Important: Avoid switching power off to the Super-Thermometer while measurement and recording are
in progress or recorded data may be lost.
Measurements are recorded when the START RECORD (F5) function key in the Measurement screen has
been pressed. The Status Bar at the bottom of the Measurement screen indicates if recording is ON or OFF.
Each recorded measurement includes the date and time of the measurement, channel, measured value, and
unit. Additional statistical data is also recorded when the Record Statistics setting is ON.
The data written into internal memory is organized into data sets and each data set is identied by the date and
time of the rst measurement in the set. A new data set is started each time the START RECORDING (F5)
function key is selected if measurement is on. Likewise, a new data set is started each time the START MEA-
SUREMENT (F1) function key is selected if recording is on.
Data is recorded to the USB le in ASCII text, comma separated values (CSV) format, one measurement per
line. Each line is terminated with a carriage return and linefeed. The format of a line of data when the Record
Statistics setting is OFF is as follows:
<measurement value>,<unit>,<channel number>,<date and time>
Example: 231.927562,C,4,2010-01-10 14:23:10
When RECORD STATISTICS is ON, the format is as follows:
<measurement value>,<unit>,<channel number>,<date and time>,<ratio>,<resistance>,<mean>,<std dev>
Example: 231.927562,C,4,2010-01-10 14:23:10,1.89280433,47.318163,231.927848,0.000231
USB les are written to a folder named “\159x\data” on the USB memory device and have the extension
“.txt”. If the le does not exist, it will be created. If the le already exists, new data will be appended to the
data already in the le. For data to be recorded to external memory, a Linux compatible USB memory device
formatted with a FAT32 le system must be inserted into the USB Connection on the front panel.
The following are the Recording Menu function keys.
5.7.3.4.1 RECORDING SETTINGS (F1)
MAIN MENU | MEASURE MENU | RECORDING MENU |
The Recording Settings function key opens a screen that allows the user to view and change settings related to
measurement recording. The conguration elds in the Recording Settings screen are as follows:
MEMORY DEVICE - allows the user to choose which memory device to be written to. The options are
Internal, USB or Both.
USB FILE - is a user-selectable le name to which data is stored on the USB memory device. Upon pressing
Enter, the Alpha-Numeric Interface opens allowing the user to input a le name. The le name extension “.txt”
is automatically appended to the le name.
RECORD STATISTICS - determines whether statistics data is recorded to the memory device along with the
measurement. Additional data recorded when Record Statistics is ON include Resistance Ratio, Resistance,
Statistical Mean, and Standard Deviation. When Record Statistics is ON, the capacity of the memory device,
in terms of number of measurements, is reduced by about a factor of two.
The function key used to Start and Stop Recording is located in the Measurement Menu, Section 5.6.10,
START/STOP RECORD (F5), on page 28.
5.7.3.4.2 VIEW DATA (F2)
MAIN MENU | MEASURE MENU | RECORDING MENU |
The View Data function key is used to view measurements that have been recorded into internal memory. The
View Data screen displays the list of datasets recorded in memory. The user pages through the datasets using
the Left/Right Arrow Keys and views data in a dataset using the Up/Down Arrow Keys.
