Bump Testing the Gas Tracer
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.
From Measuring Mode, enter Calibration Mode by pressing and
holding the (SHIFT)▼ button, then pressing the DISPLAY(ADJ)
button and releasing both. If the unit prompts you for the password,
enter it by using the AIR▲ and (SHIFT)▼ buttons to select each
password number and then pressing and releasing POWER ENTER to
confirm it and move on to the next number. To go back a number, press
and release the RESET SILENCE button.
The factory set password is the
same as the factory set password for Maintenance Mode: 2102. You
can change the password by entering the PASSWORD menu item in
Maintenance Mode. See “Turning the Password Function On or Off”
on page 172. If you enter an incorrect password, an error screen will
display.
