1. Measure whether the plug and socket are in good contact.
2. Measure whether the electrode lead is open and whether the plug is soldered well.
Second, the electrolytic open circuit When the electrolytic open circuit, the measurement status display has instructions, the electrolysis status display only lights two green lights, "LED" digital display does not count.
At this point you should check the following conditions:
1. Electrolytic plugs and sockets are in good contact.
2. Whether the electrolytic lead on the cathode chamber is open or not, and whether the plug welding is good (when re-welding the plug, the positive and negative polarity should not be soldered wrongly).
3. Whether the welding points of the platinum and gold electrodes of the cathode and the anode are open.
Third, the measurement of short-circuit When the measurement of short-circuit, measurement, electrolysis status display no indication, LED digital display does not count. At this point you should check the following conditions:
1. Measure whether the plug or socket is short-circuited.
2. Measure whether the two ball ends touch with each other or whether they are short-circuited inside.
3. Measure whether the electrode is leaking. When the electrolysis time of the leaking instrument exceeds half an hour, it cannot reach the end point (this time it is not an electrolyte problem, replace the measuring electrode).
