Measuring currents and voltages

Measuring currents and voltages used

The following measuring currents and voltages are used, depending on the measuring range.

Measuring range

Typical measuring voltage (max.)

Typical measuring current.

-1 (0 -100 mΩ)

~ 4.5 mV (3.0 V)

~ 45 mA

0 (100 mΩ -1 Ω)

~ 45 mV (3.0 V)

~ 45 mA
