15.1 Introduction
The on board Data Logger of the USN52 L provides a simple and
reliable way to record thickness readings. Displayed readings are
stored in one or more files by pressing
or optional Remote
Send Switch.
A file is a group of Data Logger memory locations for storing read-
ings, one reading per location, and reporting measurement data.
File size is determined automatically when the operator sets the
desired number of files, up to a maximum of 99. The USN52 L
divides the total memory capacity of 2500 readings by the number
of files specified and creates the maximum number of files, with
an equal number of locations allowed by capacity (see Table 15-1
in Section 15.2).
The first reading is stored in each file starting with location number
1, unless the operator selects a different starting location. The
data logger automatically indexes to the next location and subse-
quent readings are stored sequentially until all locations have been
filled or another location or file is selected to receive readings.
Location numbers and stored readings can be viewed and edited
either from the A-scan display or menu 8 (lower level). Readings in
individual file locations, entire files, or all of memory can be cleared.
Individual readings, the selected file and the entire data logger
memory can be transmitted via the RS-232 interface for docu-
mentation, storage and analysis.
A built-in report format outputs selected file(s) or the entire data
logger memory, file by file, to a PC or compatible serial printer, in a
24-column ASCII format, in the selected language.
As with the instrument control settings, stored readings are retained
indefinitely in memory, even when the batteries are removed.
