Measurement Response Speed
The measurement response speed is the time required
until the analog output value stabilizes when input is
changed from 0% to 90% and from 100% to 10% of the
range in true rms measurement (RMS).
(1) FAST (0.2 sec)
Satisfies the specification at 45 Hz or more.
(2) NORMAL (0.8 sec)
Satisfies the specification at 10 Hz or more.
(3) SLOW (8.0 sec)
Satisfies the specification at 1 Hz or more.

1. Current Measurement
• In DC or AC+DC mode, the measurement is con-
ducted after zero adjustment has been performed.
• FAST, NORMAL, and SLOW indicate the mea-
surement response speed.
• When a low-pass filter (500 Hz) is used, the speci-
fications shall be satisfied at 60 Hz or less.
