FEATURES Large LCD display 68 x 34 mm ( 1.338 " x 2.677 " ) True measurement of speaker systems actual impedance at 1kHz Three test ranges allow testing of home theater and commercial sound systems Measures transformer impedances Battery operation Low battery indication Data hold function 0 Ohm adjustment EN 61010-1 CAT III 200V, EN 61326-1, EN 61326-2-1, EN 61326-2-2 It is recommended a drawing be first made of speaker system to verify proper installation Take care to ensure that the system is not connected to the amplifier Ensure the system under test is not live Check batery, of sysmbol appears on the display, replace with new batteries Short the tips of the leads, adjust the " 0 Ohm ADJ " , control to set the reading of zero Connect test leads to speaker or speaker leads. Note : Speakers may be connected together either in series or parallel to achieve desired final impedance Rotate the function switch to a suitable range then press the push button to test and take the reading SPECIFICATIONS Measuring Ranges 0-20 Ohm/ 0-200 Ohm/ 0-2k Ohm Test Frequency 1k Hz Accuracy 20 Ohm : + / - 2% rdg + / - 2 dgt or + / - 0.1 Ohm which is greater 200 Ohm/ 2k Ohm : + / - 2% rdg + / - 2 dgt Low Battery Indication Symbol appears on the display Data Hold Indication Symbol appears on the display Display LCD 3-1/ 2 digit ( 2000 counts) Dimensions 175 ( L) x 85 ( W) x 75 ( D) mm Weight Approx. 600g ( battery included) Power Source 1.5V SUM-3 ( AA) x 8 or equivalent Accessores Test leads, carrying case, instruction manual, batteries
