A minimum compliance voltage of 17.75 is required
to guarantee HART communication.
Compensation
Transducer compensation: for ambient temperature .
Density parameter compensation: for process
temperature (requires user‐supplied tables).
Manual compensation: for torque tube rate at target
process temperature is possible.
Digital Monitors
Linked to jumper‐selected Hi (factory default) or Lo
analog alarm signal:
Torque tube position transducer: Drive monitor and
signal reasonableness monitor
User‐configurable alarms: Hi‐Hi and Lo‐Lo Limit
process alarms

RTD signal reasonableness monitor: When RTD
installed
Processor free‐time monitor.
Writes‐remaining in Non Volatile Memory monitor.
User‐configurable alarms:
Hi and Lo limit process
alarms, Hi and Lo limit process temperature alarms,
and Hi and Lo limit electronics temperature alarms
Diagnostics
Output loop current diagnostic.
LCD meter diagnostic.
Spot specific gravity measurement in level mode:
used
to update specific gravity parameter to improve
process measurement
Digital signal‐tracing capability: by review of
“troubleshooting variables”, and
Basic trending capability for PV, TV and SV.
LCD Meter Indications
LCD meter indicates analog output on a percent scale
bar graph. The meter also can be configured to
display:

Minimum Differential Specific Gravity
With a nominal 4.4 degrees torque tube shaft
rotation for a 0 to 100 percent change in liquid level
(specific gravity=1), the digital level controller can be
adjusted to provide full output for an input range of
5% of nominal input span. This equates to a minimum
differential specific gravity of 0.05 with standard
volume displacers.
