If 2500 ohms is not measured replace the resistor Should the resistor overheat or OPEN remove MT 1 and MT 2 and order the replacement Compensation Transformer from the factory If the resistance is 2500 ohms check all connections ensuring H1 Voltage is present at each compensating band that is selected If all these measurements are proper replace the kVp Meter Board The kVp Meter Compensation Resistor serves two purposes A The kVp Meter Compensation Resistor is parallel to the Autotransformer allowing immediate correction of kVp Meter Settings should line voltage fluctuate The fluctuation is normally no lower than 95 and no higher than 110 VAC This is the proper voltage range B The kvp Meter Compensation Resistor is connected for each mA Load by individual mA relays K1 through K7 C Contacts Compensation adjustments are for unit loss that occurs when current is moving in the high voltage secondary Because of loading kVp will decrease at the X Ray tube The bucking voltage selected from the 95 110 VAC supply bucks H1 to H2 Voltage The final Voltage difference is coupled to the kVp Meter allowing it to pre read the correct kVp that will appear at the X Ray tube The relationship of kilovoltage output to primary voltage input P1 P2 will not change unless the turn ratio of the high voltage transformer has changed due to a partial breakdown Partial breakdown occurrences are very rare Should you suspect a partial breakdown in the high
