Count mode: 2000LSB/div (f.s. = 20 div)
Except for count mode and power frequency mode: 500LSB/div (f.s. = 20 div)
Power frequency mode: 100LSB/div (f.s. = 20 div)
Response time Within 40 μs + sampling interval of instrument in which the module is installed.
Input voltage range ±10 V, ±20 V, ±50 V, ±100 V, ±200 V, ±400 V
Threshold value ±10 V range: −10 V to +10 V variable (0.1-V step)
±20 V range: −20 V to +20 V variable (0.2-V step)
±50 V range: −50 V to +50 V variable (0.5-V step)
±100 V range: −100 V to +100 V variable (1-V step)
±200 V range: −200 V to +200 V variable (2-V step)
±400 V range: −400 V to +400 V variable (5-V step)
Slope Rising, falling (Frequency, rotation speed, power frequency, count mode)
Level High, Low (Duty ratio mode, pulse width mode)
Hold Frequency mode/Rotation speed mode: ON, OFF (1 Hz, 0.5 Hz, 0.2 Hz, 0.1 Hz)
When OFF is selected: If the next measurement value is not determined within the waiting
time period, the frequency or the rotation speed will be determined
using the value that is calculated based on the time period
between the timing of the last measurement and the timing of the
sampling. If these calculated values are less than the specified
values, then use 0.
Smoothing
OFF, ON (The permissible smoothing frequency is up to 10 kHz.)
(Frequency mode, rotation speed mode)
Low-pass filter OFF, 5, 50, 500, 5 k, 50 kHz
Input coupling
