GL2000
midi Logger

High speed 1 MS/s simultaneous sampling with isolated input

Simultaneous sampling

GL2000 utilizes simultaneous sampling to eliminate slowdown in sampling rate by using multiple A/D converters in simultaneous sampling method. Four individual A/D converters in each channel sustains the maximum sampling speed for all four channels to measure high speed rapid voltage fluctuation and multi-channel vibration measurement.
Sampling interval: 1 µs to 1 min (in steps of 1, 2, 5)

External sampling function

Sampling of the logger is performed in sync with an external device using an external signal input.
Maximum input frequency: 100 kHz    * B-513 Input/Output cable for GL is required.

CAT III 600 V is compatible with measuring power supply circuit in an equipment that captures power directly from the distribution panel.

Measures abnormalities in a repeated waveform by effectively measuring the corresponding RMS value

• In 1000 Vrms range, Crest Factor is up to 1.41
  * Maximum rated safety voltage: 600 V rms, Peak voltage: 850V
• In other range, Crest Factor is up to 2.0

Scaling (Engineering unit) function

Measured voltage value can be converted to a specified engineering unit. The value can be displayed with the physical measurement value of the sensor and be saved into the data file with the converted values.

Calculation function between channels

Four arithmetic operations (Addition, subtraction, multiplication and division) are available using two analog input channels.
* Data can be saved only in GBD file format.

 Example 

CH2 = CH3 * CH1
(CH2 is a value obtained by multiplying the values of CH3 and CH1)
* Value of calculated results are displayed and saved into data file.

Trigger function

Alarm function & signal output

Threshold of an alarm can be set for each channel. When an alarm occurs, notification is sent by following methods.

Alarm threshold

Analog input: High, Low, Window-in, Window-out
Logic input: H or L (signal in each channel)
Pulse input: High or Rising, Low or Falling, Window-in, Window-out
When alarm is detected

• Display to screen (Digital value of alarm’s origin channel is displayed in red)
• Save alarm information to measurement data file
• Output alarm signal
  Number of channel: 4 channels (Output channel can be arranged to each source channel in OR condition.)
  Signal type: Open collector (pull-up to 5 V with 10 kΩ resistor), maximum load is the 24 V and 100 mA.
  * Requires Input/Output cable for GL series (B-513 Option).

Y-T waveform monitor screen

Displays data with analog waveform and digital value. Screen can also be split into 1, 2, 4 or 8 zones to display the channels in different zones.

Digital monitor screen

Displays current data in digital value and results of real time statistical calculation. (Function: Maximum, Minimum, Peak-to-peak, and Average)When displays only current data, it can be shown in 1, 2, 4 or 8 zones.

Past waveform monitor screen

Display the past part of the data while capturing data. Execute without stopping measurement and also scroll past data. Data screen can be switched with past and current.

XY graph monitor screen

Emulates the classic XY chart recorder. Also supports features for pen up/down and position movement.

Long term recording is made possible with 4 M samples/ch built-in

RAM and 4 GB built-in Flash memory. It supports both USB Flash memory and SD Card memory to be used as external storage devices for recorded data for certain sampling intervals.

Memory division function

Ring mode

Built-in RAM can be divided into 1, 2, 4, or 8 blocks with multiple high-speed recording measurement using the trigger function.

 Single block 
When multiple measurements are executed, the captured data is overwritten in memory block 1.

 Divided into 8 blocks 
When multiple measurements are executed, recorded data is stored in the next memory block.

Saves most recent data of specified number after recording stops.

Number of capturing data  1000 to 10000000 data
* When using built-in RAM, 10 to 4000000 data

Relay mode

Save & replay data in CSV format

Save data to multiple files with specified capturing time or file size (up to 4 GB) until recording data is stopped.

Captured data can be saved with GBD (binary) and CSV (text) format. CSV format file can be played on GL2000 and opened with spreadsheet software.

Backup interval: 1, 2, 6, 12, 24 hour(s)

Auto save function

Search function

Recorded data saved in a built-in RAM is automatically copied as data file to a built-in Flash memory, SD Flash memory card or USB Flash memory with auto save function. An SD Flash memory card or a USB Flash memory can be used as a backup location when using the built-in RAM. The process will prevent losing any data captured in the built-in RAM by any overwrite or power cycles.

The search function can locate a specific value within the captured data as well as finding abnormal values within data of a long-recorded file.

 Search content 
Search for analog signal levels, logic signal pattern, pulse signal levels or alarm point in captured data.

Analog signal channel: Signal levels in each channel
・Search mode: raising, falling, window-in, window-out
Logic signal channel: Signal level (H or L) in each channel
Pulse signal channel: Signal levels in each channel
・Search mode: raising, falling, window-in, window-out
Alarm: Alarm detected point on selected alarm signal output channel

Web server function

GL2000 can be controlled externally via a network on the WEB browser, which also supports real-time monitoring and ability to use the menu buttons.

FTP server function

File in available storage device on GL2000 except built-in RAM can be transferred or deleted from the PC.

NTP client function

The clock on the GL2000 is periodically synchronized with the NTP server.

Email sending function

Send information when alarm occurs, or when battery is low, or when communication speed drops, or to notify when the space becomes limited on the storage device by an e-mail to specified address. Information can also be sent periodically by settings.
