Safety Information
Do NOT service or repair this equipment unless properly
qualified. Servicing should be performed only by a quali-
fied technician or an authorized Audio Precision distributor.
Do NOT defeat the safety ground connection. This equip-
ment is designed to operate only with an approved three-
conductor power cord and safety grounding. Loss of the
protective grounding connection can result in electrical
shock hazard from the accessible conductive surfaces of this
equipment.
Do NOT exceed mains voltage ratings. This equipment is
designed to operate only from a 50–60 Hz ac mains power
source at 100–240 Vac nominal voltage. The mains supply
voltage is not to exceed ±10 % of nominal (90–264 Vac).
For continued fire hazard protection, fuses should be
replaced ONLY with the exact value and type indicated on
the rear panel of the instrument and discussed on page 19 of
this booklet.
The International Electrotechnical Commission
(IEC 1010-1) requires that measuring circuit terminals used
for voltage or current measurement be marked to indicate
their Measurement Category. The Measurement Category is
based on the amplitude of transient or impulse voltage that
can be expected from the AC power distribution network.
This product is classified as Measurement Category I,
abbreviated “CAT I”. This product should not be used
within Categories II, III, or IV. The APx517 measurement
terminals are intended to be used for the measurement of
audio signals only.
Do NOT substitute parts or make any modifications with-
out the written approval of Audio Precision. Doing so may
