Introduction Model 2750
Teledyne Analytical Instruments 14
1.5 Operator Interface
The front panel contains the operator interface and is readily
accessible after opening the enclosure. It is simple, consisting of an
OFF/ON switch and two rotary switches—one for selecting between
analysis or calibration modes and the other for selecting the particular
analysis range to be employed during measurement. On the same panel
are trim pots used in calibrating the unit.
A large 3.5 digit digital display shows the gas concentration or
calibration information depending on the analyzer mode. A flowmeter
located in the analyzer’s cover monitors the gas flow through the
instrument.
