Emerson Process Management OXYMITTER 4000 Purgexxxxs, Abort Calibration, Calibration Status

Instruction Manual

IB-106-340C Rev. 4.1 July 2004

Hazardous Area Oxymitter 4000

4.Touch the Enter arrow to start the Gas 2 flow. The timer is activated and the LOI displays:

Flow Gas 2xxxxs Read Gas 2xxxxs Done Gas 2 Stop Gas

Hit E when ready

5.Remove the second calibration gas and cap off the calibration gas port. Then, touch the Enter arrow to indicate completion. The timer is activated and the LOI displays:

Purgexxxxs

The default purge time is three min- utes. When the gas purge timer times out, the Oxymitter 4000 begins to read the process O2.

b.Abort Calibration

Exits the calibration. After calibration gases are removed, and the purge times out, the instrument goes back to normal operational mode.

c.Cal Constants – Results of the Calibration

1.Current calibration – If the calibration passed these values will be updated. Log these values onto the calibration log sheet supplied. If the process has high levels of particulate, the response back to the process after cal gas is also removed.

2.Previous Calibration – Values from the prior good calibration.

3.Failed Calibration – Bad calibration values are not loaded into the elec- tronics.

d.Calibration Status

1.Calibration Step – The current step in an active calibration procedure.

2.Calibration Time – Time until the next scheduled calibration.

3.Next O2 Cal – Time until the next O2 calibration, if different than the next scheduled calibration.
