• Bump Test Past Due Act: The Bump Test Past Due Act determines how the
instrument will react to a needed bump test during the start up sequence. If
Bump Test Past Due Act is set to Confirm to Bump Test (factory setting), the
instrument will sound an alarm and the user will have to press and release the
POWER ENTER button to continue. If set to Must Bump Test, the instrument
cannot be used until a bump test has been performed. If set to Notification Only,
the instrument will display that a bump test is due but will continue with the warm
up sequence. See the GX-2012 Operator’s Manual or Gas Tracer Operator’s
Manual for a description of the start up sequence.
• Bump Check Gas: The Bump Check Gas setting defines which sensors are
used to update the bump test reminder screen. If it is set to 4-GAS (factory
setting), the bump test dates for only the standard 4 sensors (LEL, O
2
, H
2
S, and
CO) are used to determine if calibration is due. If Bump Check Gas is set to ALL,
the bump test date for the standard 4 sensors along with the %volume sensor
and ppm sensor (Gas Tracer only) are used to determine if a bump test is due.
• Bump Test Time(Sec): The Bump Test Time(Sec) setting indicates the amount of
time that the instrument is exposed to gas during a bump test. It can be set to 30
(factory setting), 45, 60, and 90 seconds.
• Calibration After Bump Test Failed: With Calibration After Bump Test Failed
selected (factory setting), if a bump test performed without the SDM-2012 fails,
the unit will automatically begin a calibration. With Calibration After Bump Test
Failed deselected, if a bump test performed without the SDM-2012 fails, nothing
will happen. See the GX-2012 Operator’s Manual or Gas Tracer Operator’s
Manual for a description of bump testing a GX-2012 or Gas Tracer away from
the SDM-2012.
• Bump Test Threshold(%): The Bump Test Threshold(%) setting defines the
percentage that the bump test readings can differ from the actual gas
concentration. If the bump test reading differs more, the bump test will fail. It can
be set to 10, 20, 30 (factory setting), 40, or 50.
• Calibration Time(sec) After Bump Test Failed: This setting defines the amount of
time the instrument will remain exposed to calibration gas after a failed bump
test if the Calibration After Bump Test Failed parameter is selected. The bump
test time is deducted from the calibration time. For example, if Calibration
Time(sec) After Bump Test Failed is set to 90 seconds and Bump Test
Time(Sec) is set to 30 seconds, the instrument will only be exposed to gas for an
additional 60 seconds. The setting can be 90 seconds (factory setting) or 120
seconds.
