Description

Pressure Compensation CH

Monitors and corrects for pressure fluctuations in the sample (if you have
your own pressure transducer). You can use the pressure transducer
separately, or interface it with the sensor system.

If interfacing to the sensor system, you must have an available
spectrometer channel that is NOT connected to an oxygen sensor or
have the OMEGA D5251 4-20mA general purpose module. Specify the
pressure-monitoring method with the drop-down menu.

If an unused spectrometer channel is used as an analog-to-digital
converter (A/D) for your pressure transducer, typically Slave1 to Slave7,
activate it and assign that spectrometer channel as a pressure channel
and enter its calibration coefficients there. If a D5251 module is used,
select the serial COM port used and enter its calibration coefficients.

Additionally, you can enter the pressure manually.

The Pressure applies to all channels which activated manual pressure
compensation and is displayed in the upper left corner of the OOISensors
screen as follows:

Enable reference correction

CAUTION:

This option is

not recommended. Speak
to an Ocean Optics
Application Scientist
before setting.

Monitors and corrects for any drift or change in the LS-450 Blue LED light
source. Click to enable this function, and then enter the reference
wavelength in the nm box.

To use this option correctly, be sure the peak at 470 nm is not saturated.

Bandwidth Pixels

Only available if “Enable reference correction” is enabled. Specifies the
number of pixels around the reference wavelength to average.

Level alarm

Configures alarm properties. Click this box to enable the alarm feature,
and then enter alarm-monitoring parameters. When the value is within the
specified value range, the alarm indicator is green. If the value falls below
the specified alarm parameters, the on-screen indicator will turn red. If the
value rises above the specified alarm parameters, the indicator turns
yellow.
