SETTING SENSITIVITY
Select the sensitivity setting procedure according to the target condition.
CHANGE THE SETTING VALUE
You can change the setting value in “excess gain display” mode or “setting value display” mode.
For sensitivity adjustment using a moving target
z Fully-automatic Calibration
1. Pass a target through the
optical axis while pressing the SET button.

CUE: When the sensitivity difference is insufficient
If sensitivity has no allowance after calibration, “------” flashes for 3
seconds on the LCD display monitor.
Note: Sensitivity is set and registered even when the sensitivity difference is insufficient. Be sure to confirm that detection is properly performed.
CUE: Locking the operation button (Key protect)
Hold down [MODE] and [UP] simultaneously for 3 seconds to lock the
operation button. When the operation button is locked, “Loc” is displayed in flashing letters.
To unlock the operation button, repeat the procedure above. “vnL”
(unlocked) is displayed in flashing letters.
Even when the operation button is locked, display data and channel
can be changed.

The minimum input time is 20 ms.
3. The external calibration procedure is the same as using the SET button. Turn the input device on instead of pressing the SET button.
Also, turn the input device off instead of releasing the SET button.
(You can perform all the setting procedures described on the left.)
CUE: Calibration input during detection
You can re-adjust sensitivity during detection without stopping the
operation.
The sensor continues operation with the previous sensitivity setting
until sensitivity readjustment is completed.
CUE: External calibration with several units
When several units are connected, the sensitivity of all the FS-T2(P)
expansion units can be simultaneously set using the external calibration input through the FS-V1(P).
You can select a unit to be externally calibrated by setting its key protection switch to the LOCK position.
External calibration is effective for all the units which are locked. Set
the key protection switch to LOCK on the FS-T2(P) expansion unit to
be externally calibrated.
