Set the length (number of divisions) to record each time data is acquired. Each division of the recording
length consists of 100 data points. The number of data points of the whole recording length is the specified
recording length (divisions) × 100, + 1.
Example. The number of data points when the specified recording length is 50 divisions:
50 div × 100 data points + 1 = 5001 data points
Optical resolution differs with different input units.
The following table shows the full scale optical resolution for all the units.
The smallest optical resolution can be calculated from the screen full scale value and the full scale optical
resolution shown in the table below.
E.g. In the case of measurement with the 8966 Analog unit
The smallest optical resolution when the power voltage with vertical axis 20V/div and vertical axis mag-
nification x 1 is measured is
Screen full scale: 20 V/div x 20 div = 400 V
Full scale optical resolution at vertical axis x 1: 2000
400 V / 2000 = 0.2 V
Brackets indicate valid data range
*: With the 8967 Temp Unit, the valid range differs depending on the thermocouple. For information on the minimum resolution,
see the specifications of the 8967 Temp Unit.
The following shows the speeds of saving binary data (reference values) using different media and inter-
faces. Note that the data saving speed varies depending on the saving conditions, device manufacturer,
device capacity, communication conditions, and others.
