VERIFICATION COMPLETE *** **** EHD OF VERIFICATION PROGRAM * What the Test Does Test 1. SELF TEST. This test verifies that the 34 78A responds to the HP-18 CLEAR command and performs its internal self test. Test 2. PROGRAM CODES. The test starts by verifying that the 34 78A can send an SRQ and that the computer will respond to it. Next, an illegal code is sent to the 34 78A to be certain that it rejects it. Then, all possible combinations of autozero, function and range codes are sent to the 34 78A. In addition, all display modes, trigger modes and the preset commands are tested. Finally, two readings are taken. One from the the 300V de range that is checked to be sure there are no offsets. The second reading checks for an overload condition from the 2-wire ohms mode. 72
