6.5 The exposed contact electrode of the potential
indicator should be positioned such as to make
contact with the voltage source to be measured.
For neon model indicators the neon’s within the
PVC tube will be illuminated to inform the operator
that a voltage greater than the threshold voltage
of the detector is present. For the digital model
indicators the display will indicate a reading to
inform the operator of the exact value of the
voltage present.
Never hold the potential indicator between the
hand guard and the exposed contact electrode.
6.6 The potential indicator must be applied in turn to
each phase of the system under test.
6.7 After use the potential indicator must be proof
tested on a suitable proving unit such as the
Seaward Electronics PH3 proving unit.
6.8 Type digital indicator. Once testing is complete
unclip the earth clamp from the reference earth
point. Disconnect the earth cable from the bottom
of the potential indicator and replace the protective
cap over the plug of the potential indicator.
Digital indicator only. Always ensure the earth
cable is disconnected from the potential
indicator when not in use to prevent the
battery from being fully discharged.
