The active low-pass filter is indicated by the FILTER display. The
multimeter is automatically switched to manual measuring range
selection.
Specified measuring accuracy is not reached with signals of
greater than 100 Hz when the filter is active.
Voltage Comparator for Displaying Dangerous Voltage
The input signal or measuring signal is checked by a voltage
comparator for dangerous spikes, because these do not appear at
the display when the low-pass filter is used.
At voltages of greater than 30 V AC or 35 V DC, a danger symbol
appears at the display: .
