CALIBRATION
(MANUAL CALIBRATION)
STANDARD FEATURE
The calibration menu in the
SENSIT GOLD G3
contains the options for both the (manual) Auto
Calibation feature and manual individual sensor calibrations. It does not contain the option for
Smart-Cal, if you are calibrating the instrument using a
SMART-CAL 360
calibration station.
For information on Smart-Cal, see the section in this manual, or the instruction manual for the
station.
The following instructions show how to perform manual calibrations of individual sensors in the
SENSIT
®
G3
. If you are using the automatic
SMART-CAL 360
Calibration Station, or the
AUTO CALIBRATION option, the procedure is different.
Calibration is the process of setting the readings of the instrument to equal the value of certified
calibration gases. Prior to calibration allow the instrument to operate for 5 to 10 minutes in a
room environment free of combustible, CO, H2S or HCN gases.
Currently, the AUTO CALIBRATION feature is not supported.
TO MANUALLY CALIBRATE METHANE TC & LEL 2�5 %VOL OR 2�2%VOL
NOTE:
The methane 2.5%VOL or 2.2%VOL calibration point has two different options in the
calibration menu, for both sensors that are calibrated to that gas (LEL and TC). Both calibrations
should always be done, and never one without the other.
1. From the working display, press and hold the
B
button until USER MENU is shown near
the top of the display.
2. Press and release the
C
button until CALIBRATION is shown.
3. Press and release the
B
button to enter the CALIBRATION menu.
4. Press and release the
C
button until METHANE TC 2.5 VOL or 2.2%VOL is shown.
5. Attach 2.5%VOL or 2.2%VOL methane calibration gas to the end of the gooseneck. Ensure
gas is flowing.
6. Press and release the
B
button to start the calibration.
7. Wait for either a PASSED or FAILED result to be shown.
a. If PASSED is shown, the calibration was successful, and the calibration due date will be
automatically reset for that sensor. Leave the calibration gas attached and continue with
these instructions to calibrate the LEL sensor.
b. If FAILED is shown, leave the calibration gas attached and attempt calibration again.
If successful calibration cannot be achieved, remove the instrument from service and
contact the factory for assistance.
8. METHANE LEL 2.5 VOL or 2.2%VOL will be shown. Press and release the
B
button to start
the calibration.
9. Wait for either a PASSED or FAILED result to be shown.
