Safety Guide for using GLT400 If a voltage exceeding the specified value is input, the semiconductor relay used in the input section is damaged. Never input the voltage exceeding the specified value at any moment. Maximum input voltage of standard terminal (B-564) and screwless terminal (B-564SL) <...

Unused channels The analog input section of the GLT400 contains a capacitor to improve the noise removal capability. Therefore, when the input terminal is in open sate, the measurement result may be affected by the signals of other channels. In such a case, set the input to "Off" or short between +/- terminals.
Supplied Software Two types of software applications for Windows OS are provided on this GLT400. Please use it according to the purpose. • Use the "GLT 400 Setting App" to change the settings. • Use "GL-Connection" to check the waveform of the input signal in real time or to capture the input signal.
The ability to interface with GL840 GLT400 Remote Mode By communicating with the midi LOGGER GL840 series via a wired LAN/wireless LAN connection, you can use the GL840 as the base unit and the GLT400 as the Remote Unit (remote terminal) for batch capturing on the GL840 base unit. Maximum 5 units, up to a total of 200 channels including the number of channels of GL840, can be captured at the same time.
