6 Input/Output to/from External Devices
LF(R) Series Operation Manual
You can set a tare range or adjust the zero-point from an external device by
connecting a contact or a transistor switch between the pin for externally setting a
tare range (Pin 9) and the signal ground pin (Pin 5). When doing so, allow at least 400
ms for connection (ON) time (Maximum voltage when the balance is turned OFF: 15
V, sink current when it is turned ON: 20 mA).
