The period of the specified waveform is applied to all waveforms.
1 You can select the channel of an installed module.
2 When a 16-CH voltage input module or 16-CH temperature/voltage input module is installed. After you
select 16chVOLT or 16chTEMP/VOLT, select a sub channel.
3 On the DL850EV when a CAN bus monitor module or CAN & LIN bus monitor module is installed. After
you select CAN or LIN, select a sub channel. You cannot select waveforms whose data type (Value Type)
is set to Logic.
• Own
A period is determined for each source waveform. However, if signals that have different periods are applied
to multiple channels, the number of iterations of automated measurement and statistical processing for each
signal is equal to the number of periods in the slowest signal.
CH2
CH1
The number of cycles in the channel with the slowest cycle (CH3)
is four, so statistical processing is performed on the four oldest
cycles of the data for CH1 and CH2. The remaining data is not
used for statistical processing.

Statistically processed cycles
Statistically processed cycles
Statistically processed cycles
Statistical processing is performed in periods that are determined in order from the oldest data of the
displayed waveform. It cannot be used at the same time as 1-cycle mode.
Execution of Measurement (Execute Measure)
Executes statistical processing. You can select Execute Measure when Mode is set to Cycle Statistics or History
Statistics.
Press Abort to stop statistical processing.
• The number of cycles being used for the cyclic statistical processing is displayed in the statistical display’s
Count column.
• The number of cycles that can be used in cyclic statistical processing varies depending on the number of
measured items that the DL850E/DL850EV is calculating the statistics of.
64000/(the number of measured items that the DL850E/DL850EV is calculating the statistics of)
• If the sample rates of the cycle trace and the displayed waveform are different, the displayed waveform will
not be measured. The measured value and statistical processing value are both displayed as ‘*****.’
