2.3.2. Customizing ID Numbers and Descriptions
If you wish, you can change the instrument ID Numbers and
Descriptions by double-clicking on an instrument entry in the Configure Instruments dialog. This will open the Change Description or ID dialog (Fig. 4). It shows the physical Detector location (readonly), and allows you to change the ID Number and Description.

NOTE FOR GAMMA TOTAL USERS
The filenaming conventions for EDF’s Gamma Total effluent reports (Section 5.5.1.9) are based on a single-digit identifier for the MCBs used for data acquisition. When first setting up
GammaVision, be sure to choose instrument ID numbers that each end with a unique digit, e.g., 0–9 (for instance, 901, 22, 13, 4, 375, and so on). Note that in Fig. 2, two of the instruments in the list share 1 as the final digit of their ID number, and two share 4 as the final digit.
To avoid having two MCBs that generate reports with the same device identification number, two of these MCBs should ideally be reassigned ID numbers with unique final digits.
Make the desired changes and click Close. Any changes you have made to an ID number or description will then be written back to the corresponding Detector.
If a modified description has already been applied to a particular instrument, you can restore the default description by deleting the entry in the Description field and re-running MCB Configuration. After MCB Configuration runs, the default description will be displayed.
2.4. Caution: Running the MCB Configuration Program
Can Affect Quality Assurance
Detector identification in GammaVision is based on the instrument ID number and description assigned to a Detector by the MCB Configuration program. Instrument ID number and description are assigned when MCB Configuration polls the local PC and network for attached ORTEC
MCBs and then builds a Master Detector List of the instruments found. This instrument identification is then used for all QA measurements.

Once you have established QA settings for those detectors and subsequently collected data using
them, if you then re-run the MCB Configuration program for any reason, you must ensure each instrument is still assigned its previous instrument ID number and description before collecting
any more data. Allowing the MCB Configuration program to assign a new instrument identification to a detector, and then using that new identification, interrupts the orderly accumulation of QA records. This is because GammaVision treats the renumbered detector as new, with zero
“previous QA measurements” and with potentially incorrect QA settings.
If you must re-run the MCB Configuration program, you can avoid any renumbering problems either by not renumbering instruments or by manually editing the instrument numbers for all of the Detectors on the Master Detector List for your PC. Doing so requires that you keep a separate record of the ID and Description for each MCB on your system. Note spelling, spacing, and
uppercase/lowercase; these details will be necessary when recreating the Description text
string. Let us use the following example to illustrate the process:
Suppose you are using two MCBs for your GammaVision measurements and in your original
MCB Configuration you configured them as 1 DSPEC PRO 1 and 4 DSPEC PRO 4. This is depicted in Fig. 5. The numerical prefixes 1 and 4 are the IDs and the corresponding text strings are the Descriptions.

Pro MCBs.
Suppose we add one new MCB to the system and remove two. We must then manually re-run
MCB Configuration to add the new instrument to the Master Detector List. Suppose we then find that our two DSPEC Pro units, originally assigned IDs of 1 and 4, have been renumbered with IDs of 2 and 3, respectively. Before closing the Configure Instruments dialog, double-
