Weight and Voltage Tests
The Weight and Voltage tests are used to diagnose a weighing system and, if certain types of problems are indicated,
determine their source. It provides the total scale input to the instrument such as mV, mV/V and Weight in the units
selected (i.e. lbs, kg, oz, g).
Weight and Voltage Test from the Web interface
Since the IT Web page shows all the weight and voltage values at once, it is the preferred method for troubleshooting.
Click Integrated Technician to open the Diagnostics - Integrated Technician page.
To view individual load sensor data, click Do IT Test.
These readings are snapshots and allow you to determine if the problem is in the instrument (internal) or in a load sensor(s)
(external).
The specification range for the Weight Processor is 0-25 mV, so a reading between 0-25 mV is within the normal range. A reading
outside this range would normally indicate that the problem is external to the system (most likely improper wiring).
If all the load sensor readings are 0.00, something is wrong between the HI 6600 and the junction or summing box box or with
the summing or junction box itself. Either the cable is disconnected, or something is causing the junction box to not transmit the
readings to the HI 6600.
If you do not get a reading for one or possibly two or more load sensors (Sensor 3 for example reads 0.00 or the reading is
either larger or smaller than it should be) and you know that the Load Sensors are connected to the junction box, the
individual load sensor cable is disconnected from the junction box or the load sensor is malfunctioning.
Running the IT test from the Optional Front Panel
The same information can be obtained from the Diagnostics menu. Select Enter to show the menu. Then select
Jbox1 to run the test. To read the rest of the results, press the down arrow.
