Notes on using this Grading Scale
When grading a piece of equipment, the following should
be kept in mind.
- The main objective of of this rating approach is to improve
equipment-grading reliability and provide consistency of results.
- The definitions used do not attempt to change the common meaning of the terms. Instead,
the standards provide criteria for making judgments and deciding which grade
category matches the target equipment.
Equipments' rating is be based solely upon what can
be seen and learned of the equipment through a visual and hands-on
inspection, including powering-up the equipment (if applicable), and
determining whether all originally specified functions and features, as given
in the manufacturer’s specifications, are working properly and satisfactorily.
These ratings are only concerned with
equipment condition. Ratings are not based upon
the perceived value or age of the equipment. A totally useless piece of
equipment might have a graded EXCELLENT (A), and a highly sophisticated,
current production item might have a BAD (D-) grading. Also, the
chronological age of equipment does not affect its grading. Even if a piece
of equipment is totally obsolete, it could have an VERY GOOD (B+) rating.
Equipment is rated using the
manufacturer’s specifications. The
rater uses his experience and common sense to make any judgments relative to
manufacturer’s published specifications.
Modified equipment is eligible for all grade
categories except NEW (A+) and EXCELLENT (A). Generally speaking,
professionally done equipment modifications, enhancing the equipment's usefulness
and/or performance, will not reduce the rating. Modifications that
collectively and/or individually detract from the usefulness and/or
performance of the equipment can lower the rating.
The addition of a manufacturer’s (or third party
manufactured) accessory to equipment is not considered a modification, since
the manufacturer intended that certain accessories be used with the equipment.
For example, the addition of a filter to a receiver, using a filter designed
for the receiver, should not considered a modification of the receiver.
The a fully serviceable user’s manual or other
suitable user-documentation, often including user’s instructions, schematics,
and other technical information, usually has a unique part number, and is part
the equipment. If it is missing, the equipment is incomplete and the rating of
the equipment will be lowered, in some cases. NEW (A+) and EXCELLENT
(A) equipment should
always have a proper
ORIGINAL manual; equipment that is VERY GOOD (B+) or GOOD (B) should have a complete, readable manual. This
requirement does not apply if the manufacturer did not originally provide a
manual or other suitable user-documentation with the newly delivered
equipment.
Interconnecting cables, originally furnished by the
manufacturer, also are part of the equipment. If manufacturer-supplied
interconnecting cables are missing, the equipment is incomplete and the rating
of the equipment might be lowered in some cases.. This means that, to be rated as
VERY GOOD (B) or
higher, a complete set of interconnecting cables should accompany the
equipment, if normally supplied by the manufacturer when originally sold.
If equipment has been used and/or stored in a
"smoking" environment, and has detectable tobacco or other smoke-particle
residue inside and/or outside of the equipment, its rating should be lowered.
NEW (A+), EXCELLENT (A) or VERY GOOD (B+) rated
equipment must not have any detectable smoke residue. ANY detectable smoke
residue limits equipment grade to no higher than GOOD (B).
