§４．Function４－１） Auto Zero
Pushing
button for 1 second in Measuring Mode, memorize the measured value at thismoment and set the measured value to zero. Afterwards display the increased or
decreased value from that moment as the Net value. (Subtract the memorized value fromthe Gross value). Unlike zero calibration, AZ can be operated within all the range of themeasured value. [AZ]LED is turned ON when AZ is operated.
After pushingbutton for 1 second in Measuring Mode, cancel AZ function and return to
the Gross value. [AZ] LED is turned OFF.
４－２） Preset Tare subtraction
After setting a preset tare value, always display the measured value which is subtracted thetare value. It is useful for a container which has a known weight beforehand.
A preset tare value becomes zero after zero calibration or span calibration has been done.
４－３） Zero Tracking
After fulfilling a condition of being a zero drift, set the Gross value to zero automati cally.
Condition of zero tracking: OFF, 0.5 to 10.0 scale division (0.5 step)Working time of zero tracking: 0.1 second, 0.5 to 5.0 second (0.5 step)
Zero tracking can be operated in the same range of zero calibration.
※Caution of using zero tracking
When loading the materials or ingredients into a large tank or scale, if the measured
value varies slowly within the range of preset condition of zero tracking, the measured
value keeps to indicate zero. In that case, please set the condition of zero tracking to‘OFF’.
４－４） Scale division
Scale division is a notch of displaying value and selected from 1, 2, 5, 10. Preset spanamount is not changed even if modifying a scale division.
Error occurs when resolution of span amount is not achieved with a preset scale division at
the time of span calibration. After span calibration has been done, please confirm a scale
division in Function Mode.
A quantitative value of comparator is set regardless of a scale division. But a comparator
works against the measured value which has a notch of a scale division.
４－５） Digital filer and Moving average
These functions make the measured value be stable when an external vibration is applied
to Load Cell or a sensor. It is more stable when the value of Digital filter or Moving averageis larger.
Strength of Digital filter:1 to 10, 1 step
Number of times of Moving average:1(OFF), 2, 4, 8, 16, 24, 32
When the value of Digital filter or Moving average is larger, response of indicating themeasured value is slower. Choose an appropriate value according to the nat ure of a signal
input from Load Cell or a sensor.

If the measured value is stable but need the fast response, there is one method of using a
condition of stop moving average. If the measured value exceeds the preset value of, stop moving average and make the response fast temporarily, and back to moving
average once the measured value decreases to be within the preset value of.
Condition to stop moving average: OFF, 0.5 to 10.0 scale division(0.5 step)

When selected ‘OFF’, it is kept on moving average.
４－６） Scaling of analog output (available when analog output OP-1,5 installed)
This is a function of scaling analog output 4 to 20mA or 0 to 10V against the preset value
set ator, regardless of zero or span of the indication value.
Analog output corresponds to Net value or Gross value selected at.
４－７） Button Lock
This function prevents wrong operation by means of disabling button input.
① Pushbutton for 2 seconds in Measuring Mode to lock the buttons
To unlock the buttons, Push
button for 2 seconds in the button locked status② Indicate
for 2 seconds when any button except
is pushed and ignore theinput.
４－８） Calibration Lock
This function prevents modification of calibrated span value from wrong operation bymeans of disabling span calibration.
① Keep pushingbutton while turning ON power or pushbutton 3 times
immediately after power ON to enter a mode of calibration lock.
② Pushorbutton to alternate to indicate a candidate as follows: Unlock calibration. Enable span calibration.
: Lock calibration. Disable span calibration.
③ Pushbutton to memorize the selected candidate.
Indicatewhen trying span calibration in calibration locked status and calibrated
span value is not modified.
In case this unit is assembled in a system and can’t be powered OFF, once enter Test Modeand push
button 3 times while displaying program version, occurred a forced reset andactivated as power ON. Push
button 3 times immediately and to enter a mode ofcalibration lock

５－２） Current Loop / serial output [OP-4]
This option is a serial interface dedicated for a TOYO’s peripheral equipment. If TOYO’s
CV-3010(serial to BCD converter) is connected to this interface, the measured value o f thisunit can be output as parallel BCD signal. Also an external indicator or a printer of TOYO canbe connected to this interface.
This interface is isolated from an inner circuit and connected to an external equipment through4 to 20mA current loop, thus less effected from noise and a cable can be extended up to 100m.
There is no function setting of this interface. Use a two wire cable and connect from output of
this unit to input of external equipment. Two wires can be connected whichever as there is nopolarity of them.
There is no use of a shielded cable in short distance, but wire apart from a power line or a drive
motor line with noise.

§７．Trouble shooting
If this unit is malfunctioning, please contact us if the problem cannot be solved by thefollowing measures. At this time, please inform us of the model name, product serial number,the malfunction symptoms and usage as much as possibl e. The model name of Load Cell or
sensor connected to this unit should be also informed.
７－１） Basic check point
1). Check the power supplied voltage. This unit is powered by DC24V
2). Check the wires connected correctly and firmly at the terminals of this unit
７－２） Cautions when calibrating1). Error occurs when calibrating zero point
To perform zero point calibration, Load Cell output with no load should be in the rangeof −2.8～+2.8mV/V. Please call us if the output with no load is out of range of±2.8mV/V, when u sing Load Cell whose rated output is more than 3mV/V.
2). Fluctuation of indication is large
The input sensitivity of this unit is 0.5μV/digit and indication resolution is 1/ 9,999 at
1.0mV/V input. Indication resolution is 1/5,000 at 0.5mV/V input. If the resolution is morethan this, fluctuation of indication becomes larger. In this case, please increase a scale
division atin Function Mode until not to be noticeable of fluctuation. Also digital filter
can ease fluctuation when the strength of it i s higher.
3). Error occurs when calibrating a span amount or displayed value is not correct as set inspan calibration.
This unit cannot measure in a system that the sum of initial tare value and measured value
exceed 3.3mV/V. Please contact us when the rat ed output of Load Cell or a sensor is morethan 3.3mV/V.
７－３） Countermeasures when an abnormal notice is indicated1). In case of measured value blinking when it is not over load status.
It is considered that a cable of Load Cell is disconnected or Load Cell has been failed.
Please confirm input signal (mV/V) from Load Cell in Test Mode.
７－４） Judgment whether this unit has malfunction1). Check the excitation voltage of Load Cell
Checking the excitation voltage between terminal No.1 (EXC+) and No.2 (EXC−) is stable
at 5V±0.25V. If it is not stable, a power supply circuit for Load Cell inside this unit may be
defective.
2). Short the output voltage of Load Cell (making an electric short between terminal No.3
(SIG+) and No.4 (SIG−)). In other words, the input voltage to this unit is made zero.
Check input voltage (mV/V) in Test Mode. Please confirm whether it is stable atabout 0.0000 mV/V. If it is not stable, this unit should have malfunction. If it isstable, please check Load Cell and a cable of it.
3). Digital I/O check
Check external input and output in Test Mode.
MA4-00218-R1- 19 -

７－５） Check Load Cell
Since Load Cell is composed of a bridge circuit, it is possible to make a rough judgement
by measuring the input / output resistance and insulation resistance.
＊ Please be sure to turn power OFF of this unit before checking Load Cell.
1). Failure judgement method by Load Cell resistance value.
① Remove all Load Cell cables.
② Measure the bridge resistance of Load Cell with a tester and check if there is any
abnormality in the input / output resistance.
2). Failure judgement method based on Load Cell insulation resistance① Remove all Load Cell cables.
② Measure the insulation resistance between shield and each cable of Load Cell at
voltage within 50V.
③ If the insulation resistance is 1000MΩ or more, Load Cell is mostly good.
