The equipment has the following features:-

4.1 The units consist of an element manufactured from a high quality PVC tube. The tube supports and isolates a chain of high value internal resistors.

4.2 The total encapsulation of the load element prevents any internal tracking or leakage.

4.3 A handguard in the form of a digital display housing on the handle section of the unit prevents the operators hands from straying towards the high voltage ends of the potential indicator.

4.4 An additional phasing rod (secondary element) manufactured from the same high quality PVC as indicated in section 4.1 and supports / isolates another chain of high value resistors.

4.5 The phasing rod is also manufactured with a handguard and provides total encapsulation of the load elements.
4.6 The digital voltage display is incorporated into the handguard housing.
4.7 An external domed contact electrode ensures a positive contact with any terminal required to be tested.
4.8 An insulated earth cable is connected to the potential indicator section of the equipment through the handle. The earth cable is detachable. This earth cable is fitted with a suitable clamp that allows the operator to reference the potential indicator to a suitable earth.
4.9 Labels present on the equipment and accessories are there to ensure safe use of the equipment.

6.0 Operation

6.1 Potential Indicator/Voltage measurement

6.1.1 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.

6.1.2 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.

6.1.3 Before use the digital unit must be proof tested on a suitable proving unit such as the supplied Seaward PH3 proving unit. Refer to section 9.0
6.1.4 The earth clamp attached to the free end of the insulated earth cable must be attached to a suitable earth point i.e. an earthed strip of frame or an earth electrode.
6.1.5 The contact electrode of the digital unit should be positioned such as to make contact with the voltage source to be measured. The digital display will indicate the value of the voltage present.

Never hold the potential indicator between the hand guard and the exposed metal head.

6.1.6 The potential indicator must be applied in turn to each phase of the system under test.

6.1.7 After use the potential indicator must be proof tested on a suitable proving unit such as the supplied Seaward PH3 proving unit. Refer to section 9.0

6.1.8 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.

Always ensure the earth cable is disconnected from the potential indicator when not in use to prevent the battery from being fully discharged.

6.2 Phase Detection

6.2.1 The insulated earth cable, 2m in length, along with the 600mm linking cable permanently connected to the phasing rod are connected by means of a plug and socket arrangement to the bottom of the handheld section of the potential indicator.

6.2.2 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.

6.2.3 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.

6.2.4 Before use both the digital unit and phasing rod must be proof tested on a suitable proving unit such as the supplied Seaward PH3 proving unit. Refer to section 9.0
6.2.5 The contact electrode digital unit should be positioned such as to make contact with a conductor or terminal of the first circuit. The digital unit will display the value of any voltage present at the contact electrode.
6.2.6 The contact electrode of the phasing rod is then, applied, in turn, to each phase conductor or terminal on the second circuit.

Never hold the potential indicator between the hand guard and the exposed contact electrode.

6.2.6 The display will now indicate the potential difference between the two contact electrodes i.e. a reading proportional to phase angle difference and the rated voltage of the system when the digital unit and the phasing rod are between different phases. When the digital unit and phasing rod are connected to the same phase, the display will indicate a reading <900V depending on the capacitance to earth of the primary and secondary elements.
6.2.7 After use both the digital unit and phasing rod must be proof tested on a suitable proving unit such as the supplied Seaward PH3 proving unit. Refer to section 9.0
6.2.8 Once testing is complete unclip the earth clamp from the reference earth point. Disconnect the earth and linking cable from the bottom of the potential indicator element of the phase comparison equipment and replace the protective cap over the plug of the potential indicator

Always ensure the earth and link cable are disconnected from the potential indicator when not in use to prevent the battery from being fully discharged.

7.0 Battery Charging

A “BAT” sign on the digital display of the potential indicator unit of the Phase Comparison Equipment denotes that the battery requires charging.

During prolonged storage periods the battery will discharge. In order to increase the battery life the instrument should be charged periodically.

7.1 Remove the protective cap from the connector on the bottom of the hand held section of the digital unit.

7.2 Insert the 6 pin socket fl ying lead from the PSU100 battery charger – Seaward Part 124A912 into the connector and fi rmly screw into place. Connect the mains lead from the charger to a 240VAC 50Hz supply and switch on.

7.3 When mains power is applied to the battery charger, one LED is continuously illuminated and a second LED will flash approximately every 5 seconds to indicate the battery is being charged.

7.4 After approximately 14 hours the continuously illuminated LED will be extinguished indicating charging is completed.

7.5 On completion of the charging cycle, disconnect the battery charger supply from mains, disconnect the 6 pin socket from the base of the potential indicator and replace the protective cap over the plug.

Do not use the potential indicator on a high voltage circuit while the battery is on charge.
