PD Tester Overview

Using the PD Tester couldn't be easier. Simply connect a cable or panel to the tester's input and output connectors, and view the results on the color LCD display.

The tester examines each piece of equipment for short circuits, open circuits, reversed wires, and even phase rotation. Additionally, for panels and quad box strings, the phase of the output is identified both by phase-letter as well as color code. This facilitates color-coding outlets depending on the phase they use--an incredible time-saver for balancing the load out in the field!

Microprocessor Based

Because the PD Tester is microprocessor-based, the diagnostics are not limited to simple "Pass/Fail" indicators.

·        Automatic identification of cable type
(4-wire in this example)

·        Open circuits (Neutral in this example, which is a failed test)

·        Short circuits (not shown in this example)

·        Reversed wiring (Phase reversal in this example, which is only cautionary)

·        Two methods of identifying phase
(Text and Colored Indicators)

Adaptable

The tester was designed with flexibility in mind. This has two primary benefits: Ease the workload on the operator, and the ability to test non-standard cables or panels.

·        Cable adapters can be constructed with lighter weight materials to make it easier to connect panels and other devices to the tester. In this example, #2/5 conductor was replaced with #10/5 conductor, and the cumbersome pin and sleeve cable end was replaced with an easy to use NEMA L21-20 connector.

·        Special adapters can be constructed to connect non-standard outlets and cables to the tester without redesigning the tester, or having dedicated outlets in the tester.

·        On the other hand, if your system frequently uses non-standard cable types, you can order the tester with these cable connectors permanently installed. For example, if a significant amount of your P.D. uses 600V pin and sleeve, the tester can be ordered with these connectors built-in.

Sample Adapter Cable

Testing a Panel

Test ALL of your Equipment

It makes no difference to the tester whether you are testing cables or panels, if the device can be connected to the tester, it will test it.

The panel in this example uses a 3-phase, 5-wire input and single-phase, 3-wire output. The tester will identify this type of configuration and diagnose the connections accordingly.

Notice the use of the light-weight adapter cable to connect the panel's input to the tester. Nobody likes working with #2/5 cable! The same approach is used for Cam-Lok connected panels.
