● Install the F331 as far away from devices generating high frequency, high voltage, large

current, surge, etc., as possible. Also, carry out wiring separately from their power lines. Do not carry out parallel wiring and common wiring.

● Do not use it, when it is broken down.

● Tighten the screws for the screw type terminal block at the specified torque.

　If they are loose, shorts, fire or malfunctions may occur.

Tightening torque: 0.2 to 0.6 N •m

● For sensors, external inputs/outputs and options, use shielded cables.

● For turning on/off the power, be sure to keep intervals of 5 seconds or more.

● After power-on, make sure to warm up the F331 for at least 30 minutes or more before use.

● If the F331 is not used by the specified method, its protective performance may be impaired.

● Maintenance

- When performing maintenance, disconnect the power.

- Do not wipe with a wet rag, or with benzine, thinner, alcohol, etc. Doing so may cause discoloration or deformation of the F331. In the case of heavy contamination, wipe off

the contamination with a cloth after dipping it into a diluted neutral detergent and squeeze it well, and then wipe with a soft, dry cloth.

● Although packing at factory has been considered as shocks can sufficiently be absorbed,

breakage may result if shocks are applied when the spacers are reused for transportation. If you send the F331 to us for repair, etc., take adequate measures against shocks by using

polyurethane materials, etc., separately.

● If you dispose of the product, handle it as industrial waste.

4　HOW TO CALIBRATION

4 HOW TO CALIBRATION

A data sheet will be attached to a strain gauge sensor you buy.

On the data seat, the following values are listed.

Capacity .................... Load (unit: kg, t, etc.)

Rated Output............. Voltage (unit: mV/V)

Non-Linearity, Hysterisis, Input Resistance, Output Resistance,

Zero Balance, etc.

The Capacity and the Rated Output are necessary values for the equivalent input

calibration. Input these two values to F331.

Point

"Calibration" refers to an operation whereby matching between the F331 and a strain gauge sensor

is obtained. The F331 uses the calibration methods as described below.

◇Zero calibration

Check around the strain gauge sensor for unwanted loads such as foreign object is placed or there is

contact with peripheral equipment.

Chapter

HOW TO CALIBRATION

◇Equivalent input calibration

This approach uses no actual loads but setting of the rated output value of the strain gauge sensor

(mV/V) and the rating value (value to be displayed).

This method is simple and employed when actual loads cannot be applied.

For example

Gain will be automatically decided by registering the values indicated as follows:

For load: 2.001mV/V - 100.0kgf

For pressure: 2.002mV/V - 10.00kgf/cm2, and

For torque: 2.502mV/V - 15.00kgf.m.

◇Actual load calibration

This approach provides calibration by applying an actual load to the strain gauge sensor and setting

the actual load value. This calibration is without little errors and more correct.

By setting hysteresis, cha ttering can be prevented in such a case as subtle fluctuations of signals.

HI limit

OFF ON

The hysteresis value may be determined so as to allow a margin for timing the turning off of the HI/

LO limit comparison. Normally, it is turned on when the indicated value exceeds the HI limit and is

turned off when the indicated value falls below it. However, by setting the hysteresis, it is turned off

when the indicated value falls below the HI limit further lowered by the hysteresis value. This

function is effective to prevent chattering in such a case where signals fluctuate (vibrate) subtly.

SETTING OF FUNCTIONS

5-5. Digital offset

This function subtracts a set value from the indicated value. If you make digital offset , the value

which is obtained by subtracting the set value from the indicated value will be displayed. This is

convenient when you cannot obtain zero by unloading the equipment for some reason or when you

want to give offset.

(Indicated value to be displayed) = (Actual indicated value) - (Digital offset setting value)

5-6. Moving average filter

This function restrains the indicated value from fluctuating by moving-averaging the A/Dconverted

data. The moving average times can be selected in the range of OFF (1 time) - 512 times. With an

increasing number of moving average times, the indicated value becomes more stable, while the

response becomes slower. On the other hand, with a decreasing number of moving average times,

the response becomes faster, while the indicated value becomes easier to fluctuate.

(external judging input is ON when hold mode is OFF).

5-7. Digital low pass filter

This low pass filter cancels undesired noise components by filtering the A/D-converted data. Set

the cutoff frequency like a low pass filter in an analog circuit. The cutoff frequency can be selected

from 3, 6, 12Hz. Select an optimum value according to the type of measurement and setting

■About error response

If there is any problem with request from the master, each slave will not execute the command but

return error response. In function code, the value of the requested function code + 0x80 is used.

Exception code judgment is made after the received frame.

The order of priority of exception code judgment is 1→3→2.

Exception code No.

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.

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.

Sensor rated capacity value is preset to “0”. Select a proper non-zero value.

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.

Strain gauge type sensor output is outside the F331’s allowable sensor input range. Check if the sensor is properly loaded, and the its rated output falls within the F331’s sensor input range. Perform Span calibration again. Then, perform Span calibration again.

Invalid ZERO key operations.
