Gyrocompass tuning
8.1.1.
GYRO ratio
- 360x, 240x, 180x, 90x, 60x, 36x
8.1.2.
GYRO sign
– direction of compass rotation:
positive, negative.
8.1.3.
GYRO type
– gyrocompass type:
selsyn, stepper.
Note
Again enter the current compass value during switching of stepper/ synchro compass
type.
8.1.4.
GYRO ref polarity
–
selection of reference signal polarity:
positive, negative.
as far as synchro type compass is concerned, selection of negative polarity causes
signal inversion and operation for signal edge shift by 180 degrees.
as far as stepper type gyrocompass is concerned, positive polarity corresponds to
high level and negative one to low level, which is used for determination of gyrocompass
working mode.
8.2
Log tuning
8.2.1.
LOG pulse/mile
– number of pulses per one mile.
100, 200, 300,
400, 500, 600.
Note
If log pulse repetition period at exact moment exceeds data update interval (1s), speed
is computed based on current measurement history following the last log pulse.
