Number of analog input channels 20 ch, Expandable up to 200 ch by unit of 20 ch External input output Input *1 Trigger or Sampling input 1ch, Logic or Pulse input 4 ch Output *1 Alarm output 4 ch Sampling interval 10 ms to 1 h (in 10 ms to 50 ms, voltage only and limite d channel), External Time scale 1 sec to 24 hour/division Trigger function Action Start or stop capturing data by the trigger Source Start: Off, Input signal, Alarm, External *1, Clock, Week or Time Stop: Off, Input signal, Alarm, External *1, Clock, Week or Time Combination OR or AND condition at the level of signal or edge of signal Condition Analog: Rising, Falling, Window-in, Window-out Pulse: Rising, Falling, Window-in, Window-out Logic: Rising, Falling Alarm function Detecting method Level or edge of signal Condition Analog: Rising, Falling, Window-in, Window-out Pulse: Rising, Falling, Window-in, Window-out Logic: Rising, Falling Alarm output *1 4 channels, Output type: Open collector (pulled-up to 5 V by res istor 10 kΩ) Pulse input function *1 Accumulating count mode Accumulating the number of pulse s from the start of measurement Range: 50, 500, 5k, 50k, 500k, 5M, 50M, 500M counts/F.S. Instant count mode Counting the number of pulses per sampling interval Range: 50, 500, 5k, 50k, 500k, 5M, 50M, 500M counts/F.S. Rotation count (RPM) mode Counting the number of pulses per second and the n it is converted to RPM Range: 50, 500, 5k, 50k, 500k, 5M, 50M, 500M rpm /F.S. Max. input pulse rate 50k pulses/sec or 50k counts per sampling interval (16 b its counter is used) Calculation function Between channels Addition, Subtraction, Multiplic ation and Division for analog input Statistical Select two calculations from Average, Peak, Max., Min., RMS Search function Search for analog signal levels, values of logic or pulse or ala rm point in captured data Interface to PC Ethernet (10 BASE-T/100 BASE-TX), USB (Full speed) Storage device Built-in Flash memory (2 giga-bytes), USB memory device *2 Data saving function Captured data Direct saving of data into built-in Flas h memory or USB memory device Others Setting conditions, Screen copy Ring capturing mode Function: ON/OFF, Number of capturing point: 1000 to 200 0000 (size of the capture data will be limited to 1/3 of available memory when i n Ring Mode) USB memory device emulation USB Memory emulation mode (Transfer or delete th e file in built-in memory) Engineering scale function Set based on the reference point of the scaled o utput and input signal for each channel (Voltage measurement: four points are ne cessary to scale the output, Temperature measurement: two points are necessary t o scale the output).
