3.1 steady state steadystate
Within the chamber workspace all measuring points parameters change chamber volume to achieve performance requirements of their own
status.
3.2 indicating instrument indication error indicatedvalueerrorofindicatedmeter
Chamber in stable condition, within the specified time, the chamber indicator represents the arithmetic mean value and
All measurement points measured value difference arithmetic average of the test chamber within the workspace.
Rate of temperature change 3.3 temperaturevariationrate
Within a predetermined temperature range, the working chamber of a predetermined point in space temperature monotonic rise (or fall)
When the total amount of temperature change in the ratio of process time experience. There are three different rate of temperature change of the definition, i.e.,
The maximum average rate of temperature change, the whole average rate of temperature change and transient rate of temperature change with ℃/min represents.
3.4 acceleration amplitude indication error indicatedvalueerrorofaccelerationamplitude
