5.9 Running IT Tests
Path:
Home screen > Operation Menu > Diagnostics > IT Test
The Diagnostics IT screen allows you to perform an IT test and reduced IT test (faster and
fewer tests), and then view the results. If your system has an Integrated Technician
Summing Junction Box, the IT test can help identify individual load cell problems for up to
four load cell selections.

INTEGRATED TECHNICIAN (IT
®
) is an optional diagnostics utility that allows you to troubleshoot
individual load cells rapidly. The option requires an HI 6020IT or HI 6010IT Summing Junction
Box (see Figure 5-5) that provides distinct inputs for each load cell.
Without the HI 6020IT or HI 6010IT Summing Junction Box, there is no way to isolate the signals
from different load cells. If any load cell fails, the test outputs a FAIL response without identifying
the problem load cell. For numerical values, the system returns an average of all the load cell
responses and, in some cases, will return values that cannot be used.
With the HI 6020IT or HI 6010IT Summing Junction Box and IT feature, the application controller
can provide both average numerical values and values specific to each load cell, including
PASS/FAIL values for each load cell, as shown in Table 5-4.
