Figure 3-13 – Auxiliary VDI Test Page
When on the appropriate page turn the large, outer knob to select the desired VDI deviation test. The test
is initiated as soon as it is selected. There are five VDI tests in the following order:
•
VDI Triangle Test: gradually drives the VDI needle up and then down
•
VDI Down Test: drives the external VDI needle full scale down (i.e. output set to 150mV down)
•
VDI Mid Test: drives the external VDI needle to center (i.e. output set to 0mV)
•
VDI Up Test: drives the external VDI needle full scale up (i.e. output set to 150mV up)
•
VDI Manual Test: allows manual input of VDI outputs (from 10D to 10U in 15mV steps, with 10
corresponding to a full scale output of 150mV, and 0 corresponding to the center)
As a minimum, perform the DOWN, MID and UP tests for the vertical deviation needle of each CDI
connected to the CNX80.
