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)

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

·         Threshold: Approx. + 2.5 V (Hysteresis: Approx. 0.5V (2.5V to 3V))


Output signal: Open collector (pull-up to 5V by 10kΩ resistor)

·         Voltage: Max. 30V

·         Current: Max. 0.5A

·         Collector dissipation: Max. 0.2W


Minimum interval varies by number of channels used.


Output port can be specified in each input channel.


4GB SD memory card is installed to slot 1 as standard accessory.


Size of the capture data will be limited to 1/3 of available memory.


Display mode is switched every time the dedicated key is pressed. In magnified digital value mode, the displayed channel number can be specified. In the waveform display mode, the changing of the time scale will be effective from the point of the next displayed data.


Rating under maximum power consumption using the AC adapter, with LCD display on, and battery pack being


Excludes AC adapter and battery pack.
