8.2 General Alignment Conditions
Perform all adjustments under the following conditions:
• AC voltage and frequency: 230 V_ac / 50 Hz.
• Connect the set to the mains voltage via an isolation
transformer with a low internal resistance.
• Allow the set to warm up for approximately 20 minutes.
• Measure the voltages and waveforms in relation to chassis
ground (with the exception of the voltages on the primary
side of the power supply). Never use the cooling fins /
plates as ground.
• Test probe: Ri > 10 Mohm; Ci < 2.5 pF.
• Use an isolated trimmer / screwdriver to perform the
alignments.
