‡ Select either Pulse or Logic

*) The input signal needs to be not exceeding the specified voltage at any time.
The component in the amplifire of the unit may have the damage by over voltage.
Please check the details of over voltage in the specification sheet (Maximum input voltage or Withstand voltage seccion) or the caution label attached on the unit.

Data can be captured to PC-friendly USB memory sticks

img_02.jpgLong-term data can be captured directly to built-in 256-MB flash memory or to an external USB memory stick at sampling intervals of from 1 ms to 1 min. For high-speed sampling at intervals faster than 1 ms, up to one million data points can be captured to internal RAM.

The USB memory stick must be a standard model (without fingerprint recognition or other proprietary features).

Can be used as an X-Y recorder

img_03.gifThe GL900 reproduces analog X-Y recorder movements and provides the illusion of pen up/pen down movements. It can be operated like an analog X-Y recorder and can also be used as a 4-pen X-Y recorder. The digital data format facilitates post-measurement confirmation of data values and report creation.

High-precision temperature measurement even during high-speed sampling

Lets users perform high-precision temperature measurements even during high-speed sampling – ideal for performing combined voltage and temperature measurements.

Comprehensive built-in trigger and timer functions

Using a combination of trigger and timer functions eliminates superfluous data and enables capture of only the required data.

High-voltage measurement capability

The wide 500 V range enables 100 to 240 VAC power supply voltage waveform measurements. Using logic input and a clamp meter simultaneously allows measurement of a device’s power supply voltage and current concurrently with sequential control of various points.

Built-in, large-format 5.7-inch color LCD for easy-to-read waveforms

The bright, easy-to-read large-format 5.7-inch color TFT LCD provides vivid, easy-to-read waveform displays. Cursor keys enable fast, easy control and setup. The waveform display can be scrolled at high-speed – 10 ms/DIV.

Free Running display for waveform-checking without the need for data capture

img_08.gifThe Free Running display lets users check input signal waveforms even before measurements begin. Since waveforms are displayed on each setup screen, users can make settings while viewing the waveforms.

Easy PC measurement via USB; remote monitoring via Ethernet web server and FTP functions

The USB and Ethernet connections enable transfer of captured data to your PC and setup and control of the GL900 from a PC, even without the PC software provided standard with the GL900.

img_09.jpg

Web server/FTP server functions

Waveform display and GL900 setup operations can be performed via a web browser (e.g., Internet Explorer). In addition, data files captured to the GL900’s internal memory or to a USB memory stick can be transferred or deleted from the PC.

USB drive mode

When your GL900 is connected to your PC via the USB interface, the GL900 can be operated in USB mode to enable fast, easy data transfers from internal memory to the PC.

NTP client function

Simply connect the GL900 to an NTP server via an Ethernet connection to synchronize GL900 time with NTP server time at periodic intervals

Dedicated software for real-time data capture

Three measurement screens are provided to allow selection of the screen that best suits measurement needs.
The Replay screen provides a Zoom screen feature to enable enlarged display of specific sections of long-term measurement data.

Description

With its color monitor and internal memory the GL900 is a self-contained, compact, lightweight, multi-channel data logger with 8 analog measurement channels, each with input-to-output and channel-to-channel isolation. Measurements per channel of 20mV to 500V FS across 14 programmable ranges allow the GL900 to adapt to a wide range of signal types, including thermocouple-based temperatures (K,J,E,T,R,S,B,N,W) and process current (4-20 mA). Up to four pulse channels can count and measure speed using an optional cable, and Humidity measurements are also possible with an optional sensor. The GL900 may be configured to trigger up to four different alarm outputs as a function of measured values.

The GL900 allows data to be recorded to internal high-speed volatile RAM memory (64 MB) at rates as fast as 100,000 Hz. The unit also provides built-in non-volatile memory (256 MB) and accepts external USB flash drives (2 GB maximum file size) for lower speed sampling as fast as 1,000 Hz. The minimum sample rate for all memory configurations is one sample per minute.

The GL900 features built-in USB and Ethernet ports to facilitate data transfer to a connected PC either in real time or from its memory for analysis and archiving. Measurement protocols may also be uploaded from the PC to the instrument. An optional battery pack allows power-independent operation and failsafe measurement continuity during a power failure.
