10 Automated Measurement of Waveform
Parameters
The DL850E/DL850EV can automatically measure various parameters of the displayed waveform, such as the
maximum and minimum values. It can also compute statistics for the automatically measured data.
Mode Settings (Mode)
The following types of statistical processing are available for the automatically measured values of waveform
parameters.
• OFF: Automated measurement is not performed.
•
Automated measurement of waveform parameters (ON)
: Automated measurement is performed.
•
Normal statistical processing (Statistics)
: Normal statistical processing is performed.
•
Cyclic statistical processing (Cycle Statistics)
: Statistical processing is performed for each period (cyclic
statistical processing).
•
Statistical processing of history waveforms (History Statistics)
: Statistical processing is performed on history
waveforms.
Automated Measurement of Waveform Parameters (ON)
The DL850E/DL850EV automatically measures the specified measurement items on the source waveform.
Measurement Items (Measure Setup)
Measurement Source Waveform (Trace)
Set the measurement source waveform to one of the waveforms below.
CH1 to CH16,
1
16chVOLT,
2
16chTEMP/VOLT,
2
CAN,
3
LIN,
3
Math1 to Math8, XY1 to XY8
1 You can select the channel of an installed module. Logic module channels are valid only for Frequency, Pulse,
AvgFreq, Period, and Duty parameter measurements.
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.
Measurement Item (Item)
You can choose from the 28 measurement items and delay measurement items listed below. The DL850E/
DL850EV can store a total of up to 64000 data values for all waveforms (CH1 through CH16, 16chVOLT,
16chTEMP/VOLT, CAN, LIN, and Math1 to Math8). A total of up to 32 measurement items can be displayed on
the screen.
