4-3. Preparation for Calibration
4-3-1. Setting Initial Data
Minimum data items required for performing proper calibration are: Excitation voltage, Minimum
scale division, Sensor rated output value, and Sensor rated capacity value. Initial setting data are
registered when F130 is powered on or it restarts.
Excitation voltage selection (m)
Select the bridge voltage supplied to the strain gauge type sensor.
The bridge voltage can be selected from 2.5V and 10V.
After this setting, be sure to perform calibration.
(Setting range
0: 2.5V, 1: 10V)
Minimum scale division (m+1)
Set the increment of the indicated value.
(Setting range
1 to 100)
Sensor rated output value (m+5)
Set the rated output value of the strain gauge type sensor for Equivalent input calibration.
Since the set value is reflected when the calibration is executed (ON edge of the Equivalent input
calibration request), set before execution.
(Setting range
50 to 3100 (0.050 to 3.100mV/V))
Sensor rated capacity value (m+6)
Set the indicated value corresponding to the actual load for Actual load calibration.
Set the rated capacity value of the strain gauge type sensor for Equivalent input calibration.
(Setting range
1 to 32000)
Since calibration value data are stored separately for excitation voltage 10V and
2.5V, it should always be determined before performing calibration operation, and
it should not be changed after calibration.
If the maximum excitation voltage of the strain gauge type sensor is under 10V, be
sure to select 2.5V.
Attention
Set each set data properly within the setting range.
In the case of setting out of the setting range, normal operation may not be
performed with measurement value and hold value.
* If out of the setting range, "1" is returned to the 12th bit of (n+1)CH "setting error
occurrence."
