5.5-4 Section 5: Using the Model 9100: Procedure Mode
5.5.3.3 High Voltage Warning
After pressing OK or REPEAT PREV. keys:
If the procedure writer has not conformed strictly to the procedure-writing guidelines,
LETHAL VOLTAGES MAY APPEAR WITHOUT WARNING AT ANY POINT IN
THE PROCEDURE. ANY WARNING BEEPS SHOULD BE TAKEN VERY
SERIOUSLY!
Emergency Action
In emergency, the most effective way of turning output off (other than pulling the line-
power plug) is to press the OUTPUT OFF button on the right of the front panel. This may
sound obvious, but a special feature of the OFF button operation is that as well as sending
the appropriate message to the operating system, it also has a hardware link which
bypasses the software. Even if the program has locked up, this button is effective in
cutting off the output.
5.5.3.4 'OK' / 'FAIL' Screen Keys
The use of the 'OK' and 'FAIL' screen keys (or the left/right buttons of a mouse)
is to inform the 9100 whether or not it was possible, by slewing the source, for the UUT
measurement to be set to the target value.
'FAIL' Key
If, by slewing, the UUT measurement cannot reach the target value, the 'FAIL' key should
be pressed. This will cause the 9100 to register the test as an 'Invalid Reading', and print
this on the certificate.
'OK' Key
If, by slewing, the UUT measurement acquires the target value, the 'OK' key should be
pressed. This will cause the 9100 to register the test as a 'Valid Reading'. From the amount
of slew (slew error) from nominal which is required to reach the target value, the 9100
will place the test into one of three categories:
• Fail: The slew error is greater than 100% of the specification tolerance for
that particular test point.
• Borderline: The slew error is equal to or less than 100% of the specification
tolerance for that particular test point; and greater than a percentage of
that tolerance set by the user as 'borderline' within Config mode.
• Pass: The slew error is equal to or less than a percentage of the specification
tolerance for that particular test point, set by the user as 'borderline'
within Config mode.
