The test for pass or fail may take 30 seconds to settle. It will always show the load cells as fail when the test is started.
The reduced voltage is a Yes or No selection. Then run the J-box test 1 as appropriate.
A more detailed explanation of each section of the test follows below:
Stability Test ALL
PASS/FAIL and Stability Test
This test computes the variation of the A/D counts. The results show the variance and indicate pass or fail. The test
is valid to help break down the problem into smaller divisions. Unstable test results can be caused by an internal
A/D processor fault, grounding, power connection, EMI/RFI above specified CE limits, or noisy load cell input.
These numbers reflect a weight change at the smallest measurement of the filter setting, the internal analog-to-digital
converter computer register.
WAVERSAVER TEST
These numbers also reflect weight change at the smallest measurement, the internal analog- to-digital converter
computer register. The internal RAW A to D counts and filtered A to D counts are displayed for a comparison.
A FAIL on the RAW counts and pass on the filtered counts indicates the WAVERSAVER filtering is
necessary and functioning properly.- except that this reading is averaged using the WAVERSAVER and
AVERAGES setting parameter from the Processor’s configuration. Using the maximum number of internal
averages and the 10ms update speed equals a maximum delay of 2.55 seconds
Weight and Voltage ALL
This test section looks at the readings from ALL the load cells to test overall system performance and signal
voltage readings. This test works for most load cell types.
