3-2
The calibration number is more than a correction factor, or K- factor, for the
sensor. The first five digits represent the low frequency gain. The ninth
through thirteenth digits represent the high frequency gain. Both numbers are
normalized from an ideal number of 10000. Standard configurations use the
low frequency gain, but in noisy applications it may be worthwhile to switch to
the higher frequency. An additional transmitter procedure, called Auto Zero, is
recommended to perform at the higher coil drive frequency. The seventh and
eighth digits represent the zero offset at both frequencies where the nominal
value is 50. Empty pipe functionality is a transmitter feature that is controlled
by a parameter in the transducer block. To turn off this feature, see
Appendix C.
ASSIGNING DEVICE TAG
AND NODE ADDRESS
The 8732E Magnetic Flowmeter Transmitter is shipped with a blank tag. The
device is shipped with a default address of 126.
If the tag or address needs to be changed, use the features of the
configuration tool. The tools do the following:
• Change the tag to a new value.
• Change the address to a new address.
BASIC SETUP
AI Block The Analog Input (AI) function block processes field device measurements
and makes them available to the master. The output value from the AI block is
in engineering units and contains a status indicating the quality of the
measurement. The measuring device may have several measurements or
derived values available in different channels. Use the channel number to
define the variable that the AI block processes. The 8732E transmitter only
supports “Flow” as AI Block variable.
