Rotation Change is the change in torque tube deflection from Zero Reference Angle (deg).
Buoyant Force is the currently measured Buoyant Force (lbf).
= Rotation Change * Mechanical Gain
Apparent SG is the apparent Specific Gravity (SG).
= BuoyantForce / ReferenceBuoyancy
Preliminary PV i s the Displacer Volume covered by liquid (in
3
).
= BuoyantForce / FluidDensity
Scaled PV is the displacer length covered by lower fluid (in).
= DisplacerLength *(BuoyantForce/DisplacerVolume -UpperFluidDensity)/(LowerFluidDensity-UpperFluidDensity)
Final PV = Sc Level DisplacerRise (in), when PV is Liquid Level or Interface Level.
= ReferenceDensity * ApparentSG (lb/in
3
), when PV is Liquid Density.

Electronics Monitors are variables tracked by hardware alert monitors.
Input Circuit contains the signal and diagnostics menu.
Hall Sensor Signal is the output of the Hall sensor signal amplifier. The valid range is 300 to 960 mV.
If slightly out of range, the lever is on/near travel stop.
Check to see if:
The displacer is removed, the instrument coupled with the displacer is removed, or if there is a severely bent or
broken flexure.
If 1230 mV, the Hall sensor input circuit is open or shorted to the high side.
If very erratic at steady process condition, the transducer circuit card is bad.
Hall Sensor Drive is the diagnostic measurement of the Hall sensor bias current, usually near 725 uA.
Processor is the execution cycle diagnostics menu.
Free Time Remaining is the unused portion of microprocessor execution period.
Writes Remaining is the Non-Volatile Memory life cycle diagnostics menu.
Configuration NVM is the remaining writes available to the microprocessor NVM (configuration data). The
Configuration NVM writes start at 10,000 and is decremented for each write.
Transducer NVM is the remaining writes available to the sensor board NVM (factory characterization data). The
Transducer NVM writes start at 65,535 and is decremented for each write.
Buffer NVM is the remaining writes available to the electronics module NVM (buffer for firmware upgrades). The
Buffer NVM writes start at 65,535 and is decremented for each write.
