7-1. Load Cell Installation
Error
Cause
Treatment
Remark
Weight Value is
unstable
1.oad cell broken
2.oad cell isolation
resistance error
3.eighing part
touches other devices or some
weight is on the weighing part
4.Suming Board Error
1.Measure input/output
resistance of Load cell.
2.Measure Load cell
isolation resistance
3.Check attach point
with other devices.
1.Input Resistance of “EX+”
and “EX-“ is about
350Ω~450Ω.
2. Output Resistance of “EX-
“ and “EX+” is about 350Ω.
3. Isolate Resistance is more
than 100Ω
Weight Value is
increased regular
rate, but not
return to “Zero”
1.oad cell Error
2.oad cell connection Error
1.Check Load cell connection
2.Measure Load cell Resistance
Weight Value is
increased to
under Zero
Load cell Output wire (SIG+,
SIG-) is switched
Make wire correction
“UN PASS”

7-2. Calibration Process
Error
Cause & Treatment
Err 01
When {Max.capacity/digit} value is over 20,000
Err 04
Standard weight value is over than Max. Capacity
Err 05
Standard weight value is less than 10% of Max. Capacity
Err 06
1. Amp. Gain is too big 2. Sig+ and Sig- wire connection error 3. Test weight is not loaded
Err 07
1. Amp. Gain is too small 2. Sig+ and Sig- wire connection error 3. Test weight is not loaded
Err 08
Under “F-function” mode, set value is “N.A”
Err A
When there is continuous vibration on the weighing part,, indicator cannot process calibration.
