6 Specifications of the LK-G Series

* ON/OFF indicates the ON/OFF status of the NPN or PNP open-collector output.

* Valid/Invalid indicates the validity/invalidity of input.

* HOLD represents the state in which the normal value immediately before is being held.

* The RESET processing is performed after the mode is changed to the measurement mode, pro-

gram number is changed, auto-zero processing is completed, and RESET input is accepted.

* USB indicates the communication using the Setup support software "LK-Navigator".

* The setting mode indicates the state where setting is performed by key operations on the display

panel.

* The communication mode indicates the status where setting is performed via RS-232C or USB

communication. RS-232C and USB cannot be used at the same time.

* Moving to the communication mode and returning to the measurement mode are performed auto-

matically on the Setup support software "LK-Navigator".

* Using RS-232C and USB at the same time in the measurement mode lowers the response speed.

* The comparator output is issued when the comparator output format is set to normal.
