Installation
Each Compact 2A is designed to be used in conjunction with a 2A Thermocouple sensor. The 2A
sensor can be mounted in any orientation. The sensor should be mounted close to the area where
vacuum measurement is desired. Each 2A sensor has a key that only allows the sensor end of the
Compact 2A cable to mate with the sensor in the proper orientation. Rotate the sensor end of the
Compact 2A cable until the correct alignment is obtained and the Compact 2A cable is able to slide
onto the 2A sensor. Connect the RJ14 end of the Compact 2A cable into the port on the back of the
Compact 2A. It is recommended that the ground connector on the cable is also connected to the port
on the back of the Compact 2A labeled with the universal earth ground symbol.
Try to avoid connecting the 2A sensor to the vacuum chamber by long or narrow piping as this may
affect the accuracy and response time of the unit. Avoid mounting the unit near a heater within the
chamber as this may affect the measurement accuracy. Excessive vibration of the sensor may affect
accuracy and decrease the life of the sensor. Exposure to oils and other contaminants will decrease
the accuracy and decrease the life of the sensor. Do not expose the sensor to corrosive gases.
