Readings as a Percent Change from Reference Point
(Zero %∆)
Select "ZERO %∆" to set the present upper reading as the
relative reference. Subsequent readings are displayed as a
percentage of variation (delta) from this point.
The figure below shows percentage change (tolerance)
when measuring a resistor:
Readings Displayed as a Percent of Scale (0%-100%)
Scaling starts automatically when both 0% and 100%
values have been entered as the scaled reference values.
Use the following procedure (example for Meter mode):
1. From the SCALE READING list box, highlight 0%-
100% and press .
2. Use
to highlight REFERENCE 100% and
press .
3. Measure the value that will represent 100%.
4. Highlight NOW (as the present 100% value) and press
to save the displayed value as 100%.
5. Repeat actions 2 to 4 for the 0% value.
6. Press (CLOSE) to activate scaling and remove
the window.
The present measurement result with respect to the
defined range with a 0% and 100% value appears now as
a scaled % readout.
