3. V2AC low level AC voltage measuring input
Measuring input for low-level AC voltage of 0...3V in a frequency range of
15...400Hz (for example, for low-power measuring transformers, or to
connect a current clamp).
The software changes automatically between the measuring ranges 0.03V,
0.3V and 3V. For details about the accuracy of the individual ranges, please
refer to ”3V V2 AC Input” on page 16-25.
4. VDC voltage measuring input 10V DC
Measuring input for DC voltage of 0...10V. The software changes
automatically between the measuring ranges 0.01V / 0.1V / 1V / 10V.
Note: The V1 AC and V2 AC inputs are galvanically connected. All other
inputs and outputs are separated.
1. IAC/DC current measuring input 10A AC and DC
Measuring input for AC and DC current of 0...10A,
depending on the selected test card. AC current is
measured in a frequency range of 15...400Hz.
For both AC and DC current measurement, the
software changes automatically between the two
measuring ranges 1A and 10A. In both ranges the
measuring error is <±0.2%.
A 10A FF (10 Amps very quick-acting wire fuse
6.3x32mm) protects the 0...10A AC/DC current
measuring input.
2. V1AC voltage measuring input 300V AC
Measuring input for AC voltage of 0...300V. AC voltage
is measured in a frequency range of 15...400Hz.
During measurement, the software changes
automatically between the measuring ranges 0.3V, 3V,
30V and 300V.
For details about the accuracy of the individual ranges,
please refer to ”300V V1 AC Input” on page 16-23.
