2.Verify the calibration gas parameters are correct per "Calibration with Keypad".

3.If performing a manual calibration with the CALIBRATION RECOMMENDED LED off and the CAL LED off, start at step a.

4.If performing a manual calibration with the CALIBRATION RECOMMENDED LED on and the CAL LED on, start at step b.

a.Push the CAL key. The CALIBRATION RECOMMENDED LED will come on and the CAL LED will be on solid. If a multimeter is attached across TP5 and TP6, the reading will display the percentage of oxygen seen by the cell.

b.Push the CAL key. The CALIBRATION RECOMMENDED LED will turn off and the CAL LED will flash continuously. The Oxymitter 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 Oxymitter 4000 is ready to accept the first calibration gas.

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

d.Push the CAL key; the CAL LED will be on solid. A timer is activated to allow the calibration gas adequate time to flow (default time of five minutes). When the timer times out, the Oxymitter 4000 has taken the readings using the first calibration gas and the CAL LED will flash continuously. The flashing indicates the Oxymitter 4000 is ready to take readings using the second calibration gas.
