The following table describes the information that is stored in each column of the spreadsheet. 
Provides an identifier for each reading. 
The value saved in the buffer depends on the measurement function. For more 
information, see the following table. 
Indicates the unit of measure for the current reading; value is A (amperes). 
The value saved in the buffer depends on the measurement function. For more 
information, see the following table. 
Indicates the unit of measure for the voltage reading; value is V (volts). 
T when Math is on; F when Math is off. 
CC (constant current), CV (constant voltage), or OFF. For details, see Constant voltage 
(CV) and constant current (CC) mode (on page 2-72). 
Date the readings were made. 
Time the readings were made. 
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.
