7.5 Triggers
The following figure shows the menus for trigger 1 and trigger 2. The menu options of the lowest menu
level are surrounded by a bold box. For information on the binary inputs, see Connection section.
• In the case of the Tare setting, a signal of at least 100 ms at the binary input results in the
current measured value of the Strain Gauge Converter being stored as the (new) value for the
tare. As usual, the following applies:
net value = gross value - tare
• In the case of the Adjust setting, a signal of at least 100 ms at the binary input results in the current
measured value of the Strain Gauge Converter being adopted as the value for the adjust.
• In the case of the Zero setting, a signal of at least 100 ms at the binary input results in the current
measured value of the Strain Gauge Converter being adopted as the value for the zero point.
Storing the adjust and the zero point by means of the triggers only makes sense, for example, if you
want to avoid operational actions on the Strain Gauge Converter.
