    1107 IM   Audio Impedance Tester
    1107 IM
     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 theatre 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
    Measuring Ranges 0-200 Ohm/ 0-2k Ohm/0-20k Ohm
    Test Frequency 1k Hz
    Accuracy 200 Ohm/2k Ohm : +/- 2% rdg +/- 2 dgt
    20K Ohm/2k Ohm : +/- 3% 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
