History Waveform Search Mode (Search Mode)
When waveform acquisition is stopped, you can search for history waveforms that meet the specified conditions.
• OFF: Searching is not performed. All history waveforms are displayed.
• Zone: The DL850E/DL850EV searches for history waveforms that did or did not pass through a specified
search zone.
• Parameter: The DL850E/DL850EV searches for history waveforms that do or do not meet specified search
parameter conditions.
Search Condition Settings for Zone Searching (Search Setup)
Search Zone (Select Zone)
You can register four search zones to Zone1 to Zone4. For each search zone, set the channels to search, the
search condition, and the search range.
Search Condition (Condition)
• IN: The DL850E/DL850EV searches for waveforms that pass through the specified search window.
• OUT: The DL850E/DL850EV searches for waveforms that do not pass through the specified search window.
• OFF: The DL850E/DL850EV does not search for waveforms.
Source Waveforms (Source)
The DL850E/DL850EV searches through the waveforms that you select for Source. You can select waveforms
from CH1 to CH16. The waveforms of channels that have not been specified as search source channels are also
displayed. However, you cannot search through the waveforms of a logic module, 16-CH voltage input module,
16-CH temperature/voltage input module, CAN bus monitor module, or CAN & LIN bus monitor module.
Search Window Upper and Lower Limits (Upper and Lower)
You can set the limits within ±5 div. You can set them in 0.01 div steps.
You cannot set the upper limit to a value that is less than the lower limit.
Left and Right Sides of the Search Window (Left and Right)
You can set the left and right sides within the range of ±5 div. The resolution is 10 div/display record length.
You cannot set the left side to a value that is greater than the right side.
Search Logic (Logic)
• AND: The DL850E/DL850EV searches for waveforms that meet all the search conditions specified for Zone1
to Zone4.
• OR: The DL850E/DL850EV searches for waveforms that meet at least one of the search conditions specified
for Zone1 to Zone4.
