Operating procedure
Boot sequence
Open the compressor power supply and check that the secondary pressure is 5.0 bar. Turn on the water supply and adjust the water flow pressure to 4 bar. Open P10 gas and set the secondary pressure to 0.7-0.8 bar. If a flushing system is configured, open He gas and set the secondary pressure to 0.8 bar. Turn on the main power switch of the main unit to put the main unit in standby mode. Turn on the “POWER ON†switch to put the host in the “on†state. Open the computer, run the analysis software, and the username and password are “SUPERQâ€. Check the instrument vacuum (less than 100Pa?), P10 gas flow (about 1L/Min). When the high voltage switch is turned on, the instrument automatically sets the high voltage to 20kv/10mA. Check water flow, internal circulating water (3-5L/Min), external water (1-4L/Min). Wait for the internal temperature of the instrument to stabilize (30 degrees) for normal analysis.
2. Downtime
Gradually reduce the high voltage to 20kv/10mA. Turn off the HT high voltage. Take the analysis software offline with the host. Press the “POWER OFF†switch and the instrument is turned off. If the instrument is not used at night and on weekends, it is recommended to set the high voltage to 20kv/10mA low power state, low power state, it is recommended to set the high voltage to not shut down. Do not shut down. X3. X-Ray Tube Aging If the main engine is down for more than 24 hours, the X-Ray Tube needs to be aged.
3. Manual aging
Run the TCM4400 after booting in the following order: 20kv/10mA→30kv/10mA→40kv/10mA→50kv/10mA→60kv/10mA→24kv/100mA→40kv/60mA→50kv/48mA→60kv/40mA If the downtime is greater than 24 The hour is less than 100 hours and the dwell time per step is 1 minute. If the downtime is greater than 100 hours, the dwell time per step is 5 minutes. Automatic aging After running the TCM4400, if the downtime is greater than 24 hours and less than 100 hours, select “Fast†aging. If the downtime is greater than 100 hours, select “Normal†aging.
