Buffer considerations

When the SourceMeter is in the process of storing readings, configuration changes affect
what gets stored in the buffer. These storage considerations and restrictions are summa-
rized in Table 6-3.

are made while the SourceMeter is storing readings.
Changing V, I, or Ω measurement function
• If you started with only a basic measurement function selected, the buffer will track
a basic measurement function change. For example, if you started in volts and
changed to current, the buffer will store the current readings.
• If you started with MATH, REL, and/or LIMITS enabled, the buffer will stop stor-
ing readings if you change the basic measurement function. Storage will continue
if you return to the original configuration.
