Cutoff frequencies : 1, 3, 10, 30, 100 Hz and FLAT (6 steps)
Amplitude ratio at cutoff point : -3 ±1 dB
Attenuation : (-12 ±1) dB/oct.
HPF
Cutoff frequencies : 0.2 Hz
Attenuation : Within (-6 ±1) dB/oct.
AD Converter
16 bits
TEDS
Reads information from TEDS-installed sensors.
Isolation
Between input and case (output): Withstand voltage 500 VDC,1 min.
Between channels: Withstand voltage 500 VDC,1 min.
Standard Accessories
Conversion adapter FV-2A × 4
Optional Accessories
Monitor output cable U-64
Note
If the transducer with a remote-sensing function, a 4-conductor extension cable (N-81 to N-85) enables measurement.
But the remote-sensing function will be ineffective.
