Calibration

4. Calibration

4.1 New Probe

New Probe Reset Option

Upon system power up or probe connection, the new probe reset option is
displayed. The

nPrb

message is available for 2 minutes and can be selected by

pressing the up arrow until the display changes to the unit type and DO value. The
Air and Sample calibration values are set to the factory defaults and the probe
current is measured and saved as a diagnostic aid. An Air calibration is
recommended after a new probe is installed.

If a new probe is not installed, the operator can return to on-line measurement by
waiting for the 2 minute timeout or by pressing the Mode button.

4.2 Calibration Options

Introduction

Whether the probe is connected for the first time, replaced or just disconnected and
then reconnected, a reconditioning period is needed before the probe can make an
accurate measurement. (See DL5000 Probe Manual 70-82-25-114)

Options

Two Calibration options are available: Air and Sample Calibration.

These parameters can only be selected when online DO is displayed.



Air Calibration

- is done with the probe removed from the process. This is the

recommended method of calibration and should be completed unless the
process set-up prohibits removing the probe. This is recommended prior to
installation as it saves system parameters that are used in optimizing error
diagnostics.

If the probe has just been removed from a sample low in dissolved oxygen, it
takes longer to complete a calibration than that of a probe that is already near
ambient conditions (sample high in dissolved oxygen).



Sample Calibration

- Sample calibration allows a calibration based on a known

dissolved oxygen concentration where a DO value may be entered that is based
on a reference measurement. Sample calibration is usually executed by leaving
the probe in the measured sample and adjusting the DirectLine® to agree with
the sample dissolved oxygen measured with a properly calibrated portable
dissolved oxygen meter whose probe is held very close to the process probe.

For those situations where sample calibration is preferred, it is recommended
that an Air Calibration be performed before the probe is put into service. It is also
good practice to Air Calibrate the probe once every 2 - 4 months of service.
