31 • Setting Up the Data Cal 2000 Software
to 90 seconds
• Set the bump test tolerance for each channel. This option for
each channel allows you to set up the criteria for determining if
an instrument passes a bump test. The default value for each
channel for the allowable deviation for a bump test is 30% of the
gas concentration used in the test. These values are adjustable
from 20% to 50%. If the result of the bump test for a channel is
within the set deviation, then the channel passes the bump test.
For example, if the tolerance for the CH4(100%LEL) channel is
set to 30% and 50% LEL CH
4
is used in the bump test, then the
LEL CH
4
channel must respond between 35% LEL and 65%
LEL to pass the bump test.
10. Select the calibration settings in the Calibration section
• Selecting the Manual Calibration selection box activates the
Calibration button in the main window and allows you to
perform a calibration manually.
• If Auto Calibration is selected, the software will automatically
check the last calibration date retrieved from a connected
instrument and compare it to the calibration interval to determine
if a connected instrument is due for calibration and calibrate the
instrument if it is due. For a GX-2003 or a GX-2009, the
calibration interval is saved in the instrument and retrieved by
the Data Cal 2000. You can use the Data Cal 2000 software to
update the calibration interval in the GX-2003 or the GX-2009
(see “Edit Function” on page 74). For a GX-2001, the calibration
interval is defined in the Data Cal 2000 software and can be
updated (see “Edit Function” on page 74). If Auto Calibration is
selected, make sure the appropriate calibration gas cylinders
are always connected to the appropriate fittings on the back of
the docking station when instruments are being connected to the
Data Cal 2000.
