Function Tree Node: \Boonton55xxx\Instrument Specific\Channel\Zero Query

Declaration: Btn55xxx.h

Implementation: Btn55xxx.dll

Visual C++

ViStatus Btn55xxx_ZeroQuery(
ViSession Vi,
ViConstString Channel,
ViInt32 Calibrator,
ViBoolean* Val
);

Parameters

The ViSession handle that you obtain from the IviDriver_init or IviDriver_InitWithOptions function. The handle identifies a particular instrument session.

Channel

The physical or virtual repeated capability identifier. Pass VI_NULL or empty string if operation does not apply to a repeated capability.For valid values, see the Channel repeated capability.

Calibrator

The calibrator type to turn off during zeroing.

Val

Returns true if successful or false if not.

Return Value

Success or failure code.

Remarks

The sensor does not need to be connected to any calibrator for zeroing ? the procedure is often performed in-system. However, this command will turn off the internal calibrator (when installed) prior to zeroing to avoid the need to perform this step explicitly.

Instrument Command

CALibration{Channel}:{INT|EXT}:ZERO?
