Why Does the Pulse Width of the NO-GO Output for the DL1540 Digital Oscilloscope Occasionally Decrease to 12 ms and What Causes This Change?

The NO-GO output is controlled by software. Thus, there may be fluctuations in the processing time depending on the sensing conditions. Since the signal remains low until the next determination can be accepted, this means that the processing time may fluctuate at the software level depending on the conditions. In any case, the minimum pulse width of 10 ms is guaranteed.
