Figure 3- 6 Data Reader
b. DataView
The DataView software for a personal computer is supplied on a floppy disk. This software allows interrogation, configuration variable assignment, screen view of the data, hard copy report generation, cold treatment probe calibration, cold treatment initialization and file management. Refer to Data Retrieval manual
c. Communications Interface Module
The communications interface module is a slave module which allows communication with a master central monitoring station. The module will respond to communication and return information over the main power line.
With a remote monitoring unit installed, all functions and selectable features that are accessible at the unit may be performed at the master station. Retrieval of all DataCORDER reports may also be performed. Refer to the master system technical manual for further information.
d. DataLine
The DataLINE software for a personal computer is supplied on both floppy disks and CD. This software allows interrogation, configuration variable assignment, screen view of the data, hard copy report generation, cold treatment probe calibration and file management. Refer to Data Retrieval manual
3.6.11 USDA Cold Treatment
Sustained cold temperature has been employed as an effective postharvest method for the control of Mediterranean and certain other tropical fruit flies.
Exposing infested fruit to temperatures of 2.2 degrees Celsius (36_F) or below for specific periods results in the mortality of the various stages of this group of insects.
In response to the demand to replace fumigation with this environmentally sound process, Carrier has integrated Cold Treatment capability into its microprocessor system. These units have the ability to maintain supply air temperature within
a. USDA Recording
A special type of recording is used for USDA cold treatment purposes. Cold treatment recording requires three remote temperature probes be placed at prescribed locations in the cargo. Provision is made to connect these probes to the DataCORDER via receptacles located at the rear
The standard DataCORDER report displays the supply and return air temperatures. The cold treatment report displays USDA #1, #2, #3 and the supply and return air temperatures. Cold treatment recording is backed up by a battery so recording can continue if AC power is lost.
b. USDA/ Message Trip Comment
A special feature is incorporated in DataLine/DataView which allows the user to enter a USDA (or other) message in the header of a data report. The maximum message length is 78 characters. Only one message will be recorded per day.
3.6.12 USDA Cold Treatment Procedure
The following is a summary of the steps required to initiate a USDA Cold Treatment.
a. Calibrate the three USDA probes by ice bathing the probes and performing the calibration function with the DataReader, DataView or DataLine. This calibra- tion procedure determines the probe offsets and stores them in the controller for use in generating the cold treatment report. Refer to the Data Retrieval manual
b.
c..Install the DataCORDER module battery pack (if not already installed).
d. Place the three probes. The probes are placed into the pulp of the product (at the locations defined in the fol- lowing table) as the product is loaded.
