calibration. When the HI 6600 series instrument reads the signals from the load sensors, it calibrates the scale
based on the load sensor’s output plus a user-supplied reference point value (from 0 to any known weight on
the scale).
INTEGRATED TECHNICIAN
®
In conjunction with an IT junction box, the HI 6600 series features INTEGRATED TECHNICIAN® (IT), a
system diagnostics program that makes it possible to diagnose weighing system problems from Hardy’s Web
Server or a connected optional display panel. IT reads individual load sensor voltages and weights and isolates
individual system components for quick and easy troubleshooting
NOTE: If you do not have a Hardy IT Junction Box connected to the HI 6600, the weight reading is the total for all
load cells on the system.
WAVERSAVER
®
When measuring small weight changes, the effects of mechanical vibration and noise from feeders and other
plant environmental conditions can introduce substantial interference. WAVERSAVER factors out vibration,
noise, and other interference-related signals from the load cell so the weight processor can better decipher the
actual weight data.
While WAVERSAVER can factor out noise with frequencies as low as 0.25 Hz, five cut-off frequencies can
be selected, with higher frequencies providing a faster response time. The default factory setting is 1.00 Hz
vibration frequency immunity.

Power Requirements for Configuring Your Modular Sensor
System over Distance
Distributing power over Cat5e cabling to a fully loaded HI 6600 system (up to 28WPM units, up to 28 junction
boxes and up to 120 350 Ohm load cells) is beyond the current carrying ability of Cat5e cable.
Deploying a fully loaded system up to 500 feet poses no harm to the instrumentation or sensors. However, the
current required can prevent the system from discovering modules that do not have enough voltage available or
trip an over-current protection circuit until the condition is cleared.
Weight Processing Modules may require auxiliary power for systems consisting of a large number of channels
at large distances or that use non-Hardy load cells that have varied input resistances.
Below is table 1 showing the maximum number of units of specific distances running over Cat5e without any
additional power.
