Sensoray Model 118 Smart A/D™ Instruction Manual 26 Commands: Pressure/Strain Gage

6.4.2 SetGageZero

Informs the Smart A/D that there is presently no load

applied to the target channel’s gage. The Smart A/D

registers this condition and uses it as a reference for all

subsequent measurements on the target channel.

Typically, this command is executed just before invoking

the SetGageSpan command. Acting together, the

SetGageZero and SetGageSpan commands serve to

completely calibrate a gage channel.

Driver

// Issue a Set Gage Zero command for the specified channel.

VOID SetGageZero( USHORT BasePort, UCHAR Channel )

{

SendByte( BasePort, Channel | CMD_SET_GAGEZERO );

}

Example

See the programming example shown for the SetGageSpan command.

Command: (176 + Chan)

Response: None
