13. Frequency 200 ms measurement specications Freq
Measurement method Reciprocal method
Value calculated from the reciprocal of the accumulated time for 20 ms on U1
Displayed items Frequency
Measurement range 70.000 Hz
Measurement accuracy ±0.020 Hz or less
Event threshold Specied in deviation, 0.1 Hz to 9.9 Hz, 0.1 Hz increments
Event IN Starting time of an approximately 200-ms aggregation period to which a value belongs
when it exceeds the positive threshold value or falls below the negative threshold value
Event OUT Starting time of an approximately 200-ms aggregation period to which a frequency
value belongs when it falls below the value calculated by subtracting 0.1 Hz from
the positive threshold value or exceeds the value calculated by adding 0.1 Hz to the
negative threshold value
Equivalent to a frequency hysteresis of 0.1 Hz
