Counter Measurement - Accurist 6W50 Operating Instructions Manual

Note: After 3 minutes, the 2/100th second hand will stop at the zero position to
preserve battery life; however, the time is still being measured to 2/100th
second and when the TR Button is pressed to stop the chronograph timing. The
2/100th second hand will automatically move to show that time.

Counter measurement:

1. Press TL Button while in normal mode. The 2/100th second hand acts as a
counter, with a maximum of 50 record counts.
2. Press BL Button twice to reset the counter.
