Name/Code #
Definition
Action
Command Status 7 C2 clones
C2 load cell has a non-Hardy C2 load cell. Verify the use of Hardy load
cells.
Command Status 8 Hard Cal Fail
Counts
Too few A/D counts between zero and
span points during hard calibration. Input
must change by a minimum amount
between the cal low and cal high points.
Add weight to the scale and
see if readings increase.
Check voltages as in ADC
Convert Error.
Command Status 0x0B (11 dec)
Value is set too high.
Verify the value is within the
tolerance for the parameter
being written to. Verify the
parameter ID is the correct ID
for the parameter you wish to
write to.
Command Status 0x0C (12 dec)
Value is set too low.
Verify the value is within the
tolerance for the parameter
being written to. Verify the
parameter ID is the correct ID
for the parameter to which
you want to write.
Command Status 0x0D (13dec)
Value is not allowed.
6.2 Weighing System Test
The Weighing System test diagnoses drifting or unstable weight-reading problems. For full
utilization, this test requires the HI 6020IT or the HI 6010IT Series Junction Box.
The Weighing System Test achieves this by:
Disconnecting the load sensors and engaging a reference internal to the junction box to
determine whether the cable between the instrument and the Junction Box is causing the
problem.
Reading the weight of each load sensor to see whether the load sensor is causing the
problem.
Reading the weight seen by each individual load sensor, and then making appropriate
cornering, leveling, and load-sharing adjustments to the weighing system.
6.3 Electrical Check Procedures
6.3.1 Load Sensor/Point Input/Output Measurements
The HI 6200 supplies up to 5 VDC excitation to as many as eight 350-Ohm load cells/points
per channel. The expected output from each load cell/point depends on the mV/V rating of
the load cell/point and the weight.
