Sets the GPIB address.
Assigns the upper half of the LCD screen to measurement result
display and the lower half to the HP Instrument BASIC, and
terminates the sweep.
Stores the permittivity of vacuum into the E0 variable.
Stores the conditions to adjust the electrodes into variables.
Stores the measurement conditions to evaluate the capacitance of the
LOAD standard into variables.
Stores the limit range of the air capacitor, used as the LOAD standard,
into variables.
Stores the OPEN standard values (resistance value: 100 GΩ,
inductance value: 0 H), the SHORT standard values (resistance value:
0 Ω, inductance value: 0 H), and the LOAD standard values
(conductance value: 0 S) into the Open_r, Open_l, Short_r, Short_l,
and Load_g variables, respectively.
Stores the band width setting and the diameters of electrodes A and B
into variables.
Displays the message at the start of the program.
Passes control to a subroutine named Select_elec to select the
electrodes to be used.
Passes control to a subroutine named Adapter_setup to set up the
adapter.
Passes control to a subroutine named Adjust to adjust the electrodes to
