Each channel contains 62 calibration constants. The following list describes what
the constant is at each array index location. The array is assumed to start with index
number 0.

:DELay
CALibration[<chan >]:DELay will calibrate the delay constant for the A to D
converter. Both channels are calibrated with this command, regardless of which
<chan> value is specified. This calibration only needs to be done once or twice in
the lifetime of the instrument. Also, this calibration determines a nominal value for
convert time at room temperature (25 degrees C). It is, therefore, important that this
command be executed at an ambient temperature near 25 degrees C.
