* Tare subtraction (zero adjustment) is possible by connecting an external tare
subtraction input and a signal ground through contacts or a transistor switch. When
following this procedure, secure a connection time of at least 400 milliseconds (when
the switch is off, the voltage maximum is 15V; when the switch is on, the sink current
is 20 mA or less).
Before plugging in the connectors, unplug the AC adapter.
