Phase Information
Under the Measurement title, there is a drop-down list, which allows you to select the measurement type. This
can be Single-Phase, Three-Phase or Belted Cable (also known as three core cable with one accessible earth).
The Single-Phase option should be selected when each phase is tested separately. For single-phase
measurements, only channel 1 is used. Three-Phase should be selected when all three channels are used
simultaneously with separate HFCTs. Belted Cable should be selected when the earth conductor surrounds all
three cores, and it is not possible to attach an HFCT to a separate earth conductor for each core. The drop-
down list is shown in Figure 31.

Measurement selection
For Belted Cable, no phase information is required and so the configure window is not needed as the phase
setting is locked to belted. For Single-Phase and Three-Phase, once the option for the measurement type has
been selected, the Configure button to the right must be clicked to set the phase for the measurement.
For single-phase configuration, first, select the phase naming convention from the drop-down list as shown in
