midi LOGGER HV GL2000

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.


 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

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).

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.

Other helpful functions

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.)

Instrument is in compliance with JIS Vibration Test Method for Automobile Type 1 Class A.
(Vibration durability test: 5 m/s²)

Carrying case (B-581) [comming soon]
Portable case to store GL2000 and signal input cables for easy handling.

Cover
Protect the main body from cosmetic damages and minor impacts. GL2000 is shipped with cover attached.
* The cover is not to protect from hard impact.

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


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

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.

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.

 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
