3.4.3 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 also “Sensor Calibration” on page 36).

You should also consider the changes in required flow rates and response times, which are listed in “Sensor Specifications” on page 56.

To re-configure the analyzer, choose Configuration, Membrane to bring up the box which reveals the membrane models available.

Membrane 29561A is available for any gas measurement. Membranes 2935A and 2952A are available for H2 measurement only.

Choose OK when the desired membrane is selected.

Note:

Only those membranes applicable to your system can be selected. All other membranes are grayed out.

3.4.4 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 WIN3654 program's Configuration, Sampling Rate menu lets you select time intervals (acquisition rate) for this storage capability.

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 WIN3654 program for data acquisition, as described in “Automatic Data Acquisition” on page 20.

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 25. 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.
