Specified accuracy is valid for THD < 2 %
Frequency range 48 ÷ 52 Hz.
Notes to the parameters stated in chapter 5.1:
a) Stated accuracy of Continuity measurement is valid only if no parallel circuits
are connected to measured resistance.
b) Thresholds of auto-ranging may differ from the stated values.
c) R... Reading, D... Digit.
