Gauge Filament Replacement
Tungsten filaments have an emission life of one to three years in UHV. The life will be dependent on the residual gases present, range of pressures and vibration coupled to the filament. Tungsten filaments become brittle in use and the most common causes of fa...
Installation
Inspect the gauge structure before removing from the moulded clear plastic packing. Report any obvious damage to your AML Distributor before opening the moulded packing. Save the packing material, including the small foam plastic piece which restrains the flan...
Ion Gauge Cables
WARNING! The use of AML AIGLx cables is essential to achieve compliance with the EC EMC Directive, 89/336/EEC using AML and similar controllers. Extension cables are not recommended as these will prejudice compliance. 3, 6 and 9 metre cables are available, mod...
Ion Gauge Operation
New gauges must be operated carefully to achieve good results and long filament life. The filaments are under tension when new: run both filaments for a few seconds in emission to reduce and equalise the tension. Operate at low emission current in order to ou...

Repair and Refurbishment
Other than gauge heads returned under warranty it is generally not economically feasible to return damaged gauges for repair. Leaking feedthroughs cannot be repaired. Distorted grid structures and failed filaments are readily repairable by users. Any gauge he...
Gas Correction Factors
Gas correction factor tables are are only reproduced for the convenience of the user and do not imply that use with other gases will be safe with BA ion gauges. Divide sensitivity by 100 for Pa-1; multiply by 1.33 for Torr-1. Gas Symbol Gas...
Assistance
In the first instance, contact the distributor or supplier of the equipment. Always quote the serial number of the instrument and firmware and software versions. Provide a written description of the problem. If the problem is related to a motor or mechanism ma...
