There are six range limits in Levsine mode: 10 mV, 40 mV, 100 mV, 400 mV, 1.3 V,
and 5.5 V. When set to “auto” the calibrator uses your voltage setting to
automatically set the range limit that provides the most accurate output. When set to
“locked” the range limit remains fixed and you can decrease the voltage down to 0 V
within any range limit.
For example, assume the range limit is 40 mV. If you set the 40 mV range to “auto”
and then enter 1 mV, the calibrator will adjust the range limit to 10 mV and will
output 1 mV from within the 10 mV range. If you set the 40 mV range to “locked”
and then enter 1 mV, the calibrator will output 1 mV from within the 40 mV range.
The default range setting is “auto,” which should always be used unless you are
troubleshooting discontinuities in your oscilloscope’s vertical gain. The range setting
will always return to “auto” after you leave Levsine mode.
