5.4.2 Using Program Timers
Some procedures do not require the use of timers. Other
procedures require several timers. These timers are
pre-programmed into each Stored Program, along with a
description of the activity to be performed during the timed period.
1. Press the Timer icon on the display.
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: If you want to view the Program screen while the timer is
running, press Close. The time will be shown left side bottom instead
of the date.
Note: If necessary, you can also cancel the timer midway through the
countdown by pressing Cancel.
Note: The Timer will beep when the end of the running time is
reached.
A general purpose timer is also available in many programs.
Whenever you see the timer icon, you may press it and select
General Timer. A new screen will appear that allows you to enter
the length of the timed interval. Press OK to start the timer. The
timer will beep when the timed interval ends.
