GL240 Specifications


Number of analog input channels

10 channels

External input/
output *1

Input *2

Trigger or Sampling (1 channel), Logic/Pulse (4 channels)

Output *3

Alarm (4 channels)

Sampling interval

10 ms to 1 hour (10ms to 50ms: voltage only) *4, External signal

Time scale of waveform display

1sec. to 24 hour /division

Alarm function

Trigger action

Start or stop capturing data by the trigger

Repeat action

Off, On (auto rearmed)

Trigger source

Start: Off, Measured signal, Alarm, External, Clock, Week or Time
Stop: Off, Measured signal, Alarm, External, Clock, Week or Time

Condition Setting

Combination: OR or AND
Analog signal: Rising (High), Falling (Low), Window-in, Window-out
Logic signal: Pattern (combination of each input signal in high or low)
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

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)


Between channels

Addition, Subtraction, Multiplication, and Division for analog input


Select two calculations from Average, Peak, Maximum, Minimum, RMS

Search function

Search for analog signal levels, values of logic or pulse or alarm point
in captured data

Interface to PC

USB (Hi-speed), WLAN (using B-568 option)



SD memory card (Support SDHC, up to 32 GB), supports 2 slots *6

Saved contents

Captured data, Setting conditions, Screen copy

Capturing mode

Mode: Normal, Ring, Relay
Ring: Saves most recent data (Number of captured data: 1000 to 2000000 points) *7
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 BGD or CSV format)

Scaling (Engineering unit) function

Measured value can be converted to the specified engineering unit
• Analog 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 parst data (using dual display mode (Current + Past data))
• Hot-swapping the SD memory card
• Saving data in between cursors
