Chapter 4
Revision 2.2, Apr 2020
4.1.1.1.18.
Using the [
] key, move to the “Tach Pos (FLA)” field for Eng 2. Using the [
]
key, select the tach position. The tach position is determined by standing Forward
of the propeller Looking Aft (FLA) toward the tail of the aircraft. From this
viewpoint, determine the approximate clock position (1:00 to 12:00) of the
tachometer pickup.
CAUTION
Sensors connected to Channel A and Channel B (or Channel C and Channel D in the Viper II) must
be of the same type. Using different sensors during the same job will cause erroneous readings
and problems achieving good balance results.
4.1.1.1.19.
Move down to the “Sens Type” field using the [
] key. Select the sensor type
from the available options using the [
] key. If your sensor type is not listed, see
section Paragraph 4.1.1.3 of this manual entitled “Sensor Setup.”
NOTE
Sensor Channels C & D are only available on the Viper II
4.1.1.1.20.
Move to the next field, “Sens Chan” for Eng 1 using the [
] key. Select sensor
channel “A, B, C, D, A&B or C&D” according to which of the analyzer’s input
channels you intend to use. The default for single-sensor input is Channel A. Use
the [
] key to make the selection. If you are conducting a two-sensor balance,
choose A&B or C&D.
4.1.1.1.21.
Move to the next field, “Sens Chan” for Eng 2 using the [
] key. Select sensor
channel “A, B, C, D, A&B or C&D” according to which of the analyzer’s input
channels you intend to use. The default for single-sensor input is Channel B. Use
the [
] key to make the selection. If you are conducting a two-sensor balance,
choose A&B or C&D.
4.1.1.1.22.
Using the [
] key, move to the “Sens Pos (FLA)” field for Eng 1. Using the [
]
key, select the vibration sensor position. The sensor position is determined by
standing Forward of the propeller Looking Aft (FLA) toward the tail of the
aircraft. From this viewpoint, determine the approximate clock position (1:00 to
12:00) of the vibration sensor.
4.1.1.1.23.
Using the [
] key, move to the “Sens Pos (FLA)” field for Eng 2. Using the [
]
key, select the vibration sensor position. The sensor position is determined by
standing Forward of the propeller Looking Aft (FLA) toward the tail of the
aircraft. From this viewpoint, determine the approximate clock position (1:00 to
12:00) of the vibration sensor.
