If the load cell signal input to the Model 370/375 has good repeatability and stability, then using
multi-point linearization during calibration may significantly improve the ultimate accuracy of the
data displayed by the Model 370/375. Parameter 119 (P119) enables or disables this feature.
Initially, the same basic procedures as a normal calibration are used to perform a multi-point
linearization. All of the prompts provided will be exactly the same as a standard calibration for
each cal point up to the Cal ~ Good? prompt.
If items are consistently being weighed on either the high or low end of the cell capacity, the
points of calibration can be skewed to either end of the spectrum. Multi-point linearization can
compensate for a cell that is non-linear. Refer to page 61 for the instructions on how to enter the
calibration mode.
First Zero?
1. Remove all weight and press [TARE] or [SAMPLE/Enter].
2. From the Enter Load prompt key in the first calibration point and press [TARE] or
[SAMPLE/Enter].
3. From the Add Load prompt add the weight of the first calibration point and press [TARE]
or [SAMPLE/Enter].
4. For calibration points 2 -5; Simply add the weight which you want to use for the next
calibration point, then key in the value of the applied weight and press [TARE] or
[SAMPLE/Enter]. You may wish to add weight until the displayed weight differs from the
actual applied weight and then perform the next calibration at that point.
Reset Cal
1. Press
[TARE] or [SAMPLE/Enter].
2. From the First Zero? prompt remove all weight and press [TARE] or [SAMPLE/Enter].
3. From the Enter Load prompt key in the first calibration point and press [TARE] or
[SAMPLE/Enter].
4. From the Add Load prompt add the weight of the first calibration point and press [TARE]
or [SAMPLE/Enter].
5. For calibration points 2 -5; Simply add the weight which you want to use for the next
calibration point, then key in the total applied weight and press [TARE] or
[SAMPLE/Enter]. You may wish to add weight until the displayed weight differs from the
actual applied weight and then perform the next calibration at that point.
Up to five calibration points may be established using this procedure. However if fewer
calibration points are required, simply press [TARE] or [SAMPLE/Enter] without entering a value
at the PntX prompt. Refer to Figure 4-1 for graph examples of 5-point calibration.
