seconds while its status LED (ALRM 1/1, ALRM 1/2, ALRM 2/1, or ALRM 2/2) is lit. When complete, rLy will be displayed for
4 seconds and then diSP will be displayed.
4.3.2 Chart Test - Chrt
Running the Chart Test will produce a test pattern drawn by the pens on the chart with the chart advancing.
After entering the test by pressing DOWN, the green pen will go toward the home position and the red pen will go toward the
outside of the chart. The chart will rotate at roughly 1 revolution every 1.5 minutes. Both pens will travel about 80% of the
chart in about 15 seconds, and then reverse their travel, and return to their initial position. This process will continue to be
repeated.
Depress any key to terminate the Chart test. The pen(s) will go to the home position and then Chrt will be displayed.
