Teledyne API – Model T700 Dynamic Dilution Calibrator Overview of Operating Modes and Basic Operation
97
Table 4-1: Calibrator Operating Modes
MODE DESCRIPTION
STANDBY
The calibrator and all of its subsystems are inactive.
GENERATE In this mode, the instrument is engaged in producing calibration gas
mixtures.
MANUAL In this mode, the instrument is engaged in producing calibration
gas mixtures.
PURGE The calibrator is using diluent (zero air) to purge its internal
pneumatics of all source gas and previously created calibration
mixtures.
GPT
1
The calibrator is using the O
3
generator and source gas inputs to
mix and generate calibration gas using the gas phase titration
method.
GPTPS
2
Stands for Gas Phase Titration Preset. In this mode the T700
determines the precise performance characteristics of the O
3
generator at the target values for an upcoming GPT calibration.
SETUP
3
SETUP mode is being used to configure the calibrator.
DIAG One of the calibrator’s diagnostic modes is being utilized. When
the diagnostic functions that have the greatest potential to
conflict with generating concentrations are active, the instrument
is automatically placed into standby mode.
1
This mode is not available in units without O
3
generators installed.
2
This mode is not available in units without internal photometers installed.
