CALIBRAnON Background Plateau Background plateaus may now be run for the hand probe board if it is installed and communicating properly. Pressing F5 in the Select Detectors screen toggles the selection of the hand probe detector. If the hand probe option is installed but the board is not communicating, a message will appear in the Select Detectors screen informing the user that the hand probe is not communicating. Pressing F5 when choosing to view plateau data also selects the hand probe detector. Plateau data may be viewed even if the hand probe board has a communication failure. Source Plateau Source plateaus may now be run for the hand probe board if it is installed and communicating properly. Pressing F5 in the Select Detectors screen toggles the selection of the hand probe detector. If the hand probe option is installed but the board is not communicating, a message will appear in the Select Detectors screen informing the user that the hand probe is not communicating. Pressing F5 when choosing to view plateau data also selects the hand probe detector. Plateau data may be viewed even if the hand probe board has a communication failure. Efficiencies The hand probe detector may now be selected for an efficiency test if the hand probe is installed and is communicating properly. As for the plateaus, pressing F5 selects the hand probe detector and starts the test. If the hand probe option is installed but the board is not communicating, a message will appear in the Select Detectors screen informing the user that the hand probe is not communicating. To view the test results, press F5 to select the hand probe detector. Efficiency data may be viewed even if the hand probe board has a communication failure. EDIT Hand Probe Parameters Six new parameters are available for the hand probe. An alarm setpoint may be entered for both the alpha and the beta channels. This setpoint is expressed in the count rate units selected for the <strong>PCM</strong>-2 (CPS or CPM). In addition, a weighting factor and a background sigma factor may be entered for both the alpha and beta channels. These parameters are used in a "smoothing" algorithm which has been incorporated for the hand probe readings to allow the user to control the response time and the step change for the hand probe readings. Ref. No. 2183IMI21831N0vember 1994
OPTIONS Hand Probe Option (<strong>PCM</strong>2 OPTl) If the hand probe is removed from its cradle during background update or after the results of a measurement are posted, the hand probe readings and the new alarm setpoints are displayed on the screen for both alpha and beta channels. If the alarm setpoints are non-zero, the hand probe readings are compared to the alarm setpoints. If either alarm setpoint is exceeded, the units begins to beep and will continue to beep until the probe is replaced in its cradle or the probe reading falls below the alarm setpoint. Setting the alarm setpoint to zero disables the alarm checking for that particular channel. Ref. No. 2183IMI2183INovember 1994
