4-2-9 Timer Test
1) Test contents
Adjust internal time to verify timer accuracy after a year.
In the simple test mode, the test is carried out at intervals of 5 seconds before and after 10 seconds in advanced test mode.
It verifies that there is no deviation between the estimated time of calculation and the actual acquisition time.
