1. Program description:
3
 
4
This is a program for monitoring the fieldpoint temperature sensor (National Instruments FP RTD-122) in the F9 photon detectors laboratory. As an output, it produces a formatted text output and an optional ROOT plot. Note that this program will only work on computers connected to the IJS network (IP = 178.172.43.*).

2. Installation instructions:
8
 
9
Make sure environmental variables for ROOT are set and that there is an installation of ROOT with MySQL support on the running computer (./configure --enable-mysql).

11
Installation is done by using
12
> make
13
 
14
Run the program with
15
> ./start.sh
16
 
17
Clean the installation by using
18
> make clean

3. Program use:
22
 
23
Program use is straight-forward:
24
- Fieldpoint channel selects the channel we wish to get temperature from.
25
- Start and end time determine the data range to be retrieved from the MySQL database.
26
- Draw to last time point selects the data range between start time and the most current point in the database.
27
- Output data settings determine what kind of format should be used for timestamps in the text output (local time, UNIX timestamp).
28
- Update button updates the plot, Export button exports the plot (saved in folder ./fieldpoint) and Close button closes the application.
29
- At any change in start or end times and updating the plot, the text output (saved in folder ./fieldpoint) is also updated.

4. Time difference - Important!
33
 
34
Data saved in the MySQL database have a time shift to the current local time. To fix this time shift use the ./time_offset script (password needed to connect to f9lab04), followed by the installation instructions above (make). The timing of old datapoints can still be wrong!
