5.1.4 Transient Overvoltages
The multimeters are protected against transient overvoltages of up to 8
kV with wave-front durations of 1.2 ms and halftimes of 50
μ
s in the
voltage measuring range. If longer pulse durations are expected, for
example when conducting measurements at transformers or motors,
we recommend the use of our KS30 measuring adapter. It provides
protection against transient overvoltages of up to 6 kV with wave-
front durations of 10, and halftimes of 1000
μ
s.
Continuous load capacity is 1200 V
RMS
. Additional influence error
caused by the KS30 measuring adapter amounts to approximately -
2%.
5.1.5 Voltage Measurements at Above 1000 V
Voltages of greater than 1000 V can be measured with a high-voltage
probe, e.g. the HV3
1)
or the HV30
2)
from Dranetz-BMI. It is abso-
lutely essential to earth the ground terminal in this case. Observe all
applicable safety precautions!
1)
HV3: 3 kV
2)
HV30: 30 kV, for (DC) voltages only
