Displacement Sensor Calibration - KYOWA WP-120A Instructions For Use Manual

ATTENTION
Incorrect connections or settings could cause damage to
sensors.
AUTO DIGITAL FILTER
When the input signal is stable, the unit can temporarily
set the filter's moving average number to 1024, reducing
indicator value unsteadiness.
This function can be disabled by setting it to OFF.
o This will affect the display and judgment of continuous
judgment mode, but the effect will not be applied to
hold and judgment values.
DIGITAL OFFSET
The set value is subtracted from the measured value.
o When the digital zero function is executed, the value
shown is 0 minus the digital offset setting value.
D/Z LIMIT SETTING
Set the range for digital zero capture. (The setting value
unit is the same as for the indicator value.)
ATTENTION
If the current sensor input value exceeds the D/Z LIMIT
SETTING value, "The Digital Zero Limit is being exceeded. "
appears and the indicator value does not become zero.
Equivalent input calibration, actual load calibration and TEDS
calibration setting methods are explained in "4-3. Load cell
calibration" on page 31.

calibration
To open the DISPLACE. SENSOR screen, touch the buttons in
the following order on the Home Screen.

UNIT SHOWN
This sets the unit shown for displacement.
CALIBRATION LOCK
When "ON", calibration values cannot be changed.
o Keep this "ON" normally so that values are not changed
unintentionally.
INPUT MODE
This sets the displacement sensor output signal.
SENSOR INPUT LOGIC
The sensor input logic can be reversed artificially.
Normally, "STANDARD" should be used.
