7. Depending on the displayed results, follow the instructions in the table.
result interpretation instructions
OK
measured impedance is within expected range enclosure is in working order electrically
?
unsupported preset family only supported enclosures should be tested
NC
Not Connected if cables are connected:
1. inspect the cables and connections
2. go to step 8 (p.37)
NOK
measured impedance is not within expected range
UNDEF
measured impedance is undefined
1. check that all the prerequisites are met, in
particular that the loaded preset corresponds
to the connected speaker's family
2. inspect the cables and connections
3. go to step 8 (p.37)
8. Under NC, NOK and UNDEF results, press and hold the corresponding OUT key.
The amplified controller displays:
— the tested frequencies,
— information on the measured impedance:
— OPEN for open circuit (found in NC results),
— SHORT for short circuit (found in NOK results), or
— a percentage of variation from the expected range (found in NOK and UNDEF results)
— the number of operational transducers out of the total
Low variations from the expected range are acceptable: displayed percentage can be different from 0 and all
transducers considered operational.
