Teledyne 2002 instruction manual Specifications

board is also available. The Model 2002 instrument accepts an external TTL level "Remote Zero" to zero the instrument when another instrument (e.g. an ion gauge) indicates that the pressure is less than 1x10-5 Torr. The standard analog output is linear per decade directly corresponding to the control unit’s display.

The Model 2002 comes calibrated for nitrogen. Conversion factors for other gases are selectable by the user (see section 3.5). This direct readout display allows for flexibility in user system configurations which operate with various gases.

An optional serial interface board can be installed to provide RS232 or RS485 support. The Model 2002 control unit fits a standard DIN 43700 insert (1/4 DIN) and mounts into a 3.62 in. (92 mm) square hole. The case is constructed of NORYL rated UL-94-V1 (self-extinguishing plastic) and is equipped with mounting brackets that are adjustable up to 3/16” (4.8mm).
