7. Set the relative value
Turn on or off the relative operation function. When the relative operation is turned on, the
displayed number is the actual measured value minus the set relative value. (For details on
how to set the relative value, refer to the section "Mathematical Operation Function" in this
chapter).
8. Graphical display
The user can change the display mode of the measured data through [Display], and there
are four display modes, "Digital", "Bar", "Tendency" and "Histogram" figures. Please refer to
the section "Display Mode" for details.
9. Mathematical operation
The user can perform mathematical operations (statistic, limit, relative) on DCI
measurement readings. For details on how to use this function, refer to the section
"Mathematical Operation Function" in this chapter.
Tip
When measuring small resistors, it is recommended to use relative value calculation, which
can eliminate test wire impedance errors.
4-wire Resistance Measurement
When the measured resistance is small, the resistance of the leads and the contact
resistance in the test circuit can lead to additional errors, so a 4-wire system is necessary for
more accurate measurements.
Operation Steps
1. Press the
resistance measurement menu, as shown in Figure 0–24.
