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.
WAVERSAVER can factor out noise with frequencies as low as 0.25 Hz or as high as 7.5
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.
Weighing System Tests
These tests are used to diagnose drifting or unstable weight reading problems. It requires a
Hardy IT Junction Box for full utilization, for example the HI 215IT or the HI 6010IT. The
ability to read the weight seen by the individual load sensors allows you to use this test for
making cornering, leveling and load sharing adjustments to the weighing system.
INTEGRATED TECHNICIAN provides the following problem detection support:
1. Integrated Technician Weight and Voltage Test: Reads the weight of each load
sensor in the system to see if the load sensor might be causing the problem.
2. Integrated Technician Stability Test: Disconnects the load sensors and engages
an internal (in the junction box) reference signal to see if the Junction box, the cable
between the instrument and the Junction Box, or the instrument is causing the
problem.
3. Integrated Technician Return to Zero Test: Measures and stores the mV out of
each Hardy load cell during a C2 calibration when zero is used as the reference.
Later when the test is run it measures and compares the voltage with zero weight out
from each load cell to the stored value and indicates either a pass or fail. This test
insures the integrity of the weighing system.
