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 |
