- Check the magnet current. If it is not 74.51A, then go to step #2. If the current is 74.51A, then change it to 74A.
- On NMR Terminal, click "NMR Tune".
- Click the box next to the label "Baseline"; and a new window will be opened.
- Click "Create a new Baseline", then this new window will be automatically closed.
- Change the number of sweeps to 5000.
- Then Click "One Point" button, it will take about ~320 seconds for a 5000 sweeps baseline.
- Wait until the indicator (RED) goes to "Pause" after taking the baseline.
- Click "New Baseline" button (to select the baseline that you just took), then it will open a new window).
- Select the Baseline from drop-down list on the left (use the time-stamp to select the correct one), and press the "Selected Highlighted Baseline"; then the window will be closed automatically.
- Change the number of sweeps to 100.
- Click "Take Data".
If you want to create a new "event" file (for example: to take TE measurement), follow the steps on How to create a new event file on PDP
The following section explains the NMR terminal, polarization, and NMR Signal and how to take a new baseline and data.
How do we create a New Baseline?
Click on the Baseline in the above Green circled area, and it will pop up a new window like the one below:
Click on Create a new Baseline. It will close this window and come to the Main Display. After that, follow the picture below to set the sweeps:
Insert 5000 at point 1 (Sweeps) and click at point 2 on 'One Point.' The baseline will be completed in around 324 seconds. You will see a new baseline at the bottom left of the above picture.
