3.5.6 PERFORMANCE METER (ONLY FOR XWEB500DIN)

The value added by this new software tool is remarkable: possibility to check the correctness of the
compressor rack size; possibility to check the proper functioning of each device; statistics data collection.
Firstly go to "Data" then "Performance meter". Secondly go to "Class" menu and then choose "Create
class". Fill in as the following:
Class Name: the name of the class, usually corresponds to the name of the typology you have already
created.
Typology Filter: let you filter between different typologies.
Set point: let you choose between more than one set point (if available)
Probe: let you choose which probe you want to use to calculate the average temperature.
Sampling (min.): period of time to use for collecting data samples
Avg. Factor: this number will be multiply by the "Sampling" to obtain the average time interval length.
This value is computed to calculate the average value for the interval.
Normal Range (min. and max.): the user can add a temperature interval. When temperature is out of
this range the slide bar will be coloured with red.
Defrost offset (min.): elapsed time to count before starting camputing the maximum temperature
reached after a defrost.
The following picture shows how XWEB computes the maximum value of temperature (Max) and the
maximum value after a defrost (Tdef). The former is computing by subtracting the time interval [A,B]. The
latter depends on the parameter "Defrost Offset", so the system computes Tdef by subtracting the time
interval [A,C].
