High Speed 1MS/s Simultaneous Sampling with Isolated Input

GL980 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 measurements.

Simultaneous Sampling
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.

 

Multifunction Input 

Measure Repetitive Wave Forms Such as Vibration with Instantaneous Value and Effective Value

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.

Measures Abnormalities in a Repeated Waveform by Effectively Measuring the Corresponding RMS Value

All RMS measurement range with Crest Factor: up to 2

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 

our 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

The trigger in this unit has multiple functions including level trigger of input signal value for each channel.

Trigger action

Start or stop capturing data by triggering

Trigger source

Off, Measured signal level, Alarm, External, Scheduled time, Scheduled day, Elapsed time
* When trigger is used for starting action, level of measured signal can be set for each channel.

Threshold

Analog input: High or Rising, Low or Falling, Window-in, Window-out
Logic input: H or L (4-channel signal pattern)
Pulse input: High or Rising, Low or Falling, Window-in, Window-out
Combination: Level OR, Level AND, Edge OR, Edge AND

 

Alarm Function & Signal Output

Threshold of an alarm can be set for each channel. When an alarm is triggerred 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).

 

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

 

Other Helpful Functions

Delivers reliable measurements 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 fails, 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.)

 

Instrument is in Compliance with JIS Vibration Test for Automobile Type 1 Class A

(Vibration durability test: 5 m/s2)

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.

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.

Ring Mode

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

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.

Data Backup and Hot Swaps

The recorded data can automatically save to other storage device at specified regular intervals during data capture. (Maximum sampling speed: 1 kS/s (interval 1 ms) with GBD format, 100 S/s (interval 10 ms) with CSV format)

When the backup destination is set to a SD Flash memory card or a USB Flash memory device, memory device can be exchanged before the memory capacity becomes full using the key operation.

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.
