Hazardous Area Oxymitter 4000

Instruction Manual

IB-106-340C Rev. 4.1 July 2004

f.Once the cell is up to operating tempera- ture, the O2 percentage can be read:

1.To access TP5 and TP6 under the LOI module (Figure 4-2), power down the Oxymitter 4000 and remove the LOI module. Attach alligator leads from a multimeter across TP5 and TP6 (Figure 3-2). Install the LOI module and power up the Oxymitter 4000. Allow time for the cell to reach operating temperature. The calibration and proc-

ess gases can now be monitored. When a calibration has been initiated, the value at TP5 and TP6 is the % O2 seen by the cell. Oxygen levels, as seen on the multimeter, are:

8.0% O2 = 8.0 VDC

0.4% O2 = 0.4 VDC
