C Strain Gauge Converter Installation Instructions
Gross/Net, Span, Inverted
• By means of the Gross/Net parameter, you determine whether the value for the Span is a gross
value or a net value (gross value minus current tare
).
• By means of the Span parameter, you determine the measured value range which is represented
by the current output.
− The span must be entered in the selected unit.
− If you have selected Gross, you can enter values between 1 % and 100 % of the maximum cell
load.
− If you have selected Net, you can enter values between 1 % of the maximum cell load and the
value of the maximum cell load minus the current tare.
• If you select Inverted
→ normal, the measured value 0 is converted into the start value of the
current
output and the Span is converted into the end value (for the Strain Gauge Converter
always +20 mA). If you select Inverted
→ inverted, the Span is converted into the start value of
the current output and the measured value 0 is converted into the end value.
