3.3.3Jupiter Configuration Parameters
This set of parameters within the Transducer Block is important and required to configure every Jupiter transmitter.
MEASUREMENT_TYPE Select from LEVEL_ONLY or
LEVEL&INTERFACE.
PROBE_LENGTH Enter the exact length of probe. The probe length is shown as the last 3 digits of the probe model number printed on the nameplate attached to the transmitter.
LEVEL_OFFSET Enter the distance from the probe tip to the desired 0% reference in PROBE_LEVEL_UNITs. The acceptable range is from
SENSOR_MOUNT Select from MLI_TOP, MLI_BOTTOM, DIRECT_NEAR or
DIRECT_EXTENDED.
3.4User Calibration Parameters
One of the main advantages of the Enhanced Jupiter Model 2XX is that every Enhanced Jupiter Model 2XX transmitter is shipped from the factory precisely calibrated.
On the other hand, part of the advantage of FOUNDATION fieldbus is to provide the ability to monitor changes and adjustments to a transmitter. The Fieldbus concept allows a user to make calibration adjustments if deemed necessary.
NOTE: The original factory calibration settings are restored when a new probe length value is assigned.
It is highly recommended that factory calibration be used for optimum performance.
3.4.1Factory Parameters
The
CONVERSION_FACTOR, SCALE_OFFSET, FLOAT_THRESHOLD and FLOAT_POLARITY.
The following parameters are used for either troubleshooting or are parameters adjusted at the factory. They should never be changed in the field.
CONVERSION_FACTOR: compensates for changes in signal propagation.
SCALE_OFFSET: the intercept of the calibration line.
FLOAT_THRESHOLD: controls the threshold voltage level.
FLOAT_POLARITY: defines level as positive or negative pulse.
SENSITIVITY: signal detector adjustment.
DRIVE_AMPLITUDE: sets amplitude of the out going pulse.
