Calibrating the Gas Tracer
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.
NOTE:
The following screens illustrate a three-gas Gas Tracer with a %LEL and
a %volume combustible sensor as examples only. Your Gas Tracer may
display slightly different screens.
The Gas Tracer’s calibration menu includes two methods of calibration:
• Auto Calibration: This method allows you to calibrate the combustible gas
(%LEL sensor only), OXY, and CO sensors simultaneously. It is designed for
use with the RKI 3-gas calibration cylinder and is the quickest and easiest
method to calibrate the Gas Tracer. If installed, you may also calibrate the
%volume sensor separately from the standard three.
• Single Calibration: This method allows you to calibrate one sensor at a time.
Use this method if you are only calibrating one or two sensors, if you are
calibrating only the %volume combustible sensor, or if you are not using the
RKI 3-gas calibration cylinder.
