RADIANQBIO INSTRUMENT

9. Product Inspection

Symptom
When Display
trembles.
When weight goes
up at a regular ratio
or zero returns are
not made.
When weight
changes into (-).
Displayed as Lc_Er
Displayed as c_Err
If the number on
the Display does
not match
Pressing key
in FUNC state does
not move to
calibration mode.
The number of
measurements is
incorrect
When the
measurement
changes are not
constant or
insignificant. (RI-
20W, 25W)
Cause
 Load cell is damaged.
 Load cell insulation resistance.
 Indirect occurrence
 Loadcell faulty
 Loadcell connection is
insufficient.
 Loadcell wiring is
reversed.
 Load cell is damaged.
 Load cell connection is
bad.
 Actual calibration set
below zero (-)
 Out of maximum display
range(-19999 ~ 99999)
 Locked State at 8-7
Lock Set-up.
State in which units of
conversion at F-51 Force
unit is established.
 Maximum Display
Range Out of 99999
 Sensor Cable Swapped
or Open
 Sensor damaged or
faulty supply voltage
(EXC) occurred
 Calibration setup error
 Load cell input, output.
 Check resistance
 Check load cell's insulation resistance.
 Check load cell's insulation resistance.
 Check the wiring between load cell and the
main device.
 Check the load cell's calbe's disconnection.
 Check load cell's ouput cable connection.
 Check the load cell's condition and calbe
connection.
 Performing actual load calibration at plus(+)
 Re-check the 8-4 Digital Calibration setting
and the F-51 Force unit setting.
 Restore to the settings saved by RESTORE execution
 Unlock from Locking Settings at 8-7 Lock
Set-up.
 Change to kgf unit (set value :0) at F-51.
Force unit
 Check calibration settings and F-51
settings. (page 30~36), (page 29)
 Restore to the settings saved by RESTORE
execution (page 37)
• Check cabling status
• Checksensor supply voltage (EXC) and
output
• Check DIP S/W (page 9) (RI-20W)
• Check calibration settings (page 30-36)
