CALibration[<chan>]:ZERO

Example Setting the calibration value

CAL2:VAL 5.00

Input on channel 2 is 5.00 V

:ZERO

CALibration[<chan >]:ZERO [<readings >[,<period >,[<mode >]]] performs a calibration of the zero offset using the specified number of readings and sample rate on the specified range(s). When this command completes, the new calibration constants will be automatically stored to non-volatile calibration memory unless the CALibration:STORe:AUTO command is set to OFF.

Comments Executable when initiated: No

Coupled Command: No

Before executing CALibration[<chan>]:ZERO, you must do the following steps.

a.If mode is not ALL, use the CONFigure command or the SENSe:VOLTage:RANGe and SENSe:FUNCtion commands to place the HP E1429 in the desired range and using the desired port: i.e CONF<channel>:ARR:VOLT (1000),<range>,(@<port>).

b.Program the input filter and impedance (if applicable) to the desired settings (use the INPut:FILTer and INPut:IMPedance commands).

c.If it is desirable for the new constants to be stored to non-volatile calibration memory upon completion of the CALibration:ZERO command, then set CALibration:STORe:AUTO to ON, and turn calibration security OFF. If a complete calibration involving gain and linearity is to be done, then it may be more desirable to only store the calibration constants when everything is complete; for this case, set CALibration:STORe:AUTO to OFF, and use the CALibration:STORe command to force storage when all calibrations are complete.
