Voltage or Current Output Using Retransmission Module
When clibrating the retransmission module by confirming the output value, connect a DMM (a
product corresponding to HP3458A) to the terminal to be calibrated.
Calibration Procedure
1 Connect the equipment as described above.
2 Verify that the calibration conditions are satisfied.
3 Start the DAQ Software 32.
4 Start the calibration program by clicking the [Calibration] icon.
5 Carry out the calibration operations (A/D adjustment) conform the DAQ Software 32 User’s
Manual (IMDP12013-62E).
Note
Instead of operating the DAQ Software 32, calibration can also be carried out by communication interface
using the [XZ] command. For details concerning this command, refer to the User’s Manual “Data
Acquisition Unit Communication Interface”, IMDA100-11E.
