measurement applications. By eliminating the factor
of vibratory forces the module is capable of identify-
ing the actual weight data. WAVERSAVER

can be
configured from the Configuration Software to ignore
noise with frequencies as low as 0.25 Hz. One of five
higher additional cut off frequencies may be selected
to provide a faster instrument response time. The
default factory configuration is 1.00 Hz vibration fre-
quency immunity.
C2
®
Calibration
C2 Second Generation Calibration enables a scale
system to be calibrated electronically without using
certified test weights which equals the systems load
capacity. A C2 weighing system consists of up to
eight (8) C2 load sensors, a junction box, interconnect
cable and an instrument with C2 capabilities such as
the HI 1746-WS Weight Scale Module. All Hardy C2
certified load sensors contain digital information
detailing its unique performance characteristics. The
HI 1746-WS reads the performance characteristics of
each individual load sensor and detects the quantity of
load sensors in the system. C2 Calibration can be per-
formed by pressing “The Button” located in the front
of the module, or via Hardy’s Configuration Software
or Allen-Bradley’s RS Logix 500 software.

Excitation Monitor
Continuously monitors a system’s excitation current
to check for open or shorted load sensors or damaged
or broken excitation wire(s), including the wires
between the module and the
IT Junction box. If the
measured current deviates more than a +/- 10% toler-
ance, an “Excitation Error” bit (Module Status Word
bit 9) is set to 1.
