ORBISPHERE
3.4 Configuring the Instrument
The ORBISPHERE 3650 analyzer can be readily configured for your application using
the following commands in the Configuration menu. The instrument must be connected
to your PC in order to change its configuration.
3.4.1 Automatic Data Acquisition - Setting Sampling Intervals
The analyzer can perform as a standalone data acquisition device, automatically
recording gas measurements with the date and time, and storing up to 500 of these
values. Choosing the WinLog97 program's Configuration, Sampling Rate menu lets
you select time intervals (acquisition rate) for this storage capability.
Note:
The Acquisition rate set via this menu is independent from the monitoring chart updating
rate described in “Monitoring Measurements In Real-Time” on page 21. The sampling
rate menu applies only to automatic data acquisition, while the chart updating rate is
used only for displaying real-time results via the monitoring chart.
3.4.2 Membrane Selection
You may find it necessary to use a different type of membrane for different applications.
Naturally, with any membrane change, you will need to re-calibrate (see “Sensor
Calibration” on page 32). You should also consider the changes in required flow rates
and response times, which are specified in the accompanying EC Sensors -
Maintenance & Installation Manual.
Note:
Only those membranes applicable for your instrument model can be selected. All other
membranes are grayed out.
Use the slide bar to view and select a sampling rate, from
15 seconds to 1 hour. The selected rate is shown in the
Acquisition rate window.
Click OK to save this rate. Once your choice is made, the
analyzer can be used independently of the WinLog97
program for data acquisition, as described in “Automatic
Data Acquisition” on page 16.
