Characteristics Tables
The tables use the following abbreviations:
Performance Requirement (Req).
All performance requirements in the specifica-
tion tables are identified with
Req
, and can be assured by completing the
Performance Check Procedure located in the service manual. Allow a warm-up
time of 20 minutes.
Performance requirements in the electrical specifications are valid over an
ambient temperature range of +20
°
C to +30
°
C. The Performance Requirement
tolerances listed in the Electrical Specification are doubled over the temperature
range of 0
°
C to +40
°
C, unless otherwise specified. Test equipment used to
verify Performance Requirements must be calibrated and working within the
limits specified in the service manual Equipment Required List.
