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...

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 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...

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...

In the European Union (EU), waste from electrical and electronic equipment (WEEE) is now subject to legislation designed to prevent the disposal of such waste and to encourage proper treatment measures to minimize the amount of waste ultimately disposed to lan...

To comply with the EU WEEE Directive, the UK government has implemented the Waste Electrical and Electronic Equipment Regulations 2006 (Statutory Instrument 2006 No. 3289). AML is providing a product take back process to cover, treatment, recovery and disposal...

AML products sold in EU countries, other than the UK, are sold through distribution networks. Distributors outside the UK effectively become importers and as such are the ‘Producers’ of AML products within the scope of the EU WEEE Directive. Our distributors w...

If you have purchased AML-branded electrical or electronic products in the UK on and after August 13, 2005, and are intending to discard these products at the end of their useful life, please do not dispose of them with your other household or municipal waste....

Historical waste is defined as WEEE purchased before August 13, 2005. End of life AML branded historical WEEE. The WEEE Directive does not legislate that AML, as a ‘producer’, shall collect ‘end of life’ historical WEEE of its own brand, unless it is being re...

#1.1. Charges Please contact AML for the latest repair charge. Return carriage is extra, at cost. We will use your carrier at no extra charge. Packed instruments weight 6.5 kilograms. #1.2. Procedure Ensure that there is a fault on the AML product. Th...

#2.1. What instruments can be repaired? PGC1, PGC2, PGC2D, NGC2, NGC2D, NGC3 & SMD210 instruments that are less than 20 years old. Serial numbers starting with a letter corresponding to the year of manufacture: Nxxx yyy = 2003 Oxxx yyy = 2004 Pxxx yyy = 2...

The SMD4 offers 3 communication interfaces, USB, Ethernet and Serial. The serial interface is dual mode, and can be configured for RS232 or RS485. Multiple interfaces can be connected and in use at the same time (AML Device Control software allows you to conne...

A simple text-based protocol is used. Commands are sent to the SMD4, checked and executed, and a response returned. Data are buffered on receipt and commands are evaluated and executed on a first in first out basis. Although not a requirement, it is usually ea...

AML stepper motors are specifically designed for use in UHV environments making them ideally suited for low-speed precision in-vacuum manipulation. The model D motors are two phase hybrid stepper motors, available in a range of standard sizes and torque rati...

AML motors are vacuum sealed packaged. Wear gloves to remove the motor from its vacuum packaging. Once removed it must be stored in a cleanroom or clean, closed container.

Use the extended screws for mounting but do not adjust them. Take normal vacuum precautions, avoid creating trapped volumes when mounting the motor and obstruct as few as possible of the pumping holes in the end faces. The location spigot projecting from the f...

The preferred method of coupling a load to the shaft is by a setscrew or collet fixing. AML do not recommend users modify shafts.

Motors are supplied pre-baked to 200 °C in 1 x 10-6 mbar pressure for 24 hours and vented with dry Nitrogen before vacuum packaging. They may still adsorb water in storage and handling so a 24-hour bake by an AML stepper motor drive, with an adequate pump is r...

These motors are specifically designed for use in conjunction with AML stepper motor drives current-regulated switch-mode drive. If another drive is used it must be a bipolar 2-phase drive and capable of providing a selection of well-regulated currents of less...
