Calibrating Instruments
The Data Cal 2000 is capable of performing a calibration both manually
and automatically on an instrument connected to it. When a calibration is
performed, the Data Cal 2000 performs an air adjust operation on an
instrument and then applies calibration gas to the instrument. The Data
Cal 2000 analyzes the calibration results and determines if the
instrument passed the calibration.
To perform a manual calibration on an instrument that is connected to the
software:
1. Verify that the appropriate calibration gas cylinder or cylinders are
connected to the appropriate fitting or fittings on the back panel of
the Data Cal 2000. See “Setting Up the Solenoids” on page 36.
2. From the main program window, select the instrument you want to
calibrate by clicking on it in the docking module/instrument window.
To select additional instruments, hold down the Shift key while
clicking each additional instrument. All selected instruments will be
calibrated.
3. Click the Calibration button. The Data Cal 2000 will initiate a
calibration. During the calibration, the Data Cal 2000 will perform
the following functions:
• It will apply fresh air to the instrument for 45 seconds.
• It will perform a zero operation on the instrument.
• It will apply the necessary calibration gas to the unit for 90
seconds. If more than one cylinder is required for a calibration,
such as a %volume CH4 cylinder and a 4-gas mix cylinder for a
5 sensor GX-2003, then gas from each cylinder will be applied
for 90 seconds each.
• After each gas application, a calibration operation will be
performed on the instrument that is appropriate for that cylinder.
