Why is the chamber pressure very high when the stage is lowered in the Gatan PIPS II 695?
The chamber pressure might be high when the stage is lowered because there is a leak in the bellows. To resolve this, replace the bellows assembly.
What to do if the piston will not lower and backing pressure does not return within 5 Torr when pumping airlock in Gatan PIPS II 695?
If the piston won't lower and the backing pressure doesn't return within 5 Torr when pumping the airlock, the viewing port or window may not be seated properly, or there could be a VE valve failure. To address this: * Clean the viewport o-rings. * Press down on the viewport and window while pressing the Vac button (Maintenance > Vacuum). * Check the VE valve cable/control.
Why won't the shutter close or only closes partially on my Gatan PIPS II 695?
The shutter may not close fully due to an interrupted argon supply, a disabled HV timer, or a failure in the SI or SO valve. Additionally, the shutter piston may be clogged or have failed. To resolve this: * Ensure argon pressure is at 25 psi (1.72 bar) or that the main valve is open. * Verify the SI valve LED is on and the SO valve LED is off when the shutter is in. * Confirm the SI valve LED is off and the SO valve LED is on when the shutter is out. * Inspect the SI and SO valve cable/control. * Clean and inspect the shutter piston.
What to do if piston cannot be lowered into the chamber, but backing pressure does return within 5 Torr when pumping airlock Gatan PIPS II 695?
If the piston cannot be lowered into the chamber, but the backing pressure does return within 5 Torr when pumping the airlock, it may be due to an interrupted argon supply or a WL or LL valve failure. To resolve this: * Check that the argon pressure is at 25 psi (1.72 bar) or that the main valve is open. * Check the WL and LL valve cable/control, ensuring the WL valve LED is illuminated and the LL valve LED is not illuminated.
What causes poor vacuum when specimen mount rotation is operated in Gatan PIPS II 695?
Poor vacuum during specimen mount rotation, often indicated by periodic pressure bursts, is typically caused by a dirty or dry quad-ring in the Whisperlok piston. Cleaning and lubricating the piston quad-ring should resolve this issue.
What to do if the ion gun has no output on my Gatan Ultrasonic Jewelry Cleaner?
If the ion gun has no output (current=0, voltage on, gas on), it may be shorted (anode cup to magnet). Clean the guns to resolve this.
How to fix specimen that will not rise fully into the airlock in Gatan PIPS II 695?
If the specimen will not rise fully into the airlock, the airlock vacuum seal may be dry and coated. Servicing the vacuum seal should solve this problem.
Why is the chamber pressure display 0 on the Milling screen of my Gatan PIPS II 695 Ultrasonic Jewelry Cleaner?
A chamber pressure display of 0 on the Milling screen can be caused by several factors: * MDP not up to speed. * Manual vent valve open. * Vacuum leak. * MDP failure. * DP failure. To troubleshoot: * Turn off gas flow. * Verify MDP speed (Maintenance > Vacuum).
Why is the gun output extremely erratic on my Gatan PIPS II 695 Ultrasonic Jewelry Cleaner?
If the gun output is extremely erratic, it may be because the guns are not purged sufficiently. Purging the guns should resolve this issue.
What causes excessive argon use in Gatan PIPS II 695 Ultrasonic Jewelry Cleaner?
Excessive argon use is typically due to an argon leak. Check for leaks to resolve this.
