Instrument Compatibility
The i400s is compatible with any Fluke Multimeter or any other
current measurement device that has the following features:
• BNC or Banana inputs
• Input accuracy of 2 % or better to take full advantage of
the accuracy of the Current Clamp.
• Input impedance of > 1 M Ω in parallel with up to 47 pF
Measurement Considerations
• Center the conductor inside the Current Clamp jaw.
• Make sure the clamp is perpendicular to the conductor.
• For optimal reading, make sure the conductor is
positioned between the alignment marks on the jaws of
the Current Clamp.
Observe the following guidelines when making measurements:
• Avoid taking measurements close to other current-
carrying conductors.
Operation
To use the i400s, refer to “Measurement Considerations” and
Figure 1:
1. If necessary, add a banana plug to the BNC connector
on the i400s.
2. Connect the clamp cable to the instrument. If using an
adapter, use the common and volts inputs of the meter
and switch it on.
3. Make sure the clamp and the measurement instrument
are set to the proper range. Use the range select
switch on the clamp.
4. The arrow on the top of the clamp must face towards
the load of the circuit.
5. Connect the current clamp jaws around the conductor
to be measured.
