Non-ContactPhaseIndicatorandCableBreakDetector
Before using the BENNING VT 1 phase indicator and cable break detector: Please read the operating
manual and absolutely observe the safety instructions!
1. Safetyinstructions
- Check the phase indicator and cable break detector for correct functioning immediately before and
after using it (see chapter 3)! Do not use the indicator, if one or more indications are not working or
if it does not seem to be ready for operation!
- During the tests, touch the indicator at the red handle behind the grip limit
the white probe tip
- The indicator must be used only within the stated nominal voltage range from 200 V to 1,000 V AC
and in earthed mains supply circuits of overvoltage cat egory CAT III 1,000 V or CAT IV 600 V for
phase-to-earth measurements.
- The BENNING VT 1 phase indicator and cable break detector detects fields of phase/external
conductor voltages from approx. 200 V alternating voltage (AC) on. Direct voltage (DC) fields will
not be detected!
- Please observe that work on live parts and electrical components of all kinds is dangerous! Even
low voltages of 30 V AC and 60 V DC may be dangerous to human life!
- The BENNING VT 1 phase indicator and cable break detector is not a substitute for a two-pole
voltage tester such as e.g. the DUSPOL® to determine the ab sence of voltage.
- The following factors might affect the correct functioning of the phase test and cable break detect:
- excessive distance to the phase (external conductor) to be tested
- excessive insulation and shielding of the phase (external conductor)
- protective clothing and insulating conditions on site
- constructional differences of sockets / CEE couplings with recessed contacts, e.g. 63 A CEE
coupling
- mains failures or lacking mains quality
- battery condition
- Do not operate the device with the battery compartment being open.
- The indicator is designed for being used by qualified electricians and under safe working condi-
tions.
- The indicator must be protected against contamination and damaging of the housing surface.
