4.6.3 Precautions
The Model 2010B allows a great deal of flexibility in choosing ranges for
automatic range switching. However, there are some pitfalls that are to be
avoided.
Ranges that work well together are:
• Ranges that have the same lower limits but upper limits that differ
by approximately an order of magnitude
• Ranges whose upper limits coincide with the lower limits of the
next higher range
• Ranges where there is a gap between the upper limit of the range
and the lower limit of the next higher range.
Range schemes that are to be avoided include:
• Ranges that overlap
• Ranges whose limits are entirely within the span of an adjoining
range.
Figure 4-2 illustrates these schemes graphically.

4.7 The Analyze Function
Normally, all of the functions automatically switch back to the
Analyze
function when they have completed their assigned operations. Pressing the
