Ocean Optics OOISensors - Manual (Page 25)

2: OOISensors Software
Option Name Description
Temperature Measurement
Specifies the method used to monitor and correct for temperature
fluctuations, if desired:
None: No monitoring
Manual: Temperature is monitored, but OOISensors will not read and
display temperature values. You must manually enter temperature values
in the display window.
Select Omega D5xx1 RS232 monitor temperature and have OOISensors
automatically read and display temperature values
from thermistor or
thermocouple.
Ocean Optics offers the Omega Thermistor and the Omega
Thermocouple for monitoring temperature. The thermistor and
thermocouple should already be connected to your PC via an RS-232
module. Select the COM Port number (next to Serial Port) on your PC to
which the thermistor or thermocouple is connected. Because the RS-232
module can support up to four thermistors or thermocouples, there are
four labeled ports. Next to D5xx1 CH, select the port to which the
thermistor or thermocouple connects to the RS-232 module. (If you only
have one thermistor or thermocouple, select 0.)
Select USB2000 LS-450 to instruct the USB-LS-450 to monitor and
correct for temperature fluctuations. The A/D converter in the USB-LS-
450 front end is configured for a 100 ohm platinum RTD (resistance
temperature device).
A similar method is used with the OMEGA D5251 general purpose 4-
20mA module, which requires your own temperature sensor with current
output. You must calibrate the input and create its calibration coefficients.
Enable the Compensate function if you want the software to correct for
temperature fluctuations. Enabling the Chart function allows you to view
a chart of the temperature values.
