Calibrating and Bump Testing the PPM
Combustible Sensor
The PPM sensor in the Gas Tracer needs to be calibrated and bump tested
separately. It cannot be calibrated using the AUTO CAL or ONE CAL menu items
in the main menu or bump tested using the BUMP menu item in the main menu.
The PPM CAL menu item must be used. In addition, a 6 inch humidifier tube
must be used to connect the ppm calibration cylinder to the instrument.
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 156. If you enter an incorrect password, an
error screen will display.
To return to normal operation, press and release the RESET SILENCE button. You
may then try to reenter Calibration Mode.
MAINTENANCE will appear along the top of the screen once you have entered
Calibration Mode. The first item in the calibration menu, AIR CAL, displays.
