Measurement with Shunt

The connecting leads to the shunts should be as short as possible in order to prevent
interference and noise voltages.
To avoid possible electric shock or personal injury:

Where the current to be measured exceeds the rating of the direct current connection, an
external triaxial shunt should be used, see Figure 5-3. Fluke triaxial shunts are
recommended as they provide high accuracy across the full frequency range. Standard
linear shunts may produce excessive errors due to the possible presence of high
frequency that components experience with electronic loads. The NORMA internal shunt
is optimized for such loads.

XW Warning
Do not touch sensing terminals. The sense terminals at the
shunts are powered with the same voltage as the power
connections.
Shunts are not isolated. Never touch the sense terminals at
the shunts.
Risk of injury when touching connections, internal circuits,
and measuring devices that are not earthed.
Always adhere to the instructions regarding the connection
sequence (see Chapter 5, "Connecting Sequence").
