Meas. Functions (MR-PRO only)
Impedance Test
The impedance test supports the verifications of distributed
loudspeaker installations and shows detailed information of
the connected load.
Connect any unpowered load between Pin 2 and 3 of the XLR
output for best performance.
Damage caused by high voltage
Never connect the instrument to a power
output or any activated distribution system!
MR-PRO 70V/100V Protection
Protects the Minirator MR-PRO against ac-
cidentally applied 70V/100V voltages during
impedance or power testing at distributed
speaker systems.

In the mode |Z| + Phase 1 the absolute value of the imped-
ance and the phase is shown.
Based on the measured impedance, the apparent power 2
which the load would sink when driven with a defined refer-
ence voltage is calculated and displayed.
