The following table describes the information that is stored in each column of the spreadsheet.
Heading
Description
Index
Provides an identifier for each reading.
Current
The value saved in the buffer depends on the measurement function. For more
information, see the following table.
Unit
Indicates the unit of measure for the current reading; value is A (amperes).
Voltage
The value saved in the buffer depends on the measurement function. For more
information, see the following table.
Unit
Indicates the unit of measure for the voltage reading; value is V (volts).
Math
T when Math is on; F when Math is off.
Output
CC (constant current), CV (constant voltage), or OFF. For details, see Constant voltage
(CV) and constant current (CC) mode (on page 2-72).
Date
Date the readings were made.
Time
Time the readings were made.
Fractional
Fractional portion of the timestamp (in seconds) when each reading was made. Fractional
seconds are the fractional part of an absolute timestamp. For example, the fractional part
of the 16:17:21.1923 timestamp is .1923.
The current and voltage values in the buffer are different for the measurement function.
