Input Protection : 1000VDC or 1000VAC rms
AC Frequency Response : 50Hz ~ 1KHz
Input Impedance : 10MΩ, <100pF
AC Conversion Type :
AC conversions are ac-coupled, true rms responding, calibrated to the
sine wave input.
For non-sine wave add the following Crest Factor corrections:
For Crest Factor of 1.4 to 2.0, add 1.0% to accuracy.
For Crest Factor of 2.0 to 2.5, add 2.5% to accuracy.
For Crest Factor of 2.5 to 3.0, add 4.0% to accuracy.
