MULTI-CAL-SYSTEM: HP34401A" -410" Error Using Multi-Cal-EVM Program

Part Number: MULTI-CAL-SYSTEM
Other Parts Discussed in Thread: PGA308, PGA309

I installed the Multi-Cal-EVM program on a PC with newly installed Windows 10 and brought the existing scripts and settings,

but the error "-410" on the 34401A does not work for OTP. What's the problem?

    HI Byeong,

    Are you using the multical system with the PGA308 or the PGA309?  Since you mention "OTP" I assume you are using the multical system with the PGA308. 

    I will need to reproduce/research the -410 error on the 34401 multimeter.  If you have a snap shot of the GUI when the error occurs, this would be helpful.

    Thank you,

    Best Regards,

    Luis

    Hi Luis

    I use PGA308 for 3wire.

    The interface board is now connected for testing.

    The four interface boards scan well.

    However, I perform a minimum scan and the voltage at the DMM is normally read by 2.5V to 3V,

    but there is an error in the DMM as shown in the picture and it does not appear in the software.

    The DMM has an error content of "-410".

    In addition, the DMM script is attached.

    The communication settings for the 34401A are:
    INTERFACE: RS232
    BAUD RATE: 9600
    PARITY: NONE 8 Bits
    LANGUAGE: SCPI

    HI Byeong,

    This particular error is related to the RS232 communication and not directly related to the Multi-cal software. 

     From the 34401 multi-meter manual:

    -410 Query INTERRUPTED
    A command was received which sends data to the output buffer, but the
    output buffer contained data from a previous command (the previous
    data is not overwritten). The output buffer is cleared when power has
    been off, or after a *RST (reset) command has been executed.

    On my PC set up, I use a GPIB to USB adaptor, so I will not beable to reproduce the RS232 error.  You could try using the RS232 script attached below  instead; it has a couple subtle differences.  Otherwise, you could consult with the 34401 multi-meter manufacturer for more information.
