II.VALUE CHECKING AND ADJUSTMENT
●Resetting the stopwatch hands to “0” position
Repeat “START” – “STOP” – “RESET” of the stopwatch several times to check if each of the three stopwatch hands returns to “0” position securely.
●Checking the time period of date change
Specified time period of date change: 0:00 a.m. ~ 0:03 a.m.
With the crown at the second click, advance the hour and minute hands until the date changes. Check if the date changes within the time period specified above.
●Remarks on measuring time accuracy
To measure the time accuracy, be sure to reset the stopwatch to “00”. If the accuracy measurement is made while the stopwatch is counting, stable measurements may not be obtained.
●Current consumption
Current consumption measurement of Cal. 9T82A requires special tools, and the movement could be damaged during the procedure of current consumption measurement. We do not recommend, therefore, that you measure the current consumption for checking. It can be assumed that the current consumption is within the standard range as long as the movement is kept under proper conditions.
