Basic Specifications
Decimation
(text format only)
Decimate and save Off or a value from 1/2 to 1/100,000 (user-selectable)
-2. Loading data
Loading saved data The user can specify a position and then load up to 256 M data points of previously saved
text-format data (when recording 1 analog channel; if recording n channels, 256 M/ n data
points).

*1: Total, positive, negative, or absolute value (user-selectable)
*2: Threshold values can be set for individual channels.
Calculation range During recording:
Calculations performed for all data during recording
After recording has stopped:
Calculations performed for all data in the internal buffer
memory, or for data in a calculation range specified by
the A/B cursors (on the vertical axis)
Time segmentation
calculations
Enable/disable (user-selectable)
Disabled: Calculations performed for all data during recording
Enabled: Data for each segment of time, starting with the start
of measurement
Segmentation time: Set DD HH:MM format
Waveform
calculations
Calculation content The following calculations can be set:
• Four arithmetic operations* among channels
•Moving average, simple average, integral, and integration of
any channel
Calculated values are recorded as data for the calculation
channels (W1 through W30). (Calculations are performed at
the same time as measurement. Values cannot be recalculated
after measurement.)
