2Push the CAL key. The CALI-

BRATION RECOMMENDED LED will turn off and the CAL LED will flash continuously.

The Hazardous Area Oxymit- ter 4000 can be configured so that the 4-20 mA signal will hold the last value. The default condition is for the output to track. A flashing LED indicates that the Hazardous Area Oxymitter 4000 is ready to accept the first calibration gas.

3Apply the first calibration gas. (Electronics will abort the cali- bration if step 4 is not done within 30 minutes).

4Push the CAL key; the CAL LED will be on solid. A timer is activated to allow the calibra- tion gas adequate time to flow (default time of five minutes). When the timer times out, the

Hazardous Area Oxymitter 4000 has taken the readings using the first calibration gas and the CAL LED will flash continuously. The flashing indicates the Hazardous Area Oxymitter 4000 is ready to take readings using the sec- ond calibration gas.

5Remove the first calibration gas and apply the second calibration gas. (Electronics will abort the calibration if step 6 is not done within 30 minutes).

6Push the CAL key; the CAL LED will be on solid. The timer is activated for the second calibration gas flow. When the timer times out, the CAL LED will flash a 2 pattern flash or a 3 pattern flash (2 pattern flash equals a valid calibration, 3 pattern flash equals an invalid
