FUNCTIONS
DISABLE ERROR, Special Function 8 (Error Message Disable and Enable)
DESCRIPTION
Error Messages are one means the Measuring Receiver uses to safeguard measurement integrity.
When the instrument senses a potential error-causing situation, an Error Message code is displayed
to
alert the user of the condition. The
Error
Message code indexes an Error Message, which describes
the current errors. (Refer to Error Mcssagc Siimmary on page 3-285.)
When the Measuring Receiver is in its Automatic Operation mode, Error Messages are selectively
enabled, depending on the measurement being made,
to
assure the broadest range of calibrated
measurements. Some Error Messages, however, can be selectively disabled o r enabled using Special
Function 8. Disable Error performs the same function as Special Function 8.7 (Errors 01, 02, 03, and
04 disabled).
Most combinations of Errors 01 through 04 can be disabled o r enabled by the operator t o customize
the behavior of the instrument to meet a particular set of measurement requirements. Special
Function 8.8 (Errors 01 through 04 enabled) sets
up
the Measuring Receiver as
a
calibrated receiver.
