Calibrate by mV/V Torque and Volt Commands (CMVT and CMVV)
The Calibration by mV/V Torque (CMVT) and Volt (CMVV) works exactly like the
Calibrate by mV/V Mass and Volt commands. These commands can have up to seven
parts each: CMVT1 through CMVT6 and CMVT0; and CMVV1 through CMVV6 and
CMVV0. You must have already started a calibration using the CB and CMV6
commands for any of these commands to function. To input the first torque issue the
Calibration by mV/V Torque 1 (CMVT1) command.
The torque is entered using the
following format: CMVT1(torque value)#. Entering this command will result in the unit
prompting the user for the first milli-volt per Volt command.
Example:
@123CMVT15.0005#
Acknowledge:
@ 123 Calibrate Torque 1 Command entered
Ready for mV/V Value CMVV1 or CE command
The CE or Calibration Escape command will, if entered, end this calibration without
calibrating the unit. The unit will remain calibrated according to the most recent
calibration or, if this is the first calibration of the unit, the unit will remain un-calibrated.
At this point the unit is prompting the user for the first milli-volt per Volt value of the
calibration. The mV/V value is entered using the Calibration by mV/V Volt Command
with the following format: CMVV1(mV/V value)#.
Example:
@123CMVV11.9926#
Acknowledge:
@ 123 Calibrate mV/V 1 Command entered
Ready for Torque Value CMVT2 or CE command
The unit will continue to prompt the user for mass and milli-volt per Volt values until the
six points have been entered. Then the user will see the following acknowledgement:
@ 123 Calibrate mV/V 6 Command entered
Ready for Torque Value CMVT0 or CE command
The user must now enter the CMVT0 command to finish the calibration. Note the
torque cell should have no torque on it at this point since a shunt calibration is run.

@123CMVT0
