4.3.12 Relative Value Display (REL Δ/%)
The CA0 can calculate and display relative values that represent the difference or percentage
from a reference value.
(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.
• For DCmA measurement (including loop power measurement):
Main display value:
Measured value – reference value
Subdisplay value:
(Measured value – reference value)/current span
setting × 100 (%)
• For measurement types other than DCmA:
Main display value:
Measured value – reference value
Subdisplay value:
Reference value
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
measurement function.
• For DCmA measurement (including loop power measurement):
Main display value:
(Measured value – reference value)/current span
setting × 100 (%)
Subdisplay value:
Reference value
• For measurement types other than DCmA:
Main display value:
(Measured value – reference value)/reference
value × 100 (%)
Subdisplay value:
Reference value
