Sampling
check box.
Channel Name : You can name the channel. Use up to 16 alphanumeric characters.
Edge : Select whether the count is incremented at rising (UP) or falling (DOWN)
edges of pulses.
Divide Rate
: Select the division rate from 1/1 to 1/255. This setting will be reflected to
SLOPE in the header file.
Count Type : Select gate mode or total mode. If gate mode, specify the gate period by
selecting a multiplier.

Specifications
Number of channels : 2
Input format : Insulated by photocoupler
Input voltage range : 4—10 V/8—24 V (8 mA or more input current required)
Responsive frequency : 2 MHz max.
Sampling frequency : 1 Hz to 200 kHz
Counting method : Division rate: 1/1 to 1/255
Count: 0 to 32767 (16 bits with a sign)
Gate mode: repeats counting pulses within each gate period.
Gate period is specified by the sampling period multiplied by 1 to
255. The output keeps the same count until the next gate. The
count keeps 32767 when overflows.
Total mode: counts total number of pulses from recording start to stop.
Outputs the current total number of pulses during measuring.
Restarts from 0 when overflows.
Counting accuracy: Gate mode: ±5 counts
Total mode: ±1 count
Input connector : Insulated BNC
