Then I switch to scaler count time to 60 seconds. Here I conducted two tests. The results of the first test were 1915 with a small 3 in the r/h corner. This means raised to the 3rd power, correct?

The second run is 1938 with a small 3. Obviously something is amiss with numbers like 1915000, and 1938000.

The Ludlum 2241 display has six digits: the four big digits which reside in the main part of the display, and the two small digits which are tucked away in the bottom-right corner of the display. For reasons which I cannot explain, Ludlum likes to group these two sets of digits into a single 6-digit number (even though the digits are spatially separated).

If you are seeing "1915" in the four big digits, and a "3" (or "03") in the smaller digits, then the number you are looking at would be the "3" (small digit display) followed by "1915" (large digit display). A "3" followed by "1915" would translate into "31915". Likewise, having the large digits show "1938" in conjunction with a "3" in the small digits would correspond to "31938". Also take note that both of these numbers corroborate well with the other source check results you've received.

On the Ludlums I've used, you can watch the counts tally up on the display in real-time during counting. When you do your 1-minute count, keep your eyes fixed on the Ludlum's display throughout the count cycle.

- The counts displayed on the large digits should reach "9999" shortly before the 20-second point.
- Immediately after that, the counts shown on the large digits should roll over to "0000", and "1" (or "01") should appear in the small digits.
- The counts shown on the large digits should again reach "9999" at approximately the 40-second point.
- Immediately after that, the counts shown on the large digits should roll over to "0000", and the small digit display should change from "1" (or "01") to "2" (or "02").
- And finally, shortly before counting terminates the large digits should roll past "9999" one last time, and the small digits should change from "2" to "3". Based on your earlier results, the large digits should come to a stop around 1900-1950 when the one minute counting cycle completes
