Mounting the Circal Fig.1: The Circal disc Fig.2: After mounting Fig.3: Note the notch Get the Circal disc and put it into the hole of the Circal. Then screw it on by turning the white wheel of the Circal disc. Note the notch (Fig.3) which determines the mounting position. Please do not fix the Circal too tightly. Just a notch beyond smooth turning of the Circal will suffice. B. Mounting the sensors Fig.

The first magazine holds sensor 1 to sensor 4, counted from right to left. The second magazine holds sensors 5 to 8, and the third magazine holds sensors 9 to 12.

AG501 cs5cal (PD-02.05) Page 4 of 11 D. Starting cs5cal 1. Enter the name of the calibration set You will be asked for the name of the calibration set. A folder with this name will be created (/data/calibration/). This folder becomes the calibration set. It will also contain a file with this name and the extension ".calset". Enter a unique name. According to the common rules for file names, it must not contain any special characters. Thus, *#&$~\[]()`<>|,.^". and spaces are not allowed. Fig.

Location of the calibration data calibration sets Fig.11: The calibration folders The complete data from each calibration is stored in one subfolder of the "calibration" folder. Fig.12: contents of a calibration set Fig.13: links on desktop Additionally there is a subfolder TMP *.tmp that holds intermediate results.

Step 1 Step 4 Step 2 Step 5 Step 3 Wait until this window appears 5. Calibration has finished In case of defective or missing sensors in a calibration, the concluding dialog informs about how many sensors were calibrated successfully, and for which sensors and why calibration failed (Fig. 15). Fig.

AG501 cs5cal (PD-02.05) Page 8 of 11 After closing the dialog you can find an overview of the calibration results in the cs5cal-window. Information on defective sensors is attached at the bottom of the calibration results (Fig. 16). The information is stored in the calibration protocol (see Check the calibration result II.D.7). Calibration results Defective sensors Fig.16: Calibration protocol with results and information on defective sensors 6.

Check the calibration result The important information that is needed in order to review the calibration results is in the calibration protocol file (*.txt) inside the calibration set sub folder. a) An Example calibration protocol file: To get a better overview, the data of channels 2 to 15 is omitted. Calibration protocol Given name is: test-1 Moving circal .. Circal ready. Creating calset: /data/calibration/test-1.calset Circal ready. Moving circal ..

AG501 cs5cal (PD-02.05) Page 10 of 11 E. Trouble shooting While moving the initial circle of the calibration the software checks for low amplitudes and errors in the sensor sequence. The calibration process is halted if errors are detected. 1. Low amplitudes Low amplitudes indicate broken sensors or a bad sensor connection. Please check sensors and sensor connections. If the error persists even after sensor replacement, the affected channels have to be tested for hardware errors. 2.
