5 of 8
6. Shift+F2 - Additional Tests, F2 - Optimize Self Shield Factors. [A][S][G][C]
 The names of most recently saves result file is now shown in title row instead of a
message box.
 The “Apply Self Shield” is now shown in title row instead of a message box.
 Pressing F8 = Apply Self Shield to Gamma Zones updates selected Self Shield Type [] on
F3 – Setup, F3 – Detection Zones, F2 – Zone Settings screen which are values used
during measurement. Note that the maximum allowed Self Shied Factor uncertainty on
this screen is ± [5] % (kc=2)
7. Shift+F2 - Additional Tests, Shift+F2 – Anthropometric Correction Fcal Tables. [A][
 Added "F9 = Show Previous Position"
 Added "F10 = Show Next Position"
8. F3 - Setup, F3 - Detection Zones, F2 - Settings. [A][S][G][C]
 Changed Excessive Background Rate [] cps maximum value from [16600] to [100000]
 Changed High Background Rate [] cps maximum value from [16600] to [25000]
 Added Krypton Rate [200] cps to be used instead of High Background Rate [] when
determining if Krypton Self Shield Factor should be applied.
9. F3 - Setup, F3 - Detection Zones, Shift+F3 – Calibration Settings. [A][S][G][C]
 Added Target Uncertainty [] validation that its ≤ 100%
10. F3 - Setup, F3 - Detection Zones, F5 - Group Settings. [A][S][G][C]
 Changed Measurement Process ± [ ] % to Calibration Process ± [ ] %. Pressing
“F7 = Measurement Process ±” applies this to F3 - Setup, F3 - Detection Zones, F3 –
Calibration, detector setting Calibration Process ± [ ] %. Pressing
“Shift+F7 = Measurement Process ±” applies this to F3 - Setup, F3 - Detection Zones,
F3 – Calibration, sum zone setting Calibration Process ± [ ] %
 Added Measurement Process ± [ ] %. Pressing “F7 = Measurement Process ±” applies
this to F3 - Setup, F3 - Detection Zones, F2 – Settings, detector setting
Measurement Process ± [ ] %. Pressing “Shift+F7 = Measurement Process ±” applies
this to F3 - Setup, F3 - Detection Zones, F2 – Settings, sum zone setting
Measurement Process ± [ ] %
 Fixed Calibration Distance [] cm to be available for Alt+3 Gamma on Argos and Sirius
models. It’s not available for Cronos and GEM-5 model since distances are expected to
be different. [A][S]
11. F3 - Setup, F3 - Detection Zones, Shift+F5 - Global Settings. [A][S][G][C]
 Changed Measurement Process ± [ ] % to Calibration Process ± [ ] %. Pressing
“F7 = Measurement Process ±” applies this to F3 - Setup, F3 - Detection Zones,
F3 - Calibration, setting Calibration Process ± [ ] %
 Added Measurement Process ± [ ] %. Pressing “F7 = Measurement Process ±” applies
this to F3 - Setup, F3 - Detection Zones, F2 – Zone Settings, setting
Measurement Process ± [ ] %
12. F3 - Setup, F3 - Detection Zones, F8 - Total Gamma Activity. [A]
 Expanded Include Gamma Detector # [] settings to all available gamma detectors
