CAT III Compatible, High Voltage and True-RMS Data Logger High-speed High-Voltage Isolated 4 channel Measurements midi LOGGER HV GL2000.
GL2000 midi LOGGER isolated 4-ch high-voltage and high-speedGL2000
Main Features:
High speed 1 MS/s simultaneous sampling with isolated input.
GL2000 is equipped with an isolated input mechanism to protect signals from interferences caused by noise from other channels. 16-bit A/D converter adopted to achieve hi-speed and hi-resolution measurement.
- 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.
Multifunction input with CAT III measurement category
Voltage, temperature, humidity, logic and pulse measurements can all be taken simultaneously in high speed.
- 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. - Trigger function
>The trigger in this unit has multiple functions including level trigger of input signal value for each channel. - Alarm function & signal output
>Threshold of an alarm can be set for each channel. When an alarm occurs, notification is sent by following methods.
Large Easy-to-read 7-inch LCD
Monitor data in multiple methods in addition to digital value display and full waveform display screen.
- 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.
Quick and Easy Set Up Process
Simple operation with cursor and enter keys, and menu-driven operation with six pre-set menu screens: AMP, DATA, DISP, TRIG, I/F (Interface) and OTHER.
- Delivers reliable measurements out at a location with unstable power supply.
>Equipped with three types of options for power source, AC adapter, DC input, and battery pack. With a battery pack, GL2000 runs continuously for approximately 3 hours. If an AC power failure occurs, it will automatically switch from the AC adapter to the battery pack. Additionally, when the voltage of the battery pack reaches low, measurement is automatically stopped after saving the data file preserving the accumulated data. (Requires two battery packs (B-569 option) installed.)
Supports large built-in RAM (4MS/ch) and built-in Flash (4 GB)
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.

Convenient Data Recording Functions
- Memory division function
>Built-in RAM can be divided into 1, 2, 4, or 8 blocks with multiple high-speed recording measurement using the trigger function. - Ring mode
>Saves most recent data of specified number after recording stops. - Relay mode
>Save data to multiple files with specified capturing time or file size (up to 4 GB) until recording data is stopped. - Save & replay data in CSV format
>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. - Data backup and hot swaps
>he data file can be created periodically for purpose of backing up data while recording it, and the file is automatically transferred to another storage device on the unit or FTP server on the network.
Backup interval: 1, 2, 6, 12, 24 hour(s). Backup file destination: Built-In Flash memory, SD memory card, USB memory device, FTP server
Data file format: GBD (binary) or CSV (text)
* The CSV format and FTP server are available with firmware version 1.14 or rater.
−Available sampling speed is the 100 ms or slower when using the CSV format.
−When the RING mode or external pulse synchronization sampling is selected for recording, the backup function is not available.
−The storage device specified as the recording destination of the measurement data can not be set as the transfer destination of the backup file.
−When backup is enabled and data file format is specified with CSV format, SD memory card exchange (hot-swapping) and RELAY recording are not available. - Auto save 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. - Search function
>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.
Equipped with Ethernet (LAN) and USB interface to communicate with PC
- Convenient function with LAN (Ethernet interface) capability
>When GL2000 is connected to LAN using the Ethernet interface, networked computer can monitor real-time measured value, transfer files, and change set ups without using application software (GL980_2000-APS software). - 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. - USB Drive Mode to Easily Transfer Files to PC
>The USB drive mode function allows simple data transfer to the PC from built-in Flash memory and SD Flash memory card which acts as USB Flash drive on GL2000. It also allows to add, remove, and delete files from storage device on GL2000 from PC file browsing explorer.
