Test Display
Verifies that each segment of the display is functioning properly by
displaying a checkerboard pattern for several seconds and then re-
versing it. Press Enter to begin test or Cancel to quit.
Test Analog Out
Sets the signal on the analog output to an mA value corresponding to
any percentage of full scale for those outputs. Default percentage is
0% which sets the outputs to 4 mA. A different percentage from –15%
to +100% may be entered at the "New Value?" prompt. Figure 11 lists
the correct value of the 4 to 20 mA signal for various percentages.
Press Enter to begin test or Cancel to quit.
