② Notes for calibrating RI-25W
Set calibration with 8-4 Digital Calibration to delete the data of the values changed by
the actual load calibration.
At this point, the rated output value is 0.6%, and the rated capacity (displacement) of
the sensor is set for the sensor.
(For example, if 4mm sensor indicates up to three decimal places, set to 04.000)
Change the current value to Zero (0) without any displacement of the sensor. Apply
about half (or more) of the measurement range.
The value shown in the indicator ÷ Standard displacement × 0.6 (Rated output
value)= Rated output value.
And calibrate with 8-4 Digital Calibration.
ex.) Assume that the sensor is 4mm and the value expressed as a standard displacement
of 2mm is 1.003.
1.003 ÷ 2.000 × 0.6000 = 0.3009 → Rated Output: 0.3009
If there is a difference between the actual load value and the value displayed in the
indicator, refer to the calibration setup method.
It is not necessary to obtain and calibrate the rated output value (R.O).
And the user can also calibrate with 8-5 Actual Load Calibration.
4) Notes for calibrating RI-20W
When calibrating with 8-4 Digital Calibration, the error can be reduced by modifying
the rated capacity value (displacement). Please correct it using the following method.
a)Set calibration with 8-4 Digital Calibration to delete previous data.
b) At this point, select input form DC0 to 10V and set the rated capacity (displacement)
(for example, if a 50mm sensor indicates up to two decimal places, set to 050.00).
c) Change the current value to Zero (0) without displacement of the sensor. Displace
the sensor with a standard displacement of approximately half (or more than half) of
the measurement range.
Rated Capacity × Standard Displacement ÷ Indicator = Rated Capacity Value
Then, calibrate with 8-4 Digital Calibration.
ex.) Assuming that the sensor rating is 50mm and that the value marked by displacement
of 30mm as the standard displacement is 24.90,
50.00 × 30.00 ÷ 24.90 = 60.24 → Rated Capacity: 060.24
If there is a difference between the actual displacement value and the value displayed
in the indicator, refer to 8-5 Actual Load Calibration.
