Appendix A: Specifications
The performance limits in this specification are valid with the following conditions:
H This instrument must have been calibrated/adjusted at an ambient temperature between
+20° C and +30° C.
H The instrument must be in an environment with temperature, altitude, humidity, and
vibration within the operating limits described in Table A-14 on page A-29.
H The instrument must have had a warm-up period of at least 20 minutes.
H The instrument must have had its signal-path-compensation routine last executed after
at least a 20 minute warm-up period at an ambient temperature within ±5° C of the
current ambient temperature.
Any conditions that are unique to a particular characteristic are expressly stated as part of
that characteristic.
