Emerson Process Management IM-106-340 Purge xxxxs, Abort Calibration, Previous Calibration

Oxymitter 4000

Instruction Manual

IM-106-340, Rev. 4.0 May 2006

The display counts down the seconds remaining to flow Gas 1, then the time remaining for sensing the O2 concentration of Gas 1. Done Gas 1 indicates completion.

3.Remove the first calibration gas and apply the second calibration gas. (Electronics will abort the calibration if this step is not done within 30 minutes). The LOI displays the following:

Apply Gas 2

Hit E when ready

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

Flow Gas 2 xxxxs

Read Gas 2 xxxxs

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:

Purge xxxxs

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

Abort Calibration

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

Cal Constants - Results of the Calibration

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.

Previous Calibration

Values from the prior good calibration.

Failed Calibration

Bad calibration values are not loaded into the electronics.

Calibration Status

Calibration Step

The current step in an active calibration procedure.

Calibration Time

Time until the next scheduled calibration.

Next O2 Cal

Time until the next O2 calibration, if different than the next scheduled calibration.
