5. When sensor zero is complete, remove the nitrogen
and press  [OK] or  [Cancel] to exit
calibration.
The Meter displays:
Apply CO Calgas concentration…
6. Enter the concentration amount using  [DOWN]
and  [UP] to change the entry and 
[ENTER] to store it.
7. Apply the calibration gas mixture of CO and CO

.
Press  [OK] or  [Cancel] to exit calibration.
8. When finished, remove gas and press  [OK].
Enter the time to next calibration date. Use 
[DOWN] and  [UP] to change the number and
 [ENTER] to store the number.
The calibration procedure is complete.
Calibrating the CO Sensor
To calibrate the CO sensor:
1. With the calibration cap on, press , , and
 simultaneously for 3 seconds to enter
calibration mode.
2. Press  [Yes] to initiate the calibration procedure
or press  [Cancel] to exit calibration mode.
3. Press  [CO]. The Meter zeros the CO sensor. If
desired, press  [Cancel] to abort Meter
calibration.
4. Use  [DOWN] and  [UP] to change the gas
concentration (ppm). Press  [ENTER] to enter
the concentration level.
5. The Meter prompts to apply the CAL Gas. Attach the
mixed CO and CO
2
calibration gas canister to the
Meter via the supplied hose or press  [SKIP] to
exit.
6. The Meter calibrates the CO sensor. Press  to
cancel. When finished, remove gas and press 
[OK]. Enter the time to next calibration date. Use
 [DOWN] and  [UP] to change the number
and  [ENTER] to store the number.
Note
When either CO or CO
2
sensors are calibrated,
the calibration date is reset by the user.
CO calibration is now complete and the Meter exits
calibration mode.
Calibrating the CO
2
Sensor
To calibrate the CO
2
sensor:
1. If not already in calibration mode, with the calibration
cap on, press , , and  simultaneously
for 3 seconds to enter calibration mode.
2. Press  [Yes] to initiate the calibration procedure
