※
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 15 V; when the switch is on, the sink current is 20 mA
or less.)
Caution:
Before plugging in the connectors, unplug the AC adapter.
