Error Messages
When  CAL[1]|2:RCAL is ON and the sensor currently connected to the 
appropriate channel (A or B) has not been zeroed and calibrated, then any 
SCPI command which would normally return a measurement result (for 
example, FETC?,  READ?,  MEAS? etc) does not return a result and generates 
the error –230, “Data corrupt or stale; Please zero and Cal.”
After the sensor has been zeroed and calibrated the return measurement 
results commands function normally.
CAL1:RCAL? This command queries whether or not the 
zero/cal lockout facility is enabled for 
Channel A.
