Redback® Q 2004
Impedance Meter
SYSTEM CHECK MODE
System Check Mode is included for audible testing of larger speaker installations. It allows the Q 2004 to run at full output
for a period of either 20 minutes, 60 minutes or continually (refer to the Menu options), so the installer can walk around the
install to check sound is present on all speakers.
To activate this mode connect the test leads to the load to be checked, ensure that an amplifier is not connected. Make sure
the Q 2004 is OFF then press the “TEST” button and hold for 5 seconds. “SYSTEM CHECK” will display on the LCD and a
1kHz tone will be put out the test leads.
The unit will stay in “System Check Mode” until the time elapses, the “TEST” button is pressed or the battery runs flat.
SWITCHING OFF
To switch off the Q 2004 all you need to do is press the “TEST” button again. The LCD will display “POWER OFF” for a
short time then the unit will power down. The Q 2004 is also equipped with an auto power off function. The unit will
automatically power down after a period of 20 seconds in Single test mode and 30 minutes in System check mode, saving
precious battery life.
BATTERY CHARGING
“LOW BATTERY” will display on the LCD when the battery
requires recharging.
To recharge the internal battery connect the supplied USB
lead to a 5VDC USB source and connect the other end to the
charging socket located on the top of the Q 2004.
(Replacement/and or extra lead Altronics part # P 6703)
“CHARGING” will display on the LCD along with the charge
status. When the battery is charged, the unit will stop
charging and display “CHARGE FINISHED” on the LCD. The
charger can then be unplugged. The inbuilt charging circuit
is a slow charger and will take up to 12 hours to charge a
completely flat battery.
NOTE:
1) The Q 2004 will not function as an Impedance meter when charging.
2) The charger can be removed at any time during charging though battery life will suffer.
3) The Q 2004 will still function when “LOW BATTERY” is being shown on the LCD but the measured results may be out by
as much as 10%.
