 Test Scroll 5B (analog output #2).
 The analog inputs can be viewed in “Main Menu 3—Test Scroll 7.”
Here is the procedure for troubleshooting the Micro-Tech’s analog
input/output boards.
1. Confirm the DC mA voltage source.
 If GOOD—Proceed to “Confirm analog output” (see step 2). A
dual analog output board has individual power sources.
 If BAD—Replace either the analog board or the CPU board.
