CORRECTIVE ACTION
Step 2:
Check for bad capacitor Cl (Output Meters TS-585A/U and TS-585B/U only).
See paragraph 6-9 for test and replacement procedures.
Step 3:
Check for bad autotransformer.
See paragraphs 6-18 for testing procedure
6. Meter indication too low when impedance control is set at 400 ohms or above (at 1,250
or above for Output Meters TS-585C/U and TS-585D/U).
Check for poor contact or no contact of wiper arms on rings of impedance control
See paragraph 6-20 for cleaning and adjustment procedures.
7. Meter indication too high at all positions of impedance control.
Step 1:
Check for poor calibration of output meter.
See paragraph 6-26 for calibration procedures.
Step 2:
Check for bad rotary switch contacts.
See paragraph 6-22 for testing procedures.
Step 3:
Check for bad radial resistors R12, R13, or R14.
See paragraph 6-11 for test and replacement procedures.
Step 4: Check for bad axial resistors R4, R5, or R6.
See paragraph 6-13 for test and replacement procedures.
Step 5:
Check for bad meter.
See paragraph 6-16 for testing procedures.
