readings. For frequencies above 100kHz, add 0.01% of
reading/

3 For 1% to 5% of range below 750V range, and for 1% to 7%
of 750V range, add 0.01% of range uncertainty. For inputs
from 200kHz to 2MHz, specifications apply above 10% of

6 For on-scale readings, no trigger delays, internal trigger,
digital filter off, normal autozero, display off, SREAL
format. These rates are for 60Hz and (50Hz). Rates for
AC Volts Notes
400Hz equal those for 50Hz. Applies for normal rms and
average mode. Low frequency rms mode rate is typically
0.2 readings per second.
7 For overrange readings 200–300% of range, add 0.1% of
reading uncertainty. For 300–400% of range, add 0.2% of
reading uncertainty.
8 In burst mode, display off. Burst mode requires autozero
refresh (by changing resolution or measurement function)
once every 24 hours.
9 AC peak specifications assume AC + DC coupling for fre-
quencies below 200Hz.
10 Specifications apply for 10-reading digital filter. If no
filter is used, add 0.25% of range typical uncertainty.

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.
