Calibrate by Torque Command (CT)
The Calibrate by Torque (CT) command tells the unit that you are doing a calibration by
2 point torque or by 5 point torque. The format is CT(number of torques).
Example:
@123CT5
Acknowledge:
@123 Calibrate by Torque – 5 Point
Ready for CTP1 command
Calibrate by Torque Point Command (CTP)
The Calibration by Torque Point (CTP) command can have up to six parts: CTP1
through CTP5 and CTP0. You must have already started a calibration using the CB
and CT commands for any of these commands to function. To read the first torque,
issue the Calibration Torque Point 1 (CTP1) command. The format is CTP1(torque)#.
This will cause the Model 9840 to read 10 seconds of data from the torque cell. These
readings are averaged to obtain the first calibration torque reading. The example uses
0.0 LbI for the first mass. Be sure you have placed the torque on the cell before
entering this command since reading will begin immediately.
Example:
@123CTP10.0#
Acknowledge:
@123 Calibrate Torque 1 Command - Reading...
[10 seconds delay]
Calibrate Torque 1 Command - Ready for CTP2 or CE command
The Calibrate Torque 2 (CTP2) command has the format CTP2(torque)#. This
command can only be issued after the CTP1 command has completed. The example
uses 500 LbI for the second calibration torque. Be sure you have placed the torque on
the cell before entering this command since reading will begin immediately.
Example:
@123CTP2500#
Acknowledge:
@123 Calibrate Torque 2 Command - Reading...
[10 seconds delay]
Calibrate Torque 2 Command - Ready for CTP3 or CE command
Torques three through five are done in a similar manner. The Calibrate Torque Point 0
(CTP0) command completes the 2 or 5-point torque calibration. Remove the torque
