2.Press OK to start the first timer.

The timer will count down on the screen.

3.To start the next timed activity for the Stored Program, press the Timer icon and OK.

Note: Press Close to view the measurement screen while the timer is running. The time will be shown left side bottom instead of the date.

Note: Press Cancel to stop the timer midway through the countdown.

Note: The Timer will beep when the end of the running time is reached.

A general purpose timer is also available in many programs. When the timer icon is visible, press the icon and select General Timer. A new screen will appear. Enter the length of the timed interval and press OK to start the timer. The timer will beep when the timed interval ends.
