@123 Calibrate by Mass – 5 Point
Ready for CMP1 command
Calibrate by Masses Point Command (CMP)
The Calibration by Masses Point (CMP) command can have up to six parts: CMP1
through CMP5 and CMP0. You must have already started a calibration using the CB
and CM commands for any of these commands to function. To read the first mass
issue the Calibration Mass Point 1 (CMP1) command. The format is CMP1(mass)#.
This will cause the Model 9840 to read 10 seconds of data from the load cell. These
readings are averaged to obtain the first calibration mass reading. The example uses
0.0 Lb for the first mass. Be sure you have placed the mass on the load cell before
entering this command since reading will begin immediately.

Calibrate Mass 1 Command - Ready for CMP2 or CE command
The Calibrate Mass 2 (CMP2) command has the format CMP2(mass)#. This command
can only be issued after the CMP1 command has completed. The example uses 500
Lb for the second calibration mass. Be sure you have placed the mass on the load cell
before entering this command since reading will begin immediately
Example:
@123CMP2500#

Calibrate Mass 2 Command - Ready for CMP3 or CE command
Masses three through five are done in a similar manner. The Calibrate Mass Point 0
(CMP0) command completes the 2 or 5-point mass calibration. Remove the masses
from the load cell before entering this command since it will perform the shunt
calibration measurement that is recorded for use with the calibration check command.
The format is CMP0.
