HOW TO USE
- It is recommended a drawing be first made of the 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 battery, if “ “ symbol appears on the display, replace with new batteries.
- Short the tips of the leads, adjust the “0Ω.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. - Rotary the function switch to suitable range then press the push button to test and take the reading.Example : Measure system power-an 10W up (1106 IM)
P=ZI2
P=V2 / Z
For example on a 100V system : If P = 50W Z = V2 / P = 1002 / 50 = 200Ω
(1) The tester can measure load down to 2kΩ. (5W at 100V line).
(2) The tester can’t measure 100V system with power lower than 5W. - Checking a speaker :
Speakers are general from 2 to 16Ω, use 20Ω range or for higher impedance speaker, use 200Ω or 2kΩ range.
