Description s.
Remarks This function characterizes the Inductance measurement path and source, which is
required prior to making inductance measurements. It should be performed within one
hour, before using the inductance measurements. For better accuracy it should be
performed more frequently. The Open Terminal calibration should be performed with the
test leads open. The DMMOpenTerminalCal sweeps the inductance stimulus source
across the full bandwidth, and makes measurements at several points. It takes about
twenty seconds to complete the process. For a complete characterization of the
Inductance measurement system it is also necessary to perform the inductance zero
operation with the inductance range and frequency selected, using the Relative function
and with the probes shorted.
