electrode is connected, the double-piece electrode is selected.

3. After the double-plate neutral electrode is selected, the electrode is in poor contact with the patient, which causes the machine to automatically alarm.

You can judge where the problem is based on the above three types. If it is the first type, you need to ask the manufacturer for consultation and maintenance.
