GL980 is equipped with an isolated input mechanism to protect signals from interferrences caused by noise from other channels. 16-bit A/D converter adopted to achieve hi-speed and hi-resolution measurements.
Voltage, temperature, humidity, logic and pulse measurements can all be take
Adopts large TFT LCD with multiple methods for displaying information
Simple operation with cursor and enter keys with six pre-set menu screens on large LCD
Long term recording is made possible with 4 M sampling/ch built-in RAM and 4 GB built-in Flash memory. It supports both USB Flash memory and SD Card memory to be used as external storage devices for recorded data for certain sampling intervals.
