INTEGRATED TECHNICIAN
INTEGRATED TECHNICIAN® (IT) is an optional diagnostics utility that enables the operator to rapidly
troubleshoot individual load cells. The option requires an HI 215IT or HI 6010IT Summing Box (shown
above) that provides distinct inputs for each load cell.
Without the HI 215IT or HI 6010 Summing Box, it is difficult to isolate the signals from different load cells.
If any load cell fails, the test will output a FAIL response without identifying the problem load cell. For
numerical values, the system will return an average of all the load cell responses and, in some cases, will
return values that cannot be used.
The HI 215IT or HI 6010 Summing Box with the IT firmware can provide the HI 6600 both average
numerical values and values specific to each load cell, including PASS/FAIL values for each load cell, as
shown below.
To view this screen on your system, see Diagnostics The number of load sensor(s) is based on the connections
in the IT junction box. Check the installation sequence in the box to determine which load sensor is number 1,
2 and so on. You can use the IT functions from either the Optional Front Panel or Web interface. If you do
not have the optional IT junction box, some of the options described below will not appear on either interface.
Stability Test
The Stability test lets you check the A/D Raw count and filtered. With the IT option, it tests and reports for
each load cell. The test sends the load cell data to the analog-to-digital converter and calculates the mean
squared variation from the average reading, using 100 samples. The test passes if the mean squared variation
is less than 5.0.
If the weighing system passes the stability test, the results show OK and the variation and mean results are
posted. FAIL indicates that the Mean Squared Variation is greater than 5.0 so the system is considered
unstable. In that case, see the Troubleshooting Flow Charts Section.
