OPERATION
After the 921A has been configured, it is ready for operation. Turn on the
921A and allow it to perform its self-test routine and enter the Calibration
Mode.
The operator's display contains two lines of information. The first line
provides data about the device test configuration, i.e., the device part
number, the version of the device configuration, and the work order (if
applicable). This information is dependent upon the device test parameters
stored in memory for the configuration. The second line of the display
provides instructions for the operator.
Note: A valid configuration must be previously installed using the PC DFR
Operations Software. If not, refer to the DFR Operations Software
Manual and create/install a configuration in the 921A prior to
proceeding.
4.1 CALIBRATION MODE
The Calibration Mode is used to obtain measurement references and is
automatically entered upon the successful completion of a self-test routine. It
can also be entered by pressing the MODE switch on the front panel
whenever the operator's display indicates READY. The 921A will also enter
the Calibration Mode if the Configuration is changed and the new device
configuration requires a different calibration. Whenever the 921A is in
Calibration Mode, only the CAL indicator is illuminated.
Press the Mode (CAL) switch to enter the Calibration Mode.
If the configuration parameters include a Reference Block Size (Ref Blk Size)
value other than zero (refer to the DFR Operations Software Manual for
details) the display will prompt for installation of the Distance Reference
Gauge at this point; then to press test. (See restrictions, Appendix A).
If the Ref Blk Size value is zero or not applicable in the configuration, then
the message Ensure Pedestal Setup for CAL is displayed. Press TEST
when ready.
