User interaction is accomplished via remote communication and consists of the selection or entry of parameters to define the material and instrument characteristics. A complete QCM system consists of an electronics unit, also called IMM-200, a power supply, a sensor head containing a quartz crystal and software to communicate to IMM-200.

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.
RMA number, the package will be held and the sender will be contacted. This will result in delays in servicing IMM-200. Prior to being given an RMA number, a Declaration Of Contamination (DOC) form may need to be completed if the product has been exposed to process materials.

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.
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.
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.

For most applications the following three rules provide reasonable accuracies: 1. If the thickness of material 1 is large compared to material 2, use material 1 Z- Ratio value for both materials. 074-733-P1A IMM-200 Operating Manual 39 / 67...
