Unknown condition Chadwick-helmet balancer model 177M-6A strobex 135M-11 with case avionics masters sales, service repairs 1001 NW 62nd street. Buy with confidence. We provide quality legacy avionics that our customers can rely on. Following their lead, the rest of general aviation bought in and yellow tags became part terminology culture. Sep 22, 2019.
The above diagram highlights the features of the 177M-6A and8350 balancers. Please note that if you intend to work with both airplanes andhelicopters, the Strobex must be included.
1. Power Cable - connects to the aircraft's 12or 28 VDC supply
2. Receptacles - for cable from transducer andmagnetic pickup from the left prop
3. Receptacles - for cable from transducer andmagnetic pickup from the right prop
4. Magnetic Pickup Switch -'independent' position creates two independent circuits enabling the user to record balance readingfrom two propellers in one 'run.' The 'common' position isused for helicopter work where two transducers are referenced to one magnetic pickup.
5. Function Switch - selects propeller trackfunction, or either left or right balance circuits
6. IPS Meter - shows vibration level
7. RPM Tune Dial - tunes the band pass filterto the RPM of the vibration
8. RPM Range Switch - multipliesRPM of the RPM tune dial reading by factors of 1, 10, and 100
9. Push For Scale #2 - when depressed, changesIPS meter sensitivity from 0 to 1.0 IPS to 1.0 to 10.0 IPS
10. Verify Tune Button - used in conjunctionwith RPM tune dial to adjust balancers band pass filter to the exact propelleror vibration frequency.
11. Interrupter Logic Switch - single positionis used for propeller balance work and the double position for most helicoptersmoothing
12. TestButton - verifies magnetic pickup signal and proper phazor operation
13. Phazor - reads phase angle (or clock angle)between transducer and magnetic pickup signals
