4.6.3 Precautions

The Model 2010A 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.

The Analyze Function

Normally, all of the functions automatically switch back to the

Analyze

function when they have completed their assigned operations. Pressing the
