Page 3: Basic Operation
Basic Operation Warning: If a power source of 220V is connected to the input voltage terminal/receptacle, do not connect a110V device to the output load terminal/receptacle. Using Receptacles 1. Plug one end of the power cord into the input receptacle and plug the other end into the wall outlet. - Page 4 Using Terminals 1. Plug one end of the power leads into the input voltage terminal (left) and connect the other end of the test leads to the power source. 2. Plug the device power leads into the output load terminals. W, PF, V, and A will display for the device under test.
- Page 5 Using a Current Transformer Warning: Only personnel well trained in the principles of Current Transformers (CT) should attempt this test connection. When connecting a CT, follow the wiring diagrams and instructions below. 1. Connect the CT’s k terminal (entering the CT) to the power line that passes through the CT, and connect this k terminal to the input voltage black terminal (ground).
- Page 6 PC Interface for Data Acquisition & Datalogging Features Data Acquisition Models 380801 and 380803 can be connected to a PC where readings can be logged in real-time as they are taken. Transferred reading data can be viewed, plotted, statistically analyzed, printed, saved, and imported in spreadsheet, database, word processing, and other software programs.
