    INFICON 4.2.3 Earth Ground When using the optional power supply, IMM-200 is connected to earth ground through a sealed three-core (three-conductor) power cable, which must be plugged into a socket outlet with a protective earth terminal. If an extension cable is used, it must always have three conductors, including a protective earth terminal.

    There are two required earth ground connections: Ground 1. The earth ground connection on IMM-200 is a threaded stud with a hex nut. Connect a ring terminal to the ground strap, allowing a good connection and easy removal and installation. This connection must be made at installation. For best protection against high frequency noise, the length-to-width ratio of the earth conductor should not exceed a ratio of 5:1.

    This command is very useful when using a rotary sensor head. Since IMM-200 does not control the indexing of the rotary head, it has no way of knowing when a crystal switch is being performed.
  • Page 27: Crystal Type

    6.4 Crystal Type Crystals cut from different crystallographic orientations of quartz can be used with IMM-200. These are referred to as AT, BT, SC, or IT cut crystals. Thickness shear mode waves propagating through these different crystal cuts have different acoustic velocities.
  • Page 28: Crystal Life And Starting Frequency

    Crystal life is reported as a percentage of the monitor crystal’s frequency shift, relative to the 1.50 MHz frequency shift allowed by IMM-200. This quantity is useful as an indicator of when to change the monitor crystal to safeguard against crystal failures during deposition.
