Pulse (number of count): Rising (High), Falling (Low), Window-in, Window-out
Alarm output Outputs a signal when alarm condition occurs in the input signal *5
Pulse input function
Rotation count
Counts the number of pulses per sampling interval and converts to rpm
(rotations per minute), Number of pulses for one rotation may be set to
50, 500, 5000, 50k, 500k, 5M, 50M, 500M rpm/F.S. (rpm./Full Scale)
Accumulates the number of pulses from the start of measurement
50, 500, 5000, 50k, 500k, 5M, 50M, 500M C/F.S. (Counts/Full Scale)
Instant count Counts the number of pulses per sampling interval
50, 500, 5000, 50k, 500k, 5M, 50M, 500M C/F.S. (Counts/Full Scale)
Maximum number of pulse inputs Maximum input frequency : 50kHz
Maximum number of count : 50kC/sampling (16-bit counter)
Calculation function
Between channels Addition, Subtraction, Multiplication, and Division for analogue input
Statistical Select two calculations from Average, Peak, Maximum, Minimum, RMS
Search function
Search for analogue signal levels, values of logic or pulse or alarm point
in captured data
Interface to PC USB (Hi-speed), WLAN (using B-568 option)
Storage device
Internal Built-in 4GB Flash Memory *6
External One SD card slot (Support SDHC memory card, up to 32GB) *7
Saved contents Captured data, Setting conditions, Screen copy
Back up recording data function
Backup interval *8 Off, 1, 2, 6, 12, 24 hour(s)
Backup file destination *8 SD memory card or FTP server
Data format *8 GBD (binary) or CSV (test)
Check-sum function (Verifies data file) OFF: Not adding check-sum code to data file.
ON: Adding check-sum code to data file. Check-sum code is verified when replaying data on the GL unit or GL-Connection software.
Capturing mode Mode: Normal, Ring, Relay
Ring: Saves most recent data (Number of captured data: 1000 to 2000000 points) *9
Relay: Saves data to multiple files without losing data until data capturing is stopped
Replay Data Replays captured data that was saved in the GL240 (in GBD or CSV format)
Scaling (Engineering unit) function Measured value can be converted to the specified engineering unit
• Analogue voltage: Converts using four reference points (gain, offset)
• Temperature: Converts using two reference points (offset)
• Pulse count: Converts using two reference points (gain)
Action during data capture • Displaying past data (using dual display mode (Current + Past data))
• Hot-swapping the SD memory card
• Saving data in between cursors
