Note
• The time duration of Graph R(t) is equal to the value of Timer 3.
• The Timer value could be very long (up to 99 minutes), so the Special automatic decimation
algorithm is use to write the Graph R(t) to the LCD.
• The cursors of the Graph R(t) could be activated with key
• The cursors of the Graph R(t) could be moved with and keys.
