Á¦Ç°Á¤º¸Three types of input system enable to measure various phenomenaInput system 1 : Multifunction analog input ports
Contains a highly isolated input system which ensures that signals are not corrupted by noise from other channels. The GL840's inputs are suitable for combined measurements
The standard configuration has 20 analog input channels. It is expandable to 200 channels by adding optional 20 channels extension terminal base unit (B-566) and input
* Accuracy rating for K-type thermocouple at 100¢ªC includes reference junction compensation. Accuracy varies by temperature levels and thermocouple types. The following shows how a standard configuration is expanded to more than 40 channels
GL840 is Graphtec's newest Multichannel Standalone Data Logger GL840 Comes Standard with:
*Optional accessories not included
***All units include standard manufacturer¡¯s certificate for factory calibration*** Two separate GL840 models available
Max Sampling Interval of up to 10ms
GL840 series carries two SD memory card slots SDHC up to 32 GB supported. Captured data can be stored in GBD (Graphtec Binary Data)
or CSV file format.
Capturing time* (when all 20 analog channels are being used with Logic/Pulse inputs turned off).
*Figures are approximate. File size of captured data is 2GB in GBD or CSV file format on this
chart. Sampling interval is limited by the number of channels in use (10ms:1ch, 50ms:5ch, 100ms:10ch). Limited sampling speed is available when digital sensors and GL100-WL are used as a remote monitoring device.
