EDP Command Calibration
Use the following instructions to calibrate the 380 using EDP commands. For information on the EDP commands of the 380,
see
Section 7.0 on page
35.
The indicator must respond with OK after each step or the calibration procedure must be done again.
Note
For commands ending with #s, s is the scale number (1).
1. Enter setup mode
CAL jumper must be removed to perform calibration.
Note
2. For a standard calibration, remove all weight from scale (except hooks or chains which are needed to attach weights).
3. Send the command SC.WZERO#s to perform a standard calibration of the zero point.
• Send SC.TEMPZERO#s to perform a temporary zero calibration
• Send SC.LASTZERO#s to perform a last zero calibration
4. Apply the span calibration weight to the scale.
5. Send the command SC.WVAL#s=xxxxx, where xxxxx is the value of the span calibration weight applied to the scale.
6. Send the command SC.WSPAN#s to calibrate the span point. Continue on to
linearization points, or proceed to
7. Apply weight equal to the first linearization point to the scale.
8. Send the command SC.WLIN.Vn#s=xxxxx, where n is the linearization point number (1-4) and xxxxx is the exact
value of the weight applied.
9. Send the command SC.WLIN.Cn#s to calibrate the linearization point, where n is the linearization point number (1-4).
10. Repeat
steps 7–9
11. If hooks or chains were used to attach the weights, remove all weight, including the hooks and chains, and send the
command SC.REZERO#s to remove the zero offset.
12. Send the command KSAVEEXIT to return to weigh mode.
