Installation
APx517 B Series Acoustic Analyzer: Installation 19
cessfully installed, connect one end of the USB cable to a
USB 2.0 port on the PC, and the other end to the PC
INTERFACE port on the rear of the APx517. We strongly
recommend that you use the USB cable included with your
instrument (AP part number CAB-APSI). We have tested
other USB cables that perform poorly.
Note: Some PCs have optional USB ports on the
front of the PC, or on extension brackets on the
rear. In many cases these convenience ports
have compromised performance due to the extra
cable length within the PC. We recommend using
USB ports directly connected to the PC mother-
board, typically at the rear of the PC.
Connect the APx517 mains power cord to the instrument
and to a source of ac mains power. See the Mains Power
and Fusing section that follows for more information about
mains connections.
Turn the instrument on by rocking the mains power switch
to ON ( | ). The mains power switch is located in the power
entry module on the rear of the APx517. Windows will
detect the presence of the APx517 on the USB port and will
open the Hardware Update Wizard to search for the correct
software driver. Select “Install the software automatically.”
Windows will find the Audio Precision driver software
installed with APx500 and connect to the APx517.
Launch APx500 by double-clicking on the installed short-
cut. With the APx517 connected, you may be asked to
update the instrument firmware during the first launch of
the measurement software. APx500 will start, and in a short
time you will be presented with the opening screen. Refer to
the APx500 User’s Manual for more information about
making measurements.
The APx500 User’s Manual is available as a PDF
on the APx500 Application Disc and online at
ap.com; a hard-copy version can be ordered from
Audio Precision or your local distributor.
Mains Power and Fusing
Connect the APx517 mains power cord to the instrument
and to a source of ac mains power. Turn the APx517 on by
rocking the mains power switch to ON ( | ). The mains
power switch is located in the power entry module on the
rear of the analyzer.
Connecting your instrument to the electrical
mains supply
A n APx517 must be connected to a 50–60 Hz alternating
current (ac) electrical mains supply. The minimum voltage
is 100 Vac; maximum voltage is 240 Vac. Use only ade-
quately rated detachable mains power cords.
The analyzer is fitted with a universal power supply that
does not require voltage configuration or change of fuse
type to accept mains voltages within the specified range.
Removing and installing mains fuses
For all rated voltages, use two mains fuses of type
• 4 A T/SB (5 x 20 mm) 250 V.
Use only certified fuses of the appropriate specifications.
To remove the mains fuse carrier module, refer to the fig-
ures below and proceed as follows:
