8062A
Instruction Manual
2-22
A quick way to check for shorted or open junctions is to reverse the test
leads. If the junction indicates the same in-scale reading both directions, it is
probably shorted. If the junction indicates an overrange both directions, it is
open.
2-21. Relative (REL)
The relative function allows you to store any reading as an offset or relative
reference value. When you press the REL button, the REL indicator appears
in the upper right corner of the display, and the 8062A stores the next
measurement in a register along with the function and range. Subsequent
measurements are displayed as the difference between the measured value
and the stored relative reference (refer to Figure 2-15).

1.
Select range and function
(any measurement function:
V, A, Ω, or ).
2.
Heed input overload limits (Table 2-2),
connect test leads and take desired
measurement (example shows a 1.5000V measurement
has been taken and displayed):
3.
Press the REL button to store the next measured value
as relative reference (display becomes zero and the REL
indicator is displayed). The stored reference is subtracted
from subsequent measurements:
4. To cancel the relative reference, press REL.
The REL
indicator disappears and the original measurement value
is reestablished:
