Grounding Voltage Measurement
It measures the Ground – Neutral Voltage in the range of 0 – 30 V AC with 2% accuracy and gives a reference value in terms of grounding quality.
Where the grounding is weak, the probability of the active devices breaking down is very high, so it is very important to measure this parameter.
It is not a physical sensor. BS-6000 Series V models have 1 as standard.
