may also assign colors to the pen traces on the Real Time plot by tapping on the color tiles
associated with each of the four pens. When you tap on Done after completing the Plot Setup, you
will see the Real Time trend of the tags you assigned to the four pens. The left hand end of the

stop the real time trend by tapping on the Stop button or switch to Main Menu by tapping on Menu
