Digital Weighing Indicator
SI 4100
7. Error & Treatment
7-1. Load Cell Installation
1.Load cell broken
2. Load cell isolation
resistance error
3. Weighing part touches
other devices or some weight
is on the weighing part
4. Summing 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
“EXC+” and “EXC-“ is
about 400Ω ±30
2. Output Resistance of
“SIG+“ and “SIG-” is
about 350Ω ±3.5
3. Isolate Resistance is
more than 100MΩ
Weight Value is
increased regular rate,
but not return to “Zero”
1. Load cell Error
2. Load 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
Load cell broken or Indicator
connection Error
Load cell Check
Load cell connection Check
Power was “ON” when some
weight is on the load cell?
Remove weight on the Load cell
1. Load cell broken or
Indicator connection Error
2. Loading over than Max
Capa.
1. Load cell Check
2. Load cell connection Check
3. Remove over loaded weight
When Maxcapacity/digit value is over 20,000
Re-input the Max Capacity, less than 20,000
(Max Capacity / Digit)
Standard weight value is over than Max Capa
Re-input Standard weight value with Number keys,
under Max Capacity
Standard weight value is less than 10% of
Max Capa
Re-input Standard weight value with Number keys,
more than 10% of Max Capacity
1. Amp. Gain is too big
2. Sig+ and Sig- wire connection error
3. Test weight is not loaded
Check standard weight’s weight with set value.
If there is difference between set value and real
weight, please re-input the value
(set value is too small)
1. Amp. Gain is too small
2. Sig+ and Sig- wire connection error
3. Test weight is not loaded
Check standard weight’s weight with set value.
If there is difference between set value and real
weight, please re-input the value
(set value is too big)
Under “F-function” model, set value is “N.A”
Check the correct value and re-input
When there is continuous vibration on the
weighing part,, indicator can not process
calibration any more.
- Find vibration cause and remove
- Load cell check
- Load cell cable and connecting condition check
