(2) Connect between the expansion terminal bases with the expansion terminal connection cable.
* Push the expansion terminal connection cable until it is completely locked.
Install the extension terminal bases in a stable location and be careful not to fall.
(3) Connect the other end the expansion terminal connection cable to the terminal connector on the GLT400.
Push the expansion terminal connection cable until it is completely locked.
Do not touch.
● When a signal is input to the connected terminal, do not touch the pins of the connector or the terminal
next to the connector.
● When disconnecting the expansion terminal connection cable from the GLT400 or the expansion
terminal base, please note the following:
• Always pull out the cable straightly while pushing the lock release levers on both sides.
• Do not forcibly disconnect, or do not forcibly pull out the cable while pushing the lock release lever of
the one side only.
Please note that this may cause a poor connection of the connector.
● When the expansion terminal connection cable is used, it is easily affected by noise.
When the GLT400 is affected by noise, reduce the sampling rate.
● When adding the terminals, connect them continuously without omitting the terminals in between. If you
omit the terminal in between, the terminals after that is not recognized.
● When using the standard terminal or the screwless terminal in combination with the high-voltage, high-precision
terminal, the withstand voltage must conform to the specifications of the standard or screwless terminal.
● When using the GL800 or GL820 terminal in combination, the temperature measurement accuracy may
not meet the specifications.
