1.4 Setup the Equipment

The setup of this equipment has been minimized by careful consideration of the operator during design. The DTS-60xx one-piece construction permits convenient portability. The DTS-60xx test set requires that the unit is operated with the control panel in the horizontal position, to keep oil level over high voltage transformer in the high voltage tank.

1. Select a location for the unit that will allow easy viewing of the User Interface

2. Be sure that all the controls are off, in their deenergized state.

3. Remove all components and oil vessels from the test chamber

4. Install the input line cord into the Input Power receptacle

5. Connect the line cord to a suitable (120V or 230V, see Specifications Table) grounded power source.

6. Select the desired Test cell. Fill in with sufficient insulating liquid for the testing to be performed.

7. Clean the Test Cell and Electrodes thoroughly and adjust the electrodes to conform with the proper ASTM Specification. Be sure the electrodes are securely tightened on the adjustment posts inside the oil vessel.

Use Isolation transformer (1/1) if the electrical installation has neutral earthing.

All the oil vessels designed and made by High

Voltage Inc. have interchangeable posts and electrodes. These oil vessels were designed to conform to the ASTM test

DTS-60A OPERATORS MANUAL

specifications requiring simple disassembly for cleaning. This design greatly reduces the time and effort required keeping your oil vessels in top operating condition.

The operator of this equipment must

use good judgement and follow all safety precautions noted in this guide to ensure the protection of himself and others in close proximity to the test area. Failure to follow the instruction could result in injury or death.

1.6 Startup the Equipment

1. Ensure that setup has been completed as noted in

2. Turn on Main Power.

4. After the self-tests are completed, the unit proceeds with

the last selected test (Simple Test, Standard or UserDefined).

5. The unit will display the Electrode Warning message (see

paragraph 1.3.3) and it will wait for ‘ENTER’ to be pressed.

6. The user may open the lid, check the electrodes (type and

spacing) and finally fill the appropriate test vessel with insulating oil.

7. After closing the lid, the user should press the ‘ENTER’ key

in order to initiate the test procedure.

Whenever you see an ERROR message contact with the service or the distributor.
