Number of count : 5000
Range selection : automatic or manual (fixed in continuity mode)
Maximum open circuit voltage : 4 V
Detection threshold in continuity mode : 10 Ω to 20 Ω
Response time in continuity mode : < 10 ms
For measurements in 5 MΩ and 50 MΩ ranges, the use of shielded connection is highly
recommended.

To reduce the influence of the ambient electromagnetic fields on the measurement, it is
recommended to use shielded cables for measurements in 50 nF range.
