niSwitch Write Calibration Data [OBSOLETE]
Writes the calibration data, typically in terms of the amplifier offset, in the EEPROM.
The NI PXI-2501 has an amplifier that may require periodic calibrations. You can perform the necessary calibration and store the data locally on the switch module EEPROM. The calibration date is also stored in the EEPROM.

instrument handle identifies a particular NI-SWITCH session established with niSwitch Initialize With Topology, niSwitch Initialize With Options, or niSwitch Initialize. | ||||||

channel name specifies the name of the channel calibrated. Examples of valid channel names: ch0, com0, ab0, r1, c2, cjtemp Refer to Devices for a complete list of valid channel names. While niSwitch Read Calibration Data and this VI take a channel name, some switch modules only support a single calibration for all input channels. For example, the NI PXI-2501 uses an optional single amplifier for channels ch0 through ch47 to decrease settling time. In these cases, writing a different value to a different channel causes the previous value to be overwritten. Therefore, reading different channels returns the same calibration data. For more information on calibration, refer to Devices. |

calibration field tells NI-SWITCH which particular calibration parameter associated with this channel to write. Valid values depend on the switch hardware. Examples of valid fields: CJTEMP Amp Calibration (0), Channel Amp Calibration (1) Default value: 0 |

error in describes error conditions that occur before this VI or function runs.
The default is no error. If an error occurred before this VI or function runs, the VI or function passes the error in value to error out. This VI or function runs normally only if no error occurs before this VI or function runs. If an error occurs while this VI or function runs, it runs normally and sets its own error status in error out. Use the Simple Error Handler or General Error Handler VIs to display the description of the error code. Use error in and error out to check errors and to specify execution order by wiring error out from one node to error in of the next node.

calibration data is the calibration data to store in the EEPROM. | ||||||
 |
instrument handle out identifies a particular NI-SWITCH session established with niSwitch Initialize With Topology, niSwitch Initialize With Options, or niSwitch Initialize and used for all subsequent NI-SWITCH calls. |

 |
error out contains error information. If error in indicates that an error occurred before this VI or function ran, error out contains the same error information. Otherwise, it describes the error status that this VI or function produces.
Right-click the error out indicator on the front panel and select Explain Error from the shortcut menu for more information about the error.
