Setting the Recording Span (SPAN)
Set the left and right spans within the limits of an input range. In the SPAN menu item, the left-
hand value is the left span and the right-hand value the right span. Set the recording span within
the measuring range. The measurable limits vary depending on the measuring range you select,
as shown below.

Precautions in Measurement
• Input the voltage or current being measured at a level between 10% and 100% of the measuring
range. The DR recorder bases its calculations of all other parameters on the frequency of V1.
Extra care must therefore be taken when setting the input level of V1. If the input level fails to
fall within the given limits, there is no guarantee that the measurement of any other parameters
will be reliable.
