Features

Case Configurations

The Modiewark casing and handle are designed to channel a flashover around the internal circuit and into the battery housing. Please note any damage to the head of the Modiewark will result in failure the unit must be taken out of service and repaired.

The Modiewark tester can now be fitted with moisture and dust proof fittings for harsh environments and provides an IP63 rating.

Handles

The standard Modiewark is supplied with a sunrise (universal) fitting to allow the attachment of an insulation extension stick (hot stick) for all high voltage applications. A standard or plain handle can be requested without this fitting.

Self Testing Functions

The Modiewark is available with and without a self test function. This continuous self checking of the Modiewark non-contact voltage tester provides an essential safety feature that:

Provides a circuit testA signal is generated within the unit and is passed to the sensor detection plate and then through the entire circuit, proving the circuit is active and in good working order.
Provides a test to prove that the visual and audio indicators are working correctly.
The visual indicator is produced by three long life LEDs which provides the tester with two redundant light sources.Note: If audio or visual indicators are faulty take out of service and return for repair.
Battery Low Indicator.With a full battery charge of 4.5 volts the interval between the standby pulse is 1 second, as the battery power is lowered the pulse becomes further apart until it reaches 2.5 volts where the pulse becomes infrequent and stops. It is recommended to change the battery at a two second interval.

Please note that all Australian models must be sold with the self test function.

Battery Replacement

The Modiewark uses 3 C size Alkaline, Lithium or rechargeable batteries.

The batteries are placed in the handle with the positive side to the top. A battery strap is placed into the handle coil end first. When the batteries are placed in the handle shake to allow the battery strap to fall into the correct position.

Screw the handle with batteries inside to the head unit, with a firm twist in a clock-wise direction.

Operation

If using an insulation stick, place the unit onto the stick using the sunrise (universal) fitting or the bayonet adaptor fitting.

If using handheld, hold the Modiewark unit by the handle below the sunrise fitting.

1. Turn the unit on to the 240 volt switch setting (the first switch setting). This will allow for the most sensitive voltage detection.

2. Listen and watch for the self testing function which will start automatically. If this does not occur there may be a few possibilities to consider before taking out of service:

Remove the handle and check that the batteries are placed in the correct way and the battery strap is in place. Shake the handle and screw into place.
If the pulses are 2 to 3 seconds apart or greater this indicates a low battery status and batteries will need to be replaced.
If the self test is still unresponsive, the unit may be faulty. Take out of service and return for repair.
If the unit is a non-self test model, tap the head of the Modiewark with a finger and listen for an activation tone in time with the tapping.

3. To verify the tester using outside influences:

Place the tester against a live power outlet or equivalent above 110 volts AC.
Set the switch to 35kV overhead setting and place head of unit as marked against the spark plug of a running truck or car engine.
Use the Modielive tester to test the activation of the unit on the 240 volt setting.

4. Hold the detection plate side to the power source under test. A continuous tone will be heard indicating live voltage.

Underground Testing (URD)

To test underground power in a residential or industrial environment, the procedure must be carried out with a unit designed for this purpose. Due to the depth and moisture content of the soil, testing for a cable underground is difficult.

An accurate method of determining if URD connections are active is to test at a URD test point.

1. Hold the unit in the hand by the handle below the sunrise fitting or for higher voltages an insulation stick or hot stick is recommended.

2. Turn the unit on to the 240 volt switch setting (the first switch setting.) This will allow for the most sensitive voltage detection

3. Listen and watch for the self testing function which will start automatically. If this does not occur there may be a few possibilities to consider before taking out of service:

Remove the handle and check that the batteries are placed in the correct way and the battery strap is in place. Shake the handle and screw into place.
If the pulses are 2 to 3 seconds apart or greater this indicates a low battery status and batteries will need to be replaced.
If the self test is still unresponsive, the unit may be faulty. Take out of service and return for repair.
If the unit is a non-self test model, tap the head of the Modiewark with a finger and listen for an activation tone in time with the tapping.

4. To verify the tester using outside influences:

Place the tester against a live power outlet or equivalent above 110 volts AC.
Set the switch to 35kV overhead setting and place head of unit as marked against the spark plug of a running truck or car engine.
Use the Modielive tester to test the activation of the unit on the 240 volt setting.

5. Hold the detection plate side to the URD test point elbow under test. A continuous tone will be heard indicating live voltage.

6. If a tone is not heard at this point on the 240 volt setting move the tester closer to the conductor under test until the head of the tester is touching the conductor. At this point the voltage is below 50 volts AC. Please remember that voltages over 240 volts AC require personal protective equipment, gloves and hotsticks to increase the distance from the voltage source under test.

7. If the tester activates metres away from the known source, this may not prove that the signal being picked up is from that source. Use the voltage range switch to determine the voltage required for the voltage test, by moving the switch settings higher as you approach the power source under test. The unit is designed to activate 100 to 200mm away from the voltage source if hand held.
