    AMH-100 is compatible with PG7201, PG7202, PG7302 and PG7307 Platforms and handles a mass set of nominally 40, 60, 80 or 100 kg. It does not include a vacuum chamber so the masses are always in ambient pressure conditions.

  • Page 15: Site Requirements

    GAS SUPPLIES AMH-38 requires a compressed air source and a vacuum source (see Sections 2.2.2.1, 2.2.2.2). AMH-100 requires a compressed air source only (see Section 2.2.2.1). 2.2.2.1 DRIVE AIR SUPPLY The drive air supply provides power to operate the mass lifter and the binary mass selector pins (see Section 3.1).

  • Page 16: Vacuum Supply (Amh-38 Only)

    AMH-38™ AND AMH-100™ OPERATION AND MAINTENANCE MANUAL 2.2.2.2 VACUUM SUPPLY (AMH-38 ONLY) The vacuum supply is necessary for AMH-38 operation when there is vacuum in the AMH-38 vacuum chamber and bell jar (absolute by vacuum mode PG7601 operation). The vacuum supply assures that the binary mass selection pins remain in the correct position and evacuates internal AMH volumes to minimize the likelihood of leaks into the reference vacuum.

  • Page 17: General Considerations

    SETTING UP THE AMH FOR OPERATION 2.3.1 GENERAL CONSIDERATIONS AMH-100 requires only three connections: drive air supply, electrical power, and RS232 cable for communications with PG7000 Platform. Consider these connections when setting up the AMH-100. AMH-38 requires at least three connections: drive air supply, electrical power, and RS232 cable for communications with PG7000 Platform.
  • Page 18 AMH-38™ AND AMH-100™ OPERATION AND MAINTENANCE MANUAL To use the supplied accessories to make the AMH drive air supply connection proceed as follows: Connect the quick-connector to one end of the PFA tube. Loosen the 1/8 in. Swage nut on the assembly slightly. Slip the PFA tube into the nut until it stops.

    When power is connected, the green LED near the electrical connector should light and not flash. If the LED flashes, see Section 3.2.7. If the LED doesn’t light, and you are sure power is connected, contact your DHI Authorized Service Provider. Page 11 © 2007 DH Instruments, a Fluke Company...

    The other cases contain the main masses of 6.2 (AMH-38) or 10 kg (AMH-100) (see PG7000 Operation and Maintenance Manual, Inspecting Contents, Mass Set for mass set composition detail). Each mass is packed in a sealed plastic bag and then placed in a protective shipping insert.

    SHOWN IS THE MS-AMH-38 MASS SET FOR THE AMH-38 MASS HANDLER. SMALLER MASS SETS MAY INCLUDE LESS MAIN MASS DISCS. MASS SETS FOR THE AMH-100 MASS SET ARE IDENTICAL TO AMH-38 BUT THE MAIN MASSES ARE LARGER 10 KG DISCS AND A 7TH BINARY MASS TUBE OF 6.2 KG IS INCLUDED.

    (see Section 3.1). When this step is complete, the AMH mass handler is ready to be installed on the PG7000 Platform (see Section 3.2.1). Page 17 © 2007 DH Instruments, a Fluke Company...

    Numerical reference in this section refers to Figure 8. The purpose of the AMH-38 or AMH-100 system is to automatically load specified values of mass onto the PG7000 piston. This is accomplished by lifting the complete mass set up off and above the piston- cylinder to the mass selection position, selecting the individual masses to be loaded and retained, and then placing the masses to be loaded back onto the piston.
  • Page 28 AMH-38™ AND AMH-100™ OPERATION AND MAINTENANCE MANUAL 4. Binary mass tube selection pins(3): The binary mass selection pins are used to retain the binary mass tubes that are not to be loaded onto the piston. Three pins for each mass are located in a circular pattern around the top of each mass.

    AMH-38™ AND AMH-100™ OPERATION AND MAINTENANCE MANUAL OPERATION Once the AMH mass set has been installed (see Section 2.6) and the AMH mass handling system has been initialized (see Section 2.7) and installed, regular operation of the AMH is controlled by the P7000 Platform in response to local commands entered on the PG Terminal or remote commands received over the PG7000 Platform’s COM1 or IEEE-488 interface.

    AMH feet enter the holes in the PG7000 Platform. Assure that all three feet fully enter and seat in the platform holes. Tighten the platform set screws using a 2.5 mm allen wrench provided in the AMH-100 accessories, one for each of the feet.

  • Page 33: Removing The Amh Mass Handler From The Pg7000 Platform

    NOTE THAT SHAFT HAS A LEFT HAND THREAD SO IT MUST BE ROTATED COUNTER-CLOCKWISE TO TIGHTEN IT. Use the 3 mm allen wrench supplied in the AMH-100 accessories to tighten the assembly until you feel the masses begin to rotate.

    Lift the AMH-100 off of the PG7000 Platform: Grasping the AMH-100 by the horizontal platform in its middle, lift the AMH-100 straight up until it clears the masses and set it on a flat surface. The AMH-100 mass handler weighs about 12 kg (25 lb.).
