Looping; Error Handling - HP Series 37 Reference Manual

Operating Instructions
2.2 LOOPING
You can loop on selected tests by entering the LOOP command with the number of times that you want
the tests to loop.
2.3 ERROR HANDLING
The PICDIAG generates three types of error messages: user input error, test failure, and system failure.
1.
User Input Error Messages - Displayed in response to an invalid user input.
EXAMPLE: When PICDIAG requests the channel number of the PIC to
be
tested. the expected
response is a decimal number between 1 and 15. If your input is different, the following
message is displayed:
1<=CHANNEL<=15
The request for a channel number is repeated until you enter a valid response.
2. Test Failure Error Messages - Displayed when the PICDlAG detects a malfunction of the PIC PCA.
The purpose of this type of error message is (a) to let.
YDU
know that the PIC under test is NOT
functioning correctly, and (b) to identify the failure. .
The test failure error message has three parts. The first part identifies the step number that detects
the error. The second part describes the discrepancy between the actual and expected response to the
test. The third part identifies the probable cause of the error.
EXAMPLE:
Error in Step 38:
No time-out from CSRQDIS.
Check U403, U505.
3. System Error Messages Displayed when an error is probably caused by
something other than the PIC under test.
EXAMPLE:
SEP 84
2-2
System in Step 41:
