5. Maintenance and inspection
 Check that the secondary wires are firmly connected to the power
transformer and measuring device.
 Check that the current transformer is properly connected.
 Remove any coarse dirt from the current transformer housing.
Contact with moisture, especially with the core, must be avoided at
all costs.
6. Troubleshooting
E.g. unexpected or incorrect values, inverted power
 Check the settings on the measuring device using these operating
instructions.
 Check whether the current transformer is installed in the direction of
energy flow on the conductor provided.
 Check that the current transformer is properly connected.
 Check the load requirements of the wires and measuring devices
connected to the current transformer. This must not exceed the
rated load of the current transformer (see type plate).
 If the points set out above do not resolve the problem:
Check whether there is any dust or other soiling between the two
parts of the core. If so, clean the surfaces carefully with a lint-free
cloth.
Avoid hand contact (sweat)!
