- 4 or F4 ............... key for selecting channel (1=L1, 2=L2, 3=L3) for which statistical values are
shown. Channel can be changed also during running logging and don’t require
recalculation for getting actual statistical values. Some quantities (frequency)
are not measured as three-phase quantities therefore channel is not shown for
them.
- 5 or F5 ............... key for entering “HISTORY VALUES” window in which all measured values are
available.

Remarks / known issues:
• Selection of quantities is not available (all measured quantities are always logged)
• Integration time cannot be changed and is always same as Time Base value
• Obtaining of historical values using command SYST:HIST:GET? maybe not fully functional in fw 7.00 for all
quantities
