12.Disconnect the tubing from the Gas Tracer’s probe.
13.Repeat steps 7 through 12 for any other sensors you want to
calibrate. Make sure you use an appropriate calibration cylinder for
each sensor.
CAUTION: When calibrating the oxygen channel, verify the concentration
of oxygen listed on the cylinder’s label. For oxygen-free samples
(100% nitrogen for example), set the oxygen zero setting to
0.0%.
14.After the last channel is calibrated, disconnect the calibration
tubing from the probe, then unscrew the demand flow regulator
from the calibration cylinder.
15.Use the AIR▲ and (SHIFT)▼ buttons to scroll to ESCAPE in the
ONE CAL menu.
16.With the ONE CAL menu option displayed, press the (SHIFT)▼
button until the NORMAL menu option is displayed.
17.Press and release the POWER ENTER button to return to
Measuring Mode.
Performing a Bump Test
NOTE: The BUMP DSP menu item in Maintenance Mode is factory
set to OFF. The BUMP menu item will not appear unless
BUMP DSP
is set to ON. See “Turning the Bump Test
Function On or Off” on page 157 for instructions.
NOTE: The Gas Tracer uses parameters defined in the BUMP--SET
menu item of Maintenance Mode while performing a bump
test. To view or update these parameters, see “Updating the
Bump Test Parameters” on page 158.
NOTE: If the combustible gas channels are calibrated to a gas other
than methane, use an appropriate multigas cylinder.
If the BP RMNDR menu item in Maintenance Mode is set to ON (see
“Updating the Bump Test Reminder Setting” on page 165), and the BP
EXPRD
menu item in Maintenance Mode is set to NOT USE (see
“Updating the Bump Test Expired Action Setting” on page 165) and a
bump test becomes due, then the standard 3 sensors must be bump
tested using this menu item because it will not be possible to enter
normal operation. See “Calibration/Bump Test Supplies and
Equipment” on page 62 for the items you will need to perform a
