current clamp around the conductor until the highest value is di-
splayed on the screen. With the display of the highest value the

For three-phase conductors the maximum values can be measured
at different values, depending on the phase load. The conductor can
be locked using the conductor lock (8).

the clamp from UUT and read the measurement value displayed on
the screen.
