P0305 Rev Gyroscope High Voltage to Ground Plane Test P0305 Rev. - Purpose: To test coated electrodes and ground plane for no continuity Materials and Supplies: • High Voltage power supply, calibrated to manufacturer’s specifications. • Keithly Model 617 Electrometer, calibrated to manufacturer’s specifications. • High vacuum test facility conforming to Stanford / NASA guidelines • Approved qualified personnel performing test battery • Traveler notebook for Gyro currently in Test. • Record data in GP-B Database in Gyro Coating and Testing Traveler Process: Test Set-Up: Refer to High Voltage to Ground Plane Set-Up diagram on page 2. For each electrode: 60 Ramp power supply to 1500 VDC in 100 V increments with a delay of ~ 30 seconds between voltage increases. Maintain 1500 VDC for > 60 minutes. After minutes, increase the DC voltage to 2000 VDC in 100 V increments. Hold the voltage at 2000 V for ~ 5 minutes, then ramp voltage down to 0 volts. Current should be < 20pA at 2000VDC for each electrode. Record voltage and current in P0305 Table 1 for each electrode.
