V/Hz, Ω, Temperature, and A/Hz Measurements
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 55 V AC or 70 V DC, a danger symbol
appears at the display: .
