Filter
Anti-Noise Filter
The integral time and types of filters applied vary depending on the measurement
interval.
For information on filters, see section 2.9, “Measures Against Noise on the MW100 Data
Acquisition Unit.”
Chattering Filter
Removes chattering of up to 5 ms (can be turned ON/OFF on individual channels)
Turn the chattering filter OFF when measuring on circuits with no chattering.
Integration
The measured values from the 10-CH Pulse Input Module are reset every measurement
intervals by the pulse integral value of each measurement interval. Continued pulse
integration is carried out with the pulse integration (TLOG.PSUM) by the MW100 main
module’s integration function.
Even if the MATH function (/M1 option) is not included, channels included on the 10-CH
Pulse Input Module are only available for integration (TLOG.PSUM).
