V/Hz, , Temperature, and A/Hz Measurements
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 com-
parator for dangerous spikes, because these do not appear at the
display when the low-pass filter is used.
Where U > 45 V, a danger symbol appears at the display.
