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 grea-
ter 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: .
