  • Page 4: Theory Of Operation

    3. Theory of Operation A magnetic field, proportional to the magnitude of current, surrounds all current carrying conductors. In an AC circuit, the magnetic field will induce a current in the jaws of a clamp-on current probe when the jaws are closed around the conductor. If both conductors of the circuit are enclosed by the jaws of the probe, the magnetic fields will cancel and no measurement is possible.
  • Page 5 (3) Place the jaws of the clamp-on current probe through the X1 section of the separator. The current being drawn by the appliance can then be read directly from the indicator of the clamp-on probe. (4)If the current reading obtained in step 3 is less than one-tenth of the full scale range of the clamp- on current probe and difficult to read, place the jaws of the probe through the X10 section.

    Voltage jacks Outlet Appliance plug Clamp meter 5. Interpretation of Results (1) Most appliance manufacturers state the rating of an appliance on the frame, or housing. The rating will be stated either in AMPERES or WATTS. (2) If the rating is stated in AMPERES then this figure may be compared with the reading on the clamp- on current probe.
  • Page 7 The line voltage may be easily checked by inserting the test probes of an AC voltmeter into the VOLT CHECK input jacks on the separator. (3) If the appliance rating is stated in WATTS, then multiply the reading in current (taken directly from the clamp-on probe) times the line voltage.
