For this test I considered the following 10 channels 1-2-3-4-5 and 17-18-19-20-21.
For each channel I put a load resistance.

In the next image we can see how you have set the Channels:

Then, using the method of the "scan" (Scan Count: 5, Measure Count: 1) I measured the V for the first 5 resistance
and R for the others (See column II(measure) and VII(channels)).
The results are shown in the table below and are saved in a file.

Measure of the value of resistance for all channels (See column II(measure) and VII(channels)):

Next test:
-
Measures with the use of thermometers
- Set the acquisition system to make repeated measurements with the method of the trigger at each time interval.
- Optimization of the save file data.

Test measurements on 10 channels of the multiplexer Empty Test scan every 10 sec (10 channels) for 2 minutes

Setting scan:
- Scan Count: 12
- Measure Count: 1

Setting Simple Trigger:

In this way, every 10s, will start the scan.
All 10 channels are read simultaneously, In this case we measure the value of the 10 resistors:

It could be read simultaneously also their voltage, but will require an additional 10 channels (so the channels will be 20).
In our case, each thermometer will occupy two channels!

Important Points:
-
Must set the Scan Count and Measure Count
-
Must set the Simple Trigger
- Create a save file data
- We can also decide the start time for the scan
- Finally, save the data
