Graphtec GL900-4 High-speed isolated 4-channel multifunction logger

Graphtec GL900-4 High-speed isolated 4-channel multifunction logger

In compliance with various test requirements, this data logger is capable of performing high-speed simultaneous voltage and temperature measurements

Easy-to-use upright high-speed isolated 8-channel multifunction logger
An easy-to-use upright device enabling isolated 8-channel multifunction input, the GL900 is capable of performing high-speed simultaneous measurements of voltage, temperature, and various other phenomena.
Voltage: +/-20 mV to +/-500 V
Temperature Thermocouples: K, J, E, T, R, S, B, N, W
Humidity: 0 to 100% (the B-530 option is required)
Pulse: 4 channels Count, Inst., Rpm
Logic: 4 channels ‡ 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
Long-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.

Can be used as an X-Y recorder
The 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
The 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.

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.

Convenient functions
Various convenient data-processing functions are built in.
Direct to Excel function
This function enables measurement data to be written directly to an Excel file.
Search function
This function enables searching for specific values in the captured data.
CSV batch conversion function
This function enables batch conversion of multiple captured files to CSV file format.
Thumbnail function
This function enables display of captured data files as thumbnails.
