(In this display, the range is fixed.)
Difference Display (REL Δ)
The CA0 shows the value of the measured value minus the reference value.
) Measure (input) the reference value.
2) Press REL Δ/% to confirm the reference value. ("Δ" is displayed, and the range is held.)
) Measure (input) the measured values. The displayed values vary depending on the
measurement function.

Percentage Difference Display (REL%)
The CA450 computes the value of (Measured value – reference value)/reference value and
displays the result as a percentage.
) Measure (input) the reference value.
2) Press REL Δ/% to confirm the reference value. ("Δ" is displayed, and the range is held.)
) Press REL Δ /% again. ("%" appears.)
) Measure (input) the measured values. The displayed values vary depending on the
