6.0 Operation
6.1 Type digital indicator. The insulated earth cable,
3m in length, is connected by means of a plug
and socket arrangement to the bottom of the
handheld section of the potential indicator.
6.2 Type digital indicator. On connection of the
insulated earth cable to the bottom of the handheld
section the digital display is automatically powered
up and zeroed ready for operation.
Always screw up the plug and socket securely.
The neon indicator will illuminate for an
energised system or for a proving unit test.
6.3 The earth clamp attached to the free end of the
insulated earth cable needs to be attached to a
suitable earth point i.e. an earthed strip of frame or
an earth electrode.
6.4 Before use the potential indicator must be proof
tested on a suitable proving unit such as the
Seaward Electronics PH3 proving unit. This
proving unit is supplied with digital indicator
models and is an optional accessory for neon
indicator models.
If no neon illumination occurs for a proving
unit test then the potential indicator must be
returned to the supplier.
