5.2. NON-CONTACT AC VOLTAGE DETECTION (NCV)
The maximum input AC voltage is 600V. Do not measure voltages
exceeding the limits given in this manual. Exceeding these limits could
result in electrical shocks to the user and damage to the instrument.
1. Select the position NCV. The "EF" indication is displayed
2. Move the instrument to the AC source (see Fig. 4)
3. Note the intermittent flashing frequency of the AC voltage detector (see Fig. 1 – part 2)
and the sound emitted by the instrument which gradually increases in intensity close to
the AC source
4. The "- - - -" indication, the maximum flashing frequency and the sound in the closest
point to the AC source is shown by the instrument
