GL980 is equipped with an isolated input mechanism to protect signals from interferrences caused by noise from other channels. 16-bit A/D converter adopted to achieve hi-speed and hi-resolution measurement.
GL980 utilizes simultaneous sampling to eliminate slowdown in sampling rate by using multiple A/D converters in simultaneous sampling method. Eight individual A/D converters in each channel sustains the maximum sampling speed for all eight 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.
Voltage, temperature, humidity, logic and pulse measurements can all be taken simultaneously in high speed.
Measures either instantaneous value or effective value (RMS). By utilizing the trigger feature to measure abnormal spikes in the
continuous waveform, users can measure vibration abnormalities repeatedly.
All RMS measurement range with Crest Factor: up to 2
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
Four arithmetic operations (Addition, subtraction, multiplication and
division) are available using two analog input channels.
* Data can be saved only in GBD file format.
The trigger in this unit has multiple functions including level trigger of input signal value for each channel.
Threshold of an alarm can be set for each channel. When an alarm occurs, notification is sent by following methods.
Monitor data in multiple methods in addition to digital value display and full waveform display 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
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.
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.
Emulates the classic XY chart recorder. Also supports features for pen up/down and position movement.
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, GL980 runs continuously for approximately 2 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.)
Storage case (B-581)
Portable case to store GL980 and signal input cables for easy handling.
* The case is not to protect from hard impact.
Protect the main body from cosmetic damages and minor impacts. GL980 is shipped with cover attached.
* The cover is not to protect from hard impact.
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
Approximate recording time
■ 8 channels of analog input. ■ Data is saved as a GBD file.
|Built-in RAM||4 M samples/ch||4 seconds||40 seconds||66 minutes||46 days|
|Built-in Flash memory||3.9 GB||N/A||N/A||2 days 6 hrs.||Over 1 year|

* When using 8 GB or larger memory, the size of data file will be up to 4 GB. The Relay mode enables extended recording time.
Built-in RAM can be divided into 1, 2, 4, or 8 blocks with multiple high-speed recording measurement using the trigger function.
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
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 GL980 and opened with
The 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.
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.
When GL980 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).
GL980 can be controlled externally via a network on the WEB
browser, which also supports real-time monitoring and ability to use
the menu buttons.
File in available storage device on GL980 except built-in RAM can be
transferred or deleted from the PC.
The clock on the GL980 is periodically synchronized with the NTP
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.
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 GL980. It also allows o add, remove, and delete
files from storage device on GL980 from PC file browsing explorer.
