Reading Format
During a scan, the instrument automatically adds a time stamp to all
readings and stores them in memory. Each reading is stored with
measurement units, time stamp, channel number, and alarm status
information. From the remote interface, you can specify which information
you want returned with the readings. The examples below show a reading
in relative and absolute format with all fields enabled.
Relative Format (Default): 
Absolute Format:
• The reading format applies to all readings being removed from the
instrument from a scan; you cannot set the format on a per- channel
basis.
• The
CONFigure and MEASure? commands automatically turn off the
units, time, channel, and alarm information.
• The format settings are stored in volatile memory and will be lost when
power is turned off or after a Factory Reset (
*RST command).
Remote Interface Operation: Use the following commands to select the
reading format.
