The internal 
measurement value 
(R.V.) is displayed 
as 
[
-ffff
]
.
The internal measurement 
value (R.V.) falls below the 
lower limit (-99.999) of display 
range.
• Check the setting for shift target value and shift 
the display again.
“3-5 Zero Shift Function (Shifting the 
Internal Measurement Value (R.V.))”
(page 3-18)
• Redo the calibration.
“Calibration Function” (page 4-45)
The internal 
measurement value 
(R.V.) is displayed 
as 
[
ffff
]
.
The internal measurement 
value (R.V.) goes beyond the 
upper limit (99.999) of display 
range.
The bank switching method is 
set to external input.
To switch the banks with button operations, set 
“12. Bank switching method” to [btn].
When the R.V. (Internal 
Measurement Value) is 
[-----], the tolerance tuning 
and the 2 point tuning will 
occur, and, when the P.V. 
(Judgment Value) is [-----] 1 
point tuning will occur.
When the internal measurement value (R.V.) and 
judgment value (P.V.) is a number value, conduct 
tuning by the condition of the measured 
measurement object.
“Setting the Tolerance Setting Value” (page 3-10)
• When the R.V. is [-----], 
the zero shift function was 
used.
• When the “3.AVE” is [HPF], 
the zero-shift was used.
• Shift the display when the internal 
measurement value (R.V.) is displayed (with 
the object measured).
“Zero Shift Function (Shifting the Internal 
Measurement Value (R.V.))” (page 3-18)
• Make sure the “3.AVE” is not [HPF].
“3. Averaging rate, Step count filter, 
High-pass filter” (page 4-9)
The SET1, SET2, or SET3 value 
is incorrect and the correction 
using the calibration function 
could not be performed.
Perform the calibration within the possible 
correction range.
“Calibration Function” (page 4-45)
The button operation is 
disabled.
The connected communication unit <DL-RS1A> 
read/write setting switch is set to RW.
Set the read/write setting switch to R.

The light amount is saturated.
Tilt the sensor head so that regular reflectance 
beam is not received.
