Measurement accuracy is specified according to the measurement range and input pulse width
[Definition of measurement accuracy]
±(0.05% of 10 div + accuracy dependent on the input pulse width)
[Accuracy dependent on the input pulse width]
Input pulse width of 500 µs or greater: 0.05% of the input pulse width
Input pulse width of 20 µs to 500 µs: 0.1% of the input pulse width + 0.1 µs
Input pulse width of 10 µs to 20 µs: 0.2% of the input pulse width + 0.1 µs
Input pulse width of 10 µs or less: 0.5% of the input pulse width + 0.1 µs
Input voltage range (±FS) When using 1:1 probe attenuation: ±1 V, ±2 V, ±5 V, ±10 V, ±20 V, ±50 V (±FS)
Input impedance 1 MΩ ± 1 approx. 35 pF
Pull-up function:  10 kΩ, approx. 5 V (pull-up can be turned ON only when the input 
is set to Pull-up 5 V)
Input coupling settings AC, DC
Probe attenuation setting 10:1, 1:1
Minimum voltage width for pulse 
detection
200 mV
P-P
Bandwidth limit Select from Full, 100 kHz, 10 kHz, 1 kHz, and 100 Hz
Cutoff characteristics: −12 dB/OCT (typical value
9
)
Threshold Set within the FS of the voltage range. Set in units of 1% of the FS.
Hysteresis Select ±1%, ±2.5%, or ±5% of the FS of the voltage range
Preset function Logic (5 V/3 V/12 V/24 V), electromagnetic pickup, zero crossing, pull-up, AC100 V, AC200 V, 
and user-defined
Slope selection Select rising or falling
Lower −3 dB point when AC 
coupled
0.5 Hz or less (0.05 Hz or less when using the 700929 or 702902, 0.005 Hz or less when 
using the 701947) (typical value
9
)
Chatter elimination function OFF or 1 to 1000 ms (1 ms resolution)
Eliminates the chatter that occurs such when the contact input is turned ON/OFF. 
Can discard the signal changes over the specified interval.
Input status indication function Input status indication through the LEDs of each channel function 
When in operation: Illuminates in green when pulse input is detected
When overdriven: Illuminates in red when the input voltage exceeds the range
Compatible probes/cables Connection cable (1:1): Recommended 1
