• Turn the F-16 power on and verify the Count/Generate switch is in the
Generate position.
• Adjust the F-16 to the full-scale frequency as required by the application. To
compute the full-scale frequency, multiply (the number of discontinuities
sensed) by (the maximum speed) and divide by 60.
Hertz (frequency) = Number of Gear Teeth X RPM divided by 60
• Connect power source to DST-200C
• Turn power on to the DST-2000C.
• Verify that the CW relay energizes.
• Adjust the meter output potentiometer to obtain full-scale deflection on the
G-101 or 5 Vdc on digital voltmeter.
• Reverse the connections of the white and black leads of the transformer and
verify the CCW relay energizes and the CW relay de-energizes.
• Turn the F-16 power off and verify that the CCW relay de-energizes after
approximately 2 seconds.
