Hi Ulrich, Thanks for the insight! I tried manually adjusting the value of CalByte 50 (as per Magnus' suggestion), but it did not make the problem go away. There is interaction between this adjustment and the CalByte 4 adjustment for timebase accuracy, and when all was said and done, I didn't notice any significant difference in the offset.
Where in the manual does it describe the procedure to minimize the bias? It's definitely not where I would have expected it to be!

My understanding a few years ago when I acquired the counter was that this bias is not due to a "adjustment" in the normal sense but to set a parameter in the counter's eeprom to a correct value. Since this parameter is limited to a certain precisison you can make some effort in minimizing this bias but you should not expect to make it exactly zero. The manual explains how to do but you do not find the procedure where you would have expected it.
