Measurement of alternating voltages in the
range of 16…400 Hz
 In addition, the voltage values are indicated on
the LED scale as follows: 12, 24, 50, 120, 230,
400, ≥690 V, together with the presence of AC
voltage ("AC" indicator light is active).
 The frequency of measuring voltage for the
scale: 16…400 Hz.
