[. . . ] Before beginning all unknown measurements, set meter to highest possible range. Before breaking a circuit for testing, turn off the power to the circuit. When disconnecting from a circuit, disconnect the hot lead first, then the common lead. Disconnect the meter from the circuit before turning off any indicator, including motors, transformers, and solenoids. [. . . ] Using the trigger to open the jaws, fully enclose the conductor within the clamp. If the meter is in auto-ranging mode, the range will be automatically selected. If the meter is in manual ranging mode, press the range button to select the desired range. Measure AC current. 5 6 DC Current Measurements DC Current Range 400A 2000A 2000-2500A Overload Protection: Resolution 0. 1A 1A 1A + 3000A Accuracy ±(1. 5% +3) ±(2. 0% +3) 4.

The analog output of the meter is proportional to the current measurement (1mV/A). Connect the monitoring device to the input terminals of the power clamp meter. Connect these two terminals to an oscilloscope, chart recorder or data logger to observe the wave form, or record the data for future analysis.

Insert the black test lead into the COM terminal and the red test lead into the + terminal. If the meter is in auto-ranging mode, the range will be automatically selected. Insert the black test lead into the COM terminal and the red test lead into the + terminal. If the meter is in auto-ranging mode, the range will be automatically selected. If the meter is in manual ranging mode, press the range button to select the desired range.
