Frequency range: 40Hz ÷ 10kHz ;
(**) For values <5% of each range add 20dgt to the accuracy
(*) Frequency range of this range: 40Hz ÷ 1kHz
For non-sinusoidal voltages, consider the following crest factors (CF):
1.4
 FC < 2.0  Add 1.0% reading to accuracy
2.0
 FC < 2.5  Add 2.5% reading to accuracy
2.5
 FC  3.0  Add 4.0% reading to accuracy
Accuracy in AC+DC mode: AC accuracy + DC accuracy + 1.0%reading
Accuracy in HFR mode: AC accuracy + 1.0%reading (40Hz
 400Hz)
Cutting frequency in HFR mode: 800Hz (-3dB) ; Characteristic attenuation: approx. -24dB
