How do I Retrieve Specific Items From the WT1000/WT2000 Series Instruments Using Pre-IEEE488.2 Commands?

  1. Send the "OFDO" command.
    This command turns all items for output OFF. Therefore no items will be output if you send the "OD" command.
  2. Send the "OF1,1" command to the measuring instrument. This command turns the voltage value (V) from element 1 ON, so that the voltage on element 1 will be read out.
  3. Send the "OF2,1" and "OF3,1" commands to turn ON the current value (A) and power value (W) output from element 1.
  4. Send the "OD" command and read out the measured data. 3 data values are output as shown in the following example.

    Example Output:
    V 1N 004.083E+0,A 1N 050.008E+0,W 1N 0202.69E+0
    The first data (004.083E+0) is the V value on element 1, the next data (050.008E+0) is the A value on element 1, and the last data (0202.69E+0) is the W value from element 1.
    The "V….1N" portion before each value is called the header, and expresses, from left to right, the measurement function, element, and data condition.
