RCF S.p.A. would like to thank you for purchasing this product, which has
been designed to guarantee reliability and high performance.
FEATURES
1
Impedance measurement (frequency: 1 kHz) of a loudspeaker or a system.
2
Three ranges (20 Ω, 200 Ω, 2000 Ω) that allow to test, for instance, home theatre
systems and / or commercial sound systems.
3
Portable instrument operating with batteries.
4
Low battery indication.
5
Data hold function.
6
Testing auto-off (1 kHz signal) after 20 seconds (but LOCK function).
7
Auto power off after 15 minutes of non-use.
USE
1
TEST
button
It turns on/off the impedance test (when the tester is switched on).
After pressing the TEST button, the load impedance is tested (through a 1 kHz
signal) and the red LED (8) gets lit.
Press again to stop the impedance test (the red LED turns off).
About 20 seconds later (since the activation), the unit automatically quits the
impedance test (but the case the LOCK button has been pressed too).
2
LOCK
button
If the LOCK button is sequentially pressed after the TEST button, the unit will
not quit the impedance test mode automatically (after 20 seconds), but it will be
necessary to press the TEST button again (to turn the impedance test off).
3
HOLD
button
If pressed, the present reading is hold on the display (until the HOLD button is
pressed again). The display H letter indicates the HOLD mode.
4
Display back light button If pressed, the display will be backlit for 10 seconds, in
order to allow the reading even in the darkness.
5
FUNCTION
selector
It turns the unit on/off and allows to choose the desired range (20 Ω, 200 Ω, 2000 Ω).
6
COM
input for the black test lead.
7
Ω
