The above diagram highlights the features of the 177M-6A and
8350 balancers. Please note that if you intend to work with both airplanes and
helicopters, the Strobex must be included.
1. Power Cable - connects to the aircraft's 12
or 28 VDC supply
2. Receptacles - for cable from transducer and
magnetic pickup from the left prop
3. Receptacles - for cable from transducer and
magnetic pickup from the right prop
4. Magnetic Pickup Switch -
"independent" position creates two independent circuits enabling the user to record balance reading
from two propellers in one "run." The "common" position is
used for helicopter work where two transducers are referenced to one magnetic pickup.
5. Function Switch - selects propeller track
function, or either left or right balance circuits
6. IPS Meter - shows vibration level
7. RPM Tune Dial - tunes the band pass filter
to the RPM of the vibration
8. RPM
Range Switch - multiplies
RPM of the RPM tune dial reading by factors of 1, 10, and 100
9. Push For Scale #2 - when depressed, changes
IPS meter sensitivity from 0 to 1.0 IPS to 1.0 to 10.0 IPS
10. Verify Tune Button - used in conjunction
with RPM tune dial to adjust balancers band pass filter to the exact propeller
or vibration frequency.
11. Interrupter Logic Switch - single position
is used for propeller balance work and the double position for most helicopter
smoothing
12. Test
Button - verifies magnetic pickup signal and proper phazor operation
13. Phazor - reads phase angle (or clock angle)
between transducer and magnetic pickup signals
