When In/Iref[%] is selected with the F4 key
Measured values are those in a selected data frame. They are expressed as the ratio to the
reference fundamental current.

Description
Harmonic
orders 1st to
40th.
The 1st
order is the
reference
current
*1
,
THC
*2
and
PWHC.
*1. Instantaneous rms current is substituted for reference current Iref.
*2. THC denotes THC/Iref; PWHC denotes PWHC/Iref. Iref is displayed as "-----," because it is
determined at the end of the test.
Limit value (%) Measured

When “ Average ” is
selected with the
F1 key
Ratio of the
Ave[%] to limit
value when
“ Average ” is
selected with the

Ratio of the
Max[%] to limit
value when
“ Maximum ” is
selected with the
F1 key
(Lower)
Maximum value
(%) from the
beginning of the
test
When “ Maximum ”
is selected with
the F1 key
“ ----- ” means there
is no numeric value
to be displayed:
• When limit values
do not exist
• When a
calculated limit
value is less than
0.0001 A (0.001
A in the 10 A
range or higher)
Display color

“ ----- ” means there
is no value to be
