Mode 1 Calibration (Continued)
1. Press the AutoCalibrate button. You will see the Begin AutoCalibrate dialog box.
2. Ensure the correct coils are connected to the H and B Input Sensing Coil connectors on the electronic
console rack mount panel and the probe is connected to the Model 450 Gaussmeter.
3. Click the OK button. The software begins the sensor identification process which begins the Autocalibrate
routine. If successful, you will see the Choose Setup File dialog box.
NOTE: If the software is unable to find a probe/setup file match, an error message will be displayed. The user
must then determine manually the appropriate setup file to use manually without the aid of setup
/sensor ID matching. Press ‘Retry’ to display all setup files stored in the computer, or press ‘Cancel’ to
terminate the Autocalibrate process and return to the main screen.
4. The Serial Numbers and Date Code for the B and H Fluxmeter are displayed in their respective blue fields.
These numbers are read from the EEPROMs in the connector shell of the respective sensor. This value is
compared with the setup files to determine the list of appropriate setup files for the attached sensors.
5. If the sensors attached to the system have changed, select either the Re-Initialize B or H Fluxmeter’s
Auto Drift Adjust button, as appropriate. This button will cause the respective fluxmeter to go into auto-
drift adjust mode for 25 seconds. Auto-drift adjust matches the parameters of the coil with those of the
fluxmeter integrator.
6. In the “Setup Files” window, select a setup file (*.SET) that is compatible with the attached sensing coils.
7. Press the Accept button. If an acceptable Setup file is selected, the Gaussmeter dialog box is displayed.
