If it drops significantly (typically down to just a few volts), then the problem is likely one of the HV transformers (T1 or T2) or the clock. Disconnect jumpers J29 and J30 (short wires next to the TIP120s). Turn on the 32-100 power and check for clock pulses at TP8, TP9, TP10, and TP11. If the clock is not detectable at any or all of these test points, then there is a problem in the clock circuitry. If the clock is okay, then test each transformer one at a time by connecting one of the jumpers, turning on the 32-100 power, and noting if the +17Vdc supply drops. Replace the transformer if it causes the +17Vdc supply to drop when its jumper is connected (J29 for the SED and J30 for the CMA).<\/li>\n<li>Another common problem involves the low voltage circuitry for each supply (drivers for E2 and E4). If these points are not at 300Vdc and cannot be adjusted, then the problem lies here. The most likely components to fail are the diodes, especially the 1N970s (CR19 and CR27).<\/li>\n<li><strong>Commonly needed <\/strong>repair parts:<\/li>\n<\/ol>\n<p>Transistors: TIP50, TIP120, MPF108, 2N3904<\/p>\n<p>Diodes: 1N970A, 1N972A,1N459A<\/p>\n<p><strong>CAUTION!<\/strong> Note that only personnel qualified to work safely with high voltage should perform these calibrations and tests.\u00a0 Voltages of up to 5,000V DC are possible in the 32-100 electron multiplier supply.<strong><br \/>\n<\/strong><\/p>\n<p>If you are unable to perform these tests RBD Instruments can repair your 32-100 electron multiplier supply and also provide a loaner unit if needed.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>32-100 Repair &amp; Calibration The 32-100 electron multiplier supply is used on many older PHI Auger and XPS surface analysis systems.
