External contact input
External contact input is not available on verified balance.
Zero-point adjustment can be executed from an external device by connecting a contact or a transistor
switch between the pin for external zero-point adjustment(Pin 9) and the signal ground pin (Pin 5) of the
D-sub9P Connector. When doing so, allow at least 400 ms for connection (ON) time (Maximum voltage:
15 V when the balance is turned OFF, sink current: 20 mA when it is turned ON).
(1) While external contact input is selected, command input is not available.
(2) There is no response command corresponding to external contact input.
