4.15 Self-Diagnosis
The self-diagnosis function for analog measurement circuit is built in the ZM2376.
This function automatically runs at power-on, besides you can use it at your option.

Hardware failed Error message example
Press the _4_ key to start the self-diagnosis, and display the “Running” message.
The self-diagnosis function finishes after several seconds, and if there is no error, the “Passed”
message appears for a short time and the measurement screen comes back. It is impossible to
interrupt this diagnosis function.
The maintenance data on the top right shows the total time operated.
_SHIFT_ _EXP_ | [SYSTEM]
If there is an error, the following error message is displayed.
•Hardware failed Error of general measurement circuit
•Oscillator failed Error of drive signal source
•Analyzer failed Error of voltage/current measurement section
•HF failed Error of high-frequency internal impedance bridge
The serious error of measurement circuit can be detected by the self-diagnosis function. Slight error
cannot be found. To enhance the reliability of measurement, we recommend you to make a periodical
inspection such as starting inspection. The measurement of the DUT whose correct value was already
identified enables even the slight error to be detected. To make a critical measurement, it is preferable
to check before and after the measurement.
