Frequency ranges 0.05, 0.1, 0.5, 1,5, 10, 50, 100, 500 Hz/DIV 1, 5 kHz/DIV
5, 10, 50, 100, 500 r/min/DIV
Power source frequency ranges: 50 Hz (40 to 60 Hz), 60 Hz (50 to 70 Hz)
Frequency accuracy ±0.2%f.s.(except 100 kHzf.s. range)
±0.7%f.s.(100 kHzf.s. range)
±0.032Hz(Power source frequency ranges)
Frequency hold ON/OFF (waiting time 10 ms, 1 s variable )
When hold is OFF, the current measurement value is halved if the next
measurement value is not fixed within the waiting time.
Count ranges 5, 10, 50, 100, 500 counts/DIV
1, 5, 10, 50, 100, 500 k counts/DIV
Duty range 100%f.s.
Duty accuracy ±1%(10 Hz to 10 kHz)
Threshold value (common) -10 to +10 V variable(0.2 V steps)
Frequency measurement
ranges (common)
DC to 100 kHz (Frequency)
DC to 90 kHz (Count)
10 Hz to 100 kHz (Duty)
Response time (common) 10μs not greater (Frequency (more than 300 Hz), Count)
50μs not greater (Frequency (300 Hz not greater), Duty)
The sampling period of the MEMORY HiCORDER in which the unit is
installed must be added to the above.
