3-4 Functions of Self-diagnostic Harness

The harness short-circuits the input and output terminals of the meter in advance, switches the respec-
tive inputs of the meter ON and OFF in sequence, and checks if the data on the output side is normal.
Check if the signal changes in synchronization
with the output when the power is turned ON.
Goes into aging mode.
Always select input mode.
Check that the input potential is inverted with the
transistor turned ON and OFF.
