* According to safety rules, 1000V range is limited to 600V.
4.2.3 Alternating voltages at low impedance (V
AC LowZ True RMS)
The input impedance is 270kΩ.
A low input impedance serves to eliminate the effects of
interference voltages due to the supply network, and makes it
possible to measure an AC voltage with a minimum of error.
