How do you run the self tests on the 2465?

Hold down both the Delta V and Delta T push buttons. Now, also press the Slope button. This will bring up a new screen. Release all buttons. Now push the Coupling Up button once to run a series of all tests once. Any failures will be displayed. Note that an "04 failure" simply means it is out of calibration.
