Multimeter Specifications
ACV CREST FACTOR MEASUREMENT
26
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.
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/total rms). Applies to rms and average
measurements.
Range % of Reading % of Range
200mV, 20V 0.05 0.1
2V, 200V, 750V 0.07 0.01
AVERAGE ACV MEASUREMENT
Normal mode rms specifications apply from 10% to 100% of range, for 20Hz–1MHz. Add 0.025% of range uncertainty for 50kHz–100kHz, 0.05%
of range uncertainty for 100kHz–200kHz, and 0.5% of range uncertainty for 200kHz–1MHz.
