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
