Indirect occurrence

Load cell input, output.

Check resistance

Check load cell’s insulation resistance.
When weight goes
up at a regular ratio
or zero returns are
not made.

Loadcell faulty

Check load cell’s insulation resistance.

Loadcell connection is
insufficient.

Check the wiring between load cell and the
main device.



Actual calibration set
below zero (-)

Performing actual load calibration at plus(+)
If the number on
the Display does
not match

Out of maximum display
range(-19999 ~ 99999)

Re-check the 8-4 Digital Calibration setting
and the F-51 Force unit setting.

Restore to the settings saved by RESTORE execution
Pressing key
in FUNC state does
not move to
calibration mode.

Locked State at 8-7
Lock Set-up.

State in which units of
conversion at F-51 Force
unit is established.

Unlock from Locking Settings at 8-7 Lock
Set-up.

Change to kgf unit (set value :0) at F-51.
Force unit
The number of
measurements is
incorrect

Maximum Display
Range Out of 99999

Check calibration settings and F-51
settings. (page 30~36), (page 29)

Restore to the settings saved by RESTORE
execution (page 37)
When the
measurement
changes are not
constant or
insignificant. (RI-
20W, 25W)

Sensor Cable Swapped
or Open

Sensor damaged or
faulty supply voltage
(EXC) occurred

Calibration setup error
• Check cabling status
• Checksensor supply voltage (EXC) and
output
• Check DIP S/W (page 9) (RI-20W)
• Check calibration settings (page 30-36)
