6.5.6.8 ShuntCalEnable Method
Syntax:
HRESULT _stdcall ShuntCalEnable(in long CardNo, in long ChannelNo, in long Enable, out
retval long * result );
Description:
Enables/disables the shunt calibration circuit for the selected channel
Arguments:
CardNo The card number (1-16)
ChannelNo The channel number on the card (1-8)
Enable 1 = Enable shunt cal, 0 = disable shunt cal
Returns:
0 if Successful, otherwise an Error Code
Notes:
The Shunt Calibration Resistor control enables / disables the parallel shunt cal resistor across the
dummy resistor. The hardware automatically selects the appropriate shunt value for the current
dummy resistor selection. This method is only applicable for strain gage channels in a quarter-
bridge configuration. In ordinary operation the shunt calibration resistor is disabled. Enable it
when you are performing a shunt cal procedure.
6.5.6.9 RemoteCalEnable Method
Syntax:
HRESULT _stdcall RemoteCalEnable(in long CardNo, in long ChannelNo, in long Enable, out
retval long * result );
Description:
Enables the remote calibration resistor for the selected channel
Arguments:
CardNo The card number (1-16)
ChannelNo The channel number on the card (1-8)
Enable 1 = Enable (connect) remote cal, 0 = disable (disconnect) remote cal
Returns:
0 if Successful, otherwise an Error Code
Notes:
Connects / disconnects the remote calibration resistor into the bridge circuit. Enabling the
remote calibration resistor is only valid for strain gage channels in quarter-bridge configuration.
In ordinary operation, the remote calibration resistor is disabled.
