The fixed position of the crystal being measured also makes it unnecessary to change the tooling factor. RSH-600 can be used to deposit a different material on each of six crystals providing greater measurement accuracy. Upon completion of deposition of one material, the deposition controller may be programmed to switch crystals for the next material.

RSH-600 Operating Manual 2.1 Configurations RSH-600 can be configured with a flat head or a 45° angled head. This allows for mounting in various locations within the vacuum chamber. Standard head covers are made of stainless steel. Copper head covers are available for applications where...
RSH-600 Operating Manual 2.2 Functional Verification RSH-600 is equipped to operate on a 115 V (ac), 60 Hz line or a 24 V (dc) supply, depending on the model number. The required voltage on the body of the pneumatic valve mounted on the side of RSH-600 can be verified. RSH-600 may be bench checked using the following procedure: Connect air pressure (55 psi) via 6.35 mm (1/4 in.) plastic tubing to the air inlet...
RSH-600 Operating Manual 2.3 Crystal Sensor Installation Install the sensor as far as possible from the evaporation source (a minimum of 30.5 cm (12 in.)) while still being in a position to accumulate thickness at a rate proportional to accumulation on the substrate.
The RSH-600 smooth sealing surface mounts to an O-ring sealed nipple (not included). The optional adjustable flange allows the in-vacuum length to be adjustable up to the RSH-600 original length. A flat head cover is typically used for centered top mount applications while the angled heads may be used for either off-center top mount or side mount applications.
O-ring groove in the adjustable flange. Loosen the hex socket head screw on the adjustable flange. Remove the cover from the RSH-600 sensor. If the crystal holder contains any crystals, remove the holder and remove and discard the crystals. Reinstall the crystal holder.

RSH-600 Operating Manual Stand the RSH-600 sensor upright on a firm surface. Place the adjustable flange, with smooth side up, over the top of the sensor barrel. With the flange seating surface perpendicular to the sensor barrel, forcefully push the flange downward, sliding the flange onto the sensor barrel.
Note the position of this spring and replace the crystal retainer. Carefully slide the cover over the barrel of RSH-600 until it touches the crystal retainer, then rotate the cover so that the crystal, in contact with the spring, is centered in the hole in the cover.

The crystal requires sufficient water cooling to sustain proper operational and temperature stability. Ideally, a constant heat load is balanced by a constant flow of water at a constant temperature. INFICON quartz crystals are designed to provide the best possible stability under normal operating conditions. No crystal can completely eliminate the effects of varying heat loads.
Loosen the three Allen head screws that attach the head cover to the copper clamping ring. (Leave clamping ring attached). Carefully slide the head off of the barrel of the RSH-600 sensor. Loosen center screw of the head to release crystal retainer.
