AC COUPLING:
For AC only coupling, add the following % of reading:
1–10Hz 10–20Hz 20–50Hz 50–100Hz 100–200Hz
Normal Mode
(rms, average) — — 0.41 0.07 0.015
Low Frequency Mode
(rms) 0.1 0.01 0 0 0
For low frequency mode below 200Hz, specifications apply for sine wave inputs only.
AC+DC COUPLING:
For DC>20% of AC rms voltage, apply the following
additional uncertainty, multiplied by the ratio (DC/AC rms). Applies to rms
and average measurements.

ACV CREST FACTOR MEASUREMENT
11
CREST FACTOR = Peak AC / rms AC.
CREST FACTOR RESOLUTION: 3 digits.
CREST FACTOR ACCURACY: Peak AC uncertainty + AC normal mode rms
uncertainty.
MEASUREMENT TIME: 100ms plus rms measurement time.
INPUT CHARACTERISTICS: Same as ACV input.
CREST FACTOR FREQUENCY RANGE: 20Hz – 1MHz.
CREST FACTOR DISPLAY: Access as multiple display on AC volts.
