(2)-1 Sampling interval
Sets the sampling interval for data capture.
The table below shows the number of measuring channels and sampling interval values that can be set.
If data fluctuate due to noise, set the sampling interval to a value which enables the digital filter function.
Number of Measuring Channels
*1: "Number of Measuring Channels" is the number of channels in which input settings are NOT set to "OFF".
*2: The temperature setting is not available for sampling intervals of 10, 20, and 50 ms
To use the digital filter function, you must set the AC power supply frequency accurately. Follow the instructions on page 3-28
to ensure that the settings are accurate.
