From the working display press & hold the BH TEST/MENU
BUTTON (B) until the top line reads USER MENU. Press &
release the SAVE/ZERO BUTTON (C) once. The bottom line will
read CALIBRATION.

Press & release the BH TEST/MENU BUTTON (B) once. The
bottom line will read CO/100 PPM. Press & release the SAVE/
ZERO BUTTON (C) once. The bottom line will read H2S 25ppm.
Apply 25ppm H2S/AIR to the instrument and press  & release
the BH TEST/MENU BUTTON (B) to start H2S calibration.

When the reading is satisfactory, the display will flash DATA
SAVED indicating that calibration is complete for that sensor.
The date for  CAL PAST DUE  is automatically reset for that

NOTE: Using calibration kits other than recommended by
SENSIT TECHNOLOGIES  may cause inaccurate readings.
Repairs are required if any sensor fails to calibrate. Con-
sult SENSIT TECHNOLOGIES for details.

NOTE: When calibrating, the numbers shown on the dis-
play represent the numbers seen by the microprocessor
and should not be confused with actual gas readings.
These readings will update every 5 seconds during cali-
bration.

The following instructions pertain to manual calibration of the
Sensit Gold CGI. If you are using the automatic Smart-Cal Cali-
bration System, the procedure is different. See the Smart-Cal
sections of this manual (page 35) or consult the Smart-Cal in-
struction manual for details.

From the working display press & hold the BH TEST/MENU
BUTTON (B) until the top line reads USER MENU.

Press & release the SAVE/ZERO BUTTON (C) once. The bot-
tom line will read CALIBRATION.

Press & release the BH TEST/MENU BUTTON (B) once. The
bottom line will read CO 100ppm. Apply 100ppm CO/Air calibra-
tion gas and press & release the BH TEST/MENU BUTTON (B)
to start CO calibration.
