AUTO CAL automatically calibrates the instrument to all gases

detected by the sensors installed. From the AUTO CAL menu,

press the TICK/MENU BUTTON (B) . Attach the prepared gas

as listed on the display. A countdown timer shows the time re-

maining to connect . Failure to connect will result in a FAIL

message and an alarm sound (press any button to continue).

During the test, the gas type, the target concentration and digi-

tal output of the sensor (not concentration) will be displayed.

Following each gas tested PASS or FAILED will be displayed. It

is possible to manually stop the test once it is started by press-

ing the POWER/MUTE BUTTON (A).

At the end of the test BUMP TEST (PASS or FAILED) will be

indicated. Pressing the POWER/MUTE BUTTON (A) will save

the results and return to the USER MENU.

Pressing the SAVE/ZERO BUTTON (C) will scroll through the

individual sensors that are configured in your G2 for calibration.

Pressing the TICK/MENU BUTTON (B) selects the option. At-

tach the proper gas and wait for the instrument to provide a

PASS or FAILED indication.

If the calibration has failed press the POWER/MUTE BUTTON

(A) to attempt again or scroll to the next gas. Upon successful

calibration the calibration due date reminder is automatically

updated.

From this menu pressing the SAVE/ZERO BUTTON (C) again

will provide access to the SMART-CAL automatic calibration

system. Pressing the TICK/MENU BUTTON (B) from SMART-

CAL menu begins the communication process. Consult the

SMART-CAL system instructions for connection details.

ment that does not accept calibration should be taken out

of service. Please contact SENSIT TECHNOLOGIES for any
