Input impedance :
1MΩ // less than 100pF.
AC Conversion Type :
3350 : AC Conversion are average sens-
ing rms indication calibrated to the rms
value of a sine wave input.
3355 :
*1 : Reading less than 15% of full scale
(4000 digits) is needed to add 4 digits and
the settling time will increase.
AC Conversions are ac-acoupled, true
rms responding, calibrated to the rms
value of a sine wave input. Accuracies
are given for sine wave at full scale and
non-sine wave below half scale. For non-
sine wave add the following Crest Factor
corrections :
For Crest Factor of 1.4 to 2.0, add 1.0%
to accuracy.
