Storing the
Adjustments
Once all adjustments have been made, you can store the new calibration
constants in non-volatile memory by sending the following command:
/* Store the new constants */
CALibration:STORe
This command will generate an error if the Cal Store Enable Jumper
is not set to the CAL position (see page 62).
Note
The HP E1418A will be busy storing the new calibration constants
following the CAL:STOR command. You should not perform any
bus resets or module resets until the store is complete. You can use
the *OPC? query to determine when the command has finished.
Verify the
Adjustments
Run the Performance Verification Tests, beginning on page 34,
to verify the adjustments made.
Return the Module
to Use
If you have changed the position of the Cal Store Enable Jumper
(as described on page 62) and you wish to prevent writing calibration
constants to non-volatile memory, set the jumper to the SECURE position.
If you have changed the position of the terminal jumpers, as described on
page 16, return the jumpers to their original positions.
Example Program
The following program, written in ANSI C illustrates a full calibration of all
channels for both voltage and current. The internal calibration resistor is
used. The disk provided with this manual contains a calibration example
file. This example uses function calls to the HP VISA Transition Library for
I/O operations.
