MAinS rAnGE Line voltage
measuring range
Here: The 6 V, 60 V or 600 V range (default) can be selected as the voltage measuring range.
MAinS.F Line voltage frequency Selection of the measuring signal line frequency is required for the calculation of the TRMS
half-wave value: 50 or 60 Hz. It determines whether a TRMS value is generated every 8.33 ms,
or every 10 ms.
nS Siemens Unit of measure for electrical conductivity in the SI units system.
Reciprocal value of electrical resistance: S = 1/Ohm = A/V, nS = nanoSiemens

r_SL Low-resistance
measurement
The resistance of a protective conductor connection limits, for example, the length of an extension
cable or a cable reel, or may not exceed a specified limit value. The same applies to resistance
between housing and mains plug or device plug. The limit value can be set within a range of 1 to
60 ohms.
