3. Click the Bump test button. The Data Cal 2000 will initiate a bump
test. During the bump test, 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 the
number of seconds defined in the Gas Exposure Time setting in
the Parameter Tab of the Configuration Window (see
instruction 9 on page 30). If more than one cylinder is required
for a bump test, such as a %volume CH4 cylinder and a 4-gas
mix cylinder for a 5 sensor GX-2003, then gas from each
cylinder will by applied separately for the required amount of
time.
4. When the bump test is completed, the software will analyze the
results and display the Calibration & Bump test Result window
which shows the bump test results. If the instrument or instruments
passed the bump test then the following indication is given.
