
] key to select the “ Tach Filter Type ”. The options are for a Single pole
filter, a Double pole filter or None.
9.1.2.7. Use the keypad to enter the “ Tach Filter Frequency ”. Enter a numeric value equal
to the lowest frequency of interest. The filter will then be effective for that frequency
and all frequencies above that value.
9.1.2.8. Use the [

] key to select the “ Full Scale Vibration ”. This should be the highest
amplitude of vibration you would reasonably expect to see during a typical balance
job. This value should be enough above the maximum allowable vibration for the
engine so that any amplitude in excess of that value can be readily seen. Use the [

]
key to move to the next field.
9.1.2.9. Use the [

] key to select the “ Sensor Type ” you will use for this balance. If the
sensor you intend to use is not among those listed, see Chapter 22, Analyzer
Management to learn more about adding sensors. Use the [

field.
9.1.2.10. Use the [


the sensor input from the vibration sensor in this same row. Use the [

] key to move
to the next field.
9.1.2.11. Use the keypad to enter a name in the “ Desc ” field. The name should reflect the
source, location, or other common attribute of this sensor input. Some suggested
examples are: FRONT, REAR, VERT, HORIZ, or FFV, FFH. Use the [

] key to
move to the next field.
9.1.2.12. In the “ Pos ” field, use the [

] key to select the clock position of the sensor on the
engine as viewed from forward of the engine looking into the intake.
9.1.2.13. When all fields are completed as required, press [OK] to accept and proceed.
