Ð Select the measuring range of the multimeter as a function of the
measuring range and the transformation ratio of the clip-on trans-
former.
Ð Connect the measurement cables as shown.
Ð Set switch to position „ON“.
Ð Scan the electrical circuit with the clip-on transformer.
Ð Read the measured value by making allowances for the transforma-
tion ratio of the transformer.
Ð Disconnect the clip-on transformer from the electrical circuit before
separating the measurement cables from the instrument!
