A data sheet is attached to a strain gauge type sensor at the time of purchase.
For Equivalent input calibration, the "rated capacity value" and "rated output value"
described on the data sheet are set to the F130: therefore, it should be carefully
stored after calibration.
Attention
4. CALIBRATION METHOD
4-1. What is Calibration?
Calibration is performed for matching the F130 to a strain gauge type sensor.
That is, F130 must be properly adjusted to indicate 10.00kN when an actual load of 10kN is placed
on the strain gauge type sensor.
4-1-1. About Calibration Methods
12
There are two methods of Span calibration: Actual load calibration and Equivalent input
calibration.
Actual load calibration
By this method, calibration value is registered by the value of the actual load applied to the strain
gauge type sensor.
Error-less accurate calibration can be performed.
Equivalent input calibration
By this method, calibration value is registered from the rated output value (mV/V) and rated capacity
value of the strain gauge type sensor. This calibration method using no load can simplify work.

Write initial setting data to the DM area that corresponds to
MACH No.
Register initial setting data to F130. To do this, either power on
the F130, or restart it by toggling restart flag in the following
sequence: OFF → ON → OFF.
Set the mode selection bit (15th bit of nCH) to "1" to establish
the calibration mode.
Register initial zero value by setting the Zero calibration bit
(8th bit of n CH) to “1”.
- Actual load calibration
Register a span by applying actual load to the strain gauge type
sensor.
- Equivalent input calibration
Execute Equivalent input calibration.
(Set the Equivalent input calibration bit (10th bit of nCH) to "1.")
Perform the Zero calibration procedure again if required.
Set the mode selection bit (15th bit of nCH) to "0" to restore the
normal operation mode.
13
4.CALIBRATION METHOD
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."
Attention
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 output value of the strain gauge type sensor for Equivalent input calibration.
(Setting range 1 to 32000)

0: Normal operation mode 1: Calibration mode
On the F130, Zero calibration and Span calibration can be operated by selecting the calibration
mode with the mode selection bit. Use the normal operation mode except during calibration.
4-4. Zero Calibration
Follow the steps below to define correct initial value:
1. Make sure that the strain gauge type sensor is free from unnecessary load, such as foreign object
placed on the weighing plate, or contact with peripheral devices.
2. Make sure that the measurement value (n+2 CH) is stable without fluctuations.
3. Toggle the Zero calibration bit (8th bit of n CH) from 0 → 1.
4.CALIBRATION METHOD
4. F130 starts Zero calibration procedures when it acknowledges an ON edge (0 → 1) of the Zero
calibration bit.
5. Zero calibration in progress bit (8th bit of n+1 CH) turns on “1”. Do not touch the sensing
portion (sensor) while this bit in on.
6. Make sure measurement value (n+2 CH) shows “0”.
7. Toggle the Zero calibration bit (8th bit of n CH) back to “0”.
4-5. Actual Load Calibration
Apply an actual load to the strain gauge type sensor and register the span.
1. Apply an actual load to the strain gauge type sensor.
2. Make sure that the strain gauge type sensor is free from unnecessary load, such as foreign object
placed on the weighing plate, or contact with peripheral devices.
3. Make sure that the measurement value (n+2 CH) is stable without fluctuations.
4. Toggle the Actual load calibration bit (9th bit of n CH) from 0 → 1.
5. F130 starts Actual load calibration procedures when it acknowledges an ON edge (0 → 1) of the
Actual load calibration bit.
6. Actual load calibration in progress bit (9th bit of n+1 CH) turns on “1”. Do not touch the sensing
portion (sensor) while this bit in on.
7. Make sure that the measurement value (n+2 CH) exactly coincides with the sensor rated capacity
value (m+6).
8. Toggle the Actual load calibration bit (9th bit of n CH) back to “0”.
15
4.CALIBRATION METHOD
4-6. Equivalent Input Calibration
1. Toggle the Equivalent input calibration bit (10th bit of n CH) from 0 → 1.
2. F130 starts Equivalent input calibration procedures when it acknowledges an ON edge (0 → 1)
of the Equivalent input calibration bit.
3. Toggle the Equivalent input calibration bit (10th bit of n CH) back to “0”.
4-7. Calibration Error
If calibration operation is performed without properly making strain gauge type sensor input or
initial setting to the F130, a calibration error occurs. Check the calibration error number (n+7 CH),
remove the cause, and then perform calibration operation again.
When the calibration error occurs, "1" is returned to the 11th bit of n+1 CH "setting error
occurrence."
Calibration Error 2
This indicates a state in which Zero calibration cannot be performed because an electric signal
exceeding the input voltage range is input on the positive side. Check the cable for breaks or wrong
wiring.
Calibration Error 3
This indicates a state in which Zero calibration cannot be performed because an electric signal
exceeding the input voltage range is input on the negative side. Check the cable for breaks or wrong
wiring.
Calibration Error 5
Sensor rated capacity value is preset to “0”. Select a proper non-zero value.
Calibration Error 6
The output of the strain gauge type sensor is too small to perform calibration. Check to see if load is
applied properly, or the strain gauge type sensor has such a capability that can make appropriate
output, and then perform Span calibration again.
16
Calibration Error 8
Strain gauge type sensor output is outside the F130’s allowable sensor input range. Check if the
sensor is properly loaded, and the its rated output falls within the F130’s sensor input range.
Perform Span calibration again. Then, perform Span calibration again.
5. MEASUREMENT SETTINGS
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."
Attention
5-1. Analog Filter Selection (m+2)
A low-pass filter is provided for filtering input signals from the strain gauge type sensor and
cancelingnoise components.
The cut-off frequency can be selected from 3Hz, 10Hz, 30Hz, 100Hz, 300Hz, 1kHz.
With an increase in the cut-off frequency, the response becomes faster, but noise components may
be indicated.
(Setting range 0: 3Hz, 1: 10Hz. 2: 30Hz, 3: 100Hz, 4: 300Hz, 5: 1kHz)
5-2. Digital Filter Count Setting (m+3)
This filter calculates moving average of A/D converter output to reduce indicated value fluctuation.
Set by the sampling count of the past data to perform moving average process.
Larger averaging width will enhance indicated value stability, but reduce response performance.
Vice versa, shorter averaging width reduces indicated value stability, but enhance response velocity.
(Setting range 1 to 512)
5.MEASUREMENT SETTINGS
5-3. Digital Offset (m+4)
This function always subtracts the digital offset set value from the indicated value.
This function is convenient when zero cannot be obtained with no load for some reason or for
offsetting. When not using, set "00000".
(Setting range -30000 to +30000)

Measurement value and data update counter
The F130 performs A/D conversion at a rate of 3000 times/sec to calculate the measurement value.
Each time the measurement value is updated, the data update counter is incremented by one. Since
the measurement value and counter value are returned in pairs, how often you see the measurement
data of the F130 can be known from the progression of the counter value.

< About average value measurement time >
What can be specified as a section for average value hold detection is up to 10
seconds (average count: 30000). Even if the hold request bit is ON exceeding
that time, the average value in 10 seconds is held.
Point
< About the request bit delay times (t1 to t3) >
Since the delay times change depending on the system environment, sufficient
evaluation should be performed before use in response to the actual status of use.
