5.1.3 Transient Overvoltages

The multimeters are protected against transient overvoltages of

up to 4 kV with wave-front durations of 1.2 ms and halftimes of

50 μs in the voltage measuring range. If longer pulse durations are

expected, for example when conducting measurements at trans-

formers or motors, we recommend the use of our KS30 measur-

ing adapter. It provides protection against transient

overvoltages of up to 6 kV with wave-front durations of 10, and

halftimes of 1000 μs. Continuous load capacity amounts to

1200 V

RMS

. Additional influence error caused by the KS30

measuring adapter amounts to approximately -2%.
