Figure 2. Description of Functions
Measurement of Interference Voltage (UST)
Fullwave rectification for DC and AC (DC without operational sign, AC signal sinus calibrated for r.m.s. values). If limit values are exceeded no measurement will be started.
Measurement of Interference Frequency (FST)
For interference voltage >1 V its frequency is derived from the period time.
