Thames Side Smart Series - LIN, LIN_C y LIN_I (Lin,Lin_C,Lin_1); SPAN (Span); TW SPAN (Fspan)

Configuration and Calibration
3-23
3.9.2 SPAN (span)
- Automatic span adjustment: To automatically adjust the span, place a certified test
weight on the scale and press Enter. The maximum scale value is displayed, if the weight
placed on the scale is different, key in the real value. Press the Enter key and *CALIB* is
displayed while the unit calculates the span coefficient. After accepting it, it is stored.
- Manual span adjustment: to manually introduce the span value the Arrow Down key
(
) has to be pressed. Then we select the corresponding digit with the Arrow Left and Arrow
Right keys (
). The selected digit value is modified with Arrow Up and Arrow Down keys
(
). If a negative value has to be introduced it can only be done with the first left digit. The
negative sign appears after the number 9.
When we want to manually introduce the span value in an indicator with a software
version previous to 1.3XX then the last two digits have to be truncated.
3.9.3 TW SPAN (fspan)
Span fine adjustment. Use the right/left arrow keys to adjust this value. Press Enter
to store the value.
3.9.4 LIN, LIN_C y LIN_I (lin,lin_c,lin_1)
Activates linearity adjustment function.
These are the options:
OFF: Linearity adjustment deactivated
ON: Linearity adjustment activated
RESET: Linearity adjustment deactivated and linearity adjustment parameters
cleaning
In On position, you access parameters LIN POINT, LIN COR.
LIN_C: Applied load (known value of the mass chosen for the correction)
LIN_I: Indication of the applied load
These parameters allow the correction of a possible non linearity in the system.
This adjustment is performed in the point you choose from 0 to MAX.
After adjusting the scale (zero and span), if a linearity error is detected due to a
discrepancy between the load and the system indication, choose a point where discrepancy is
more significant and then adjust linearity.
The linearity error disappears at that point and is fundamentally reduced in the rest of
points (see figure 3.9.4.1).
ATTENTION
The value of zero and span coefficients is obtained by
means of the impression of the parameters (see 3.12.3)
