HP 3468A - Page 52

One approach to program writing uses “ Building Block” subprograms to simplify
programs. With this approach, you write a mainline program that uses sub-
programs that already exist. The following program provides seven measurement
subprograms and an eighth subprogram that sets-up the 3468A for the measure-
ment, triggers the multimeter, and reads the measurement data to the calculator.
The seven measurement subprograms are used to specify the type of measure-
ment to be made and then branch to the eighth subprogram.
Do not erase the INI68 program before loading the building block program. This is
done by executing the following command before any other program is entered:

The subprograms, by label and function are:
LABEL FUNCTION
MVDC Measure Volts DC. MVDC, along with subprogram 00, sets the 3468A
to take one dc voltage measurement.
MVAC Measure Volts AC. MVAC, along with subprogram OO, sets the 3468A
to take one ac voltage measurement.
M20HM | Measure 2-wire ohms. M2OHM, along with subprogram 00, sets the
3468A to take one, 2-wire resistance measurement.
M40HM Measure 4-wire ohms. M40HM, along with subprogram OO, sets the
3468A to take one, 4-wire resistance measurement.
MADC Measure Amps DC. MADC, along with subprogram OO to set the 3468A
to take one dc amps measurement.
MAAC Measure Amps AC. MAAC, along with subprogram OO to set the 3468A
to take one ac amps measurement.
MXOHM | Measure Extended ohms. MXOHM uses subprogram OO to set the
3468A to take one, Extended ohms measurement. See later example.
