1. A portable device for determining a status of a tanker truck safety system, the device comprising:
- a microprocessor configured to run a program to determine the status of a tanker truck safety system;
a plurality of spring-loaded pins configured to couple with corresponding contact pads on the truck safety system, the plurality of pins coupled to a plurality of inputs of the microprocessor;
a first intrinsically safe power supply controlled by the microprocessor and coupled to a first subset of the plurality of spring-loaded pins and configured to provide a first intrinsically safe voltage to each pin individually under control of the microprocessor; and
a second intrinsically safe power supply controlled by the microprocessor and coupled to a spring-loaded pin not in the first subset of pins and configured to provide a second intrinsically safe voltage to the one pin under control of the microprocessor,wherein the first and second intrinsically safe voltages are on separate rails.

Abstract
A hand held portable truck safety equipment tester uses loading rack criteria to confirm proper operation of the truck but is contained in a small portable battery operated unit. This unit allows for correlation to a rack controller'"'"'s test and includes direct readout via an LED screen showing the error condition. Additionally, the tester has the capability to test all types of trucks without the need for adapters to accommodate different connectors and allows for remote diagnostics. The tester automatically determines which type of sensor and what grounding system is used.

20. An adaptable connector comprising:
-
a generally cylindrical handheld housing having a circumferential portion defined about an opening at a first end thereof; a first pin extending radially into the opening and located at a first position about the circumferential portion; a first through hole radially oriented with respect to the opening and at a second circumferential position that is at a predetermined relationship to the first position; a second through hole radially oriented with respect to the opening and at a third circumferential position that is at a predetermined relationship to the first and second positions; and a first movably positionable pin located in and extending radially into the opening from only one of the second and third through holes. - View Dependent Claims (21, 22, 23, 24)
