and/or R

> 100R

, R

> 50kΩ and/or R

> 50kΩ, if the instrument carries out the test

the accuracy of the instrument is ±(10%Reading)

= resistance of the voltage circuit

= resistance of the current circuit

= earth resistance

(**) Automatic selection of the range.

Measuring frequency 125Hz / 75Hz/ 41.66Hz

Measuring current 10mA

Open-terminal measuring voltage 25Vrms

Waveform of measuring voltage: sine wave

Interfering voltage:

- amperometric circuit: the measurement is taken with the stated accuracy if the interfering voltage is ≤ 3V,

while for interfering voltages between 3 and 30V inclusive, the accuracy decreases progressively; with an

interfering voltage of about 30V the instrument does not perform the test.

- voltmetric circuit: the measurement is taken if the interfering voltage is ≤ 3V; in case of higher voltages

the instrument does not perform the test.
