For example. The 180 second cathode warm-up interlock circuit was validated by disconnecting and replacing the +12 VDC source with an external fused +12VDC power supply and powered up. If the circuit did not energize the required relay, well, there was more trouble shooting to do. The HV supply, the bias supply, the screen voltage supply, the antenna changeover circuitry, the metering circuitry, etc. were all independently validated. This made trouble shooting the integrated system easier knowing where the fault was NOT located.</div></td>
