Abstract
A programmable leak tester is implemented to include the ability for performing a math step in conjunction with the program steps. The math step can use as inputs the result of a previous step, a register value, or a previous compensation or calibration value. As outputs, the math step can provide a compensation or calibration value for use in the execution of another program, can provide a register output, or can be provided as the step result for the current step. By using multiple math steps, the programmable tester provides flexible and adaptable leak testing in a variety of applications.
Claims18
A method of leak testing using a programmable leak tester having outputs and transducer inputs, the method comprising the steps of:
- storing a leak test program having a series of steps;
- and
- selecting an equation in said program by performing the steps of:
- choosing one of a plurality of equations having a plurality of input variables and an output variable;
- selecting for each of the plurality of inputs one of:
- a register value;
- a compensation value;
- a calibration value;
- or
- a step result;
- and
- selecting for the output one of:
- output comp value;
- output cal value;
- output step result;
- or
- output register.
A programmable leak tester comprising:
- output controls;
- a display;
- a stored program for programming leak tests, the stored program comprising:
- code to accept selection of one of a plurality of equations having a plurality of input variables and output variables;
- code to select for each of the plurality of inputs one of:
- a register value;
- a compensation value;
- a calibration value;
- or
- a step result;
- and
- code to select for the output one of:
- output comp value;
- output cal value;
- output step result;
- or
- output register.
