5.3 EDP Command Calibration
Use the following instructions to calibrate the 380 using EDP commands. For information on the EDP commands of the 380,
see
The indicator must respond with OK after each step or the calibration procedure must be done again.
For commands ending with
#s
,
s
is the scale number (1).
1. Enter setup mode (
).
CAL jumper must be removed to perform calibration.
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
to calibrate additional
linearization points, or proceed to
.
7. Apply weight equal to the first linearization point to the scale.
8. Send the command
SC.WLIN.V
n#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.C
n#s
to calibrate the linearization point, where
n
is the linearization point number (1-4).
for up to four total linearization points.
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.
