The ERROR Option
This menu option permits programming of the manner in which the
Model GF868’s outputs respond during an error condition. See
Chapter 2, Error Codes and Screen Messages, of the Service Manual
for a discussion of the built-in error codes.
Note:
The error responses listed in Table 1-7 above apply only to the
CH1/CH2 measurement mode and to the SUM / DIF
measurement modes, if either or both channels are in error.
Error handling in the
AVE
measurement mode is set below.
The 2-path error handling option is intended for applications where
two sets of transducers are installed in the same location in the same
pipe to improve accuracy and the meter is operated in
AVE mode.
With this function enabled, the Model GF868 performs error handling
only if both channels are in error. If this function is disabled, error
handling occurs when either channel goes into error.
Global Error Action Press
[F1]-[F4]
to select the
desired error response for the
CH1/CH2 , SUM or DIF modes,
as described in Table 1-7 below.
