TESTRESULTS
0x6C
Report the results of a previous
INTEGRATED
TECHNICIAN test. No new
test is performed

O:0-0x6C
O:1-15 (unused)

I:0x6C
I:1 = return to zero test result,
bit coded:

• Bits set to 1 indicate non-

return to zero.

• Bit 0 = combined weight
• Bits 1-4 (JBOX only)

indicate non-return to
zero on a individual
JBOX sensor.

I:2-15 are all INTEGER
values.

• Millivolt/volt readings

have 4 decimal places.

• Load Cell resistance has

zero decimal places.

• Sense Volts has 2 decimal

places.

I:2 = millivolts/volt,
combined, LSW
