with mV/V) of strain gage applied transducer at the time of maximum display (weighing value)

after setting the load to zero (Initial load condition with tare weight).

Calibration method (Automatic calibration for Zero and Span) to register the output of strain

gage applied transducer (conversion with mV/V) at the time of zero(Initial load application

with tare) at the optional load condition, and also to register the output (conversion with

mV/V) of strain gage applied transducer at the time of maximum display (weighing capacity).

Calibration method (Actual load calibration) to register by reading output of strain gage

applied transducer, when setting in the condition of zero load (Initial load application with

tare) and in the condition of actual load applied individually.

Fine adjustment on Zero

Fine adjustment on Span

Calibration procedures to apply registration again for zero point only(Tare weight

has not executed.)

D When load condition and output condition of load cell are clarified. (Required accuracy is

less than 1/1 000 or so.)

D When load condition and output condition of load cell are clarified.(Required accuracy is

more than 1/1 000 or so.)

D When load condition is clarified, but output condition of load cell is unclear.

D When exchanging with existing CSD−581−15 is required.

(2) When making calibration again

DWhen calibration only for tare weight is required.(When our combined inspection has already executed, and calibration only for tare weight is required.)

DWhen fine adjustment on zero and span is required.

5−3−1. In case of executing the calibration on new instrument.

When the new instrument is purchased or re−use is desired with the new specific conditions,

execute the calibration with whichever method as follows:

(1) When load condition and output condition of load cell are clarified.

(In case of desired accuracy is less than 1/1000 or so.)

Warning ● The calibration accuracy in this procedure is less than 1/1 000 or so.

When precise accuracy more than 1/1 000 is required, make

calibration with actual load according to the paragraph 5−3−1(2).

Besides, the accuracy described here is combined accuracy of the

instrument and the strain gage applied transducer to be connected

with. If there may exist another factors of error such as mechanical

elements and so on, it will become out of warranty, so care should be

taken fully.

● Rated output value for load cell applied on calculation should be the

same value are described on the “Inspection data” individually.

For example, we will show the calibration procedures in the following procedures, that is, 3

points of load cells with 3 mV/V of rated output and 5 t of rated capacity.

Tare weight 1.5 t

Weighing capacity 5 t

Maximum display 5 000

Calculate the output of load cell at maximum display from the above conditions.

Check that the calculated value should be within the range from 0.2 mV/V to 3.1 mV/V.

If the value is out of the range, calibration can’t be executed.

calibration works, that is , total accuracy of these. If high accuracy is

required, full considerations should be made on each factors. If

neglected, there will be a case that desired accuracy shall not be

obtained.

When high accuracy is required, actual load calibration by the weight and so on are required.

For example, we’ll show the calibration procedures in the following conditions, that is, 3 points

of load cells with 3 mV/V of rated output and 5 t of rated capacity.

Tare weight 1.5 t

Weighing capacity

As necessity requires, execute fine adjustment on Zero and Span according to the paragraph

5−2−4 and 5−2−5.

(3) When load condition is clear, but output condition of load cell is unclear

In the case of using the existed load detecting instrument, and only adopting this digital

indicator newly, it is necessary to execute calibration after checking the output of load cell of

which output is not clarified.

For example, following are calibration procedures when weighing capacity is 5 t and the others

are not clarified.

Set the instrument in monitor mode according to the paragraph 7−15. In this condition, the

output level of load cell connecting with the instrument can be monitored up to X.XXXX with

the unit of mV/V.

After making the load cell to the initial load condition(tare weight), note the display value on

load display. This value is output of load cell at the time of initial load condition.

Note the display value on load display after applying 5 t load on the load cell section.

This value is output of load cell on the condition of weighing capacity.

From the load cell output at the time of initial load application recorded at ②, and load cell output recorded at ③ at the time of application of weighing capacity, output of load cell at the

time of maximum display can be calculated according to the below formula.

Check that this calculated value will exist within the range from 0.2 mV/V to 3.1 mV/V.

Calibration can’t be executed if the value is out of the range.

（Output of load cell at the time of maximum display）＝(Output of load cell at weighing capacity) − (Output of load cell at initial load application)

Quit the monitor mode of the instrument.

After making the load cell to the initial load condition(Tare weight), execute calibration

according to the paragraph 5−2−1. In this case, the accuracy is less than 1/1 000 or so.

At this moment, input each value that one is “5000” in the step 5 and another is the value by

“Output of load cell at maximum display” calculated by ④ in the step 7. If the accuracy more

than of 1/1 000 or so is required, execute calibration according to the paragraph 5−2−3.

And at the same time, input “5000” in the step 5 and “Load value to be applied on load cell” in

the step 7 individually.

As necessity required, make fine adjustment on Zero and Span according to the paragraph

5−2−4 and 5−2−5.

(4) In case of replacing the existed CSD−581−15 with a new one

Warning ● The accuracy in this procedure is less than 1/1 000 or so.

If higher accuracy is required, make calibration by using actual load

according to the paragraph 5−3−1(2). Moreover, the accuracy

described here is a combined accuracy with the instrument and

connected strain gage applied transducer. When another error factors

may exist, such as constructional error factors or so, it will become

out of warranty of accuracy, so care should be taken fully.

When the load at the section of load cell can’t make it initial load application due to failure on

the existing CSD−581−15, execute calibration, execute calibration by referring to the

procedures as below. However, when initial load condition can be obtained, make

calibration according to the procedures of (1) and (2).

According to the paragraph 8−1, read and note the “Increment value” of Function F−70,

“Maximum display value” of F−71, “Zero calibration value” of F−73, and “Span calibration

value” of F−74.

According to the paragraph 4, replace the exiting CSD−581−15 with a normal product and

make connections.

After turning ON the normal instrument, make calibration according to the paragraph

5−2−2. At the same time, input each “Increment value” noted at ① in the step 3, “Maximum

display value” in the step 5 and “Zero calibration value” in the step 7 and in the same way,

input “Span calibration value” each.

5−3−2. In case of executing re−calibration

When purchasing the new instrument, and also executing our combined inspection,

Tare weight has changed, fine adjustment on zero and span are required, make calibration with

whichever method as follows:

(1) Calculation on tare weight only

（When

Though calibration has completed, initial load (tare weight) has changed, or our combined

inspection is made and calibration only for the initial load(tare weight) is required

after installation, make calibration according to the following procedures.

After setting the initial load (tare weight) for load cell section, execute calibration according to

the paragraph 5−2−6.

(2) In case of executing fine adjustment on zero and span

Make adjustment according to the paragraph 5−2−4（Fine adjustment on zero), and 5−2−5

(Fine adjustment on span).

our combined inspection has completed and only calibration on tare weight is

required.)

Warning ● The accuracy obtained through the procedures of this calibration

consists from combined accuracy with the instrument and combined

strain gage applied transducer, the accuracy of weight used during the

calibration, error factors on mechanical and also error factors on

calibration works, that is , total accuracy of these. If high accuracy is

required, full considerations should be made on each factors. If

7−3. How to use filter

The instrument prepares digital filter that can stabilize transferred data into digital through

processor.

Warning ● When setting filter is not adequate, correct measurement can’t be

made and it may cause unexpected accident, so care should be taken

fully.

7−3−1. Digital filter

The digital filter in the instrument can be set from “00000” to “00077”.

Averaged−out times of digital filter can be decided from the set value (Related function F−04).

As for default, “00033” has set. The relations between setting and average−out times are as

follows:

(Averaged−out times)＝2

For example, when the setting is “00033”, averaged−out times are as follows :

(Averaged−out times)＝2

Characteristics tendency due to averaged−out time is listed as below:

7−4. Zero tracking

The instrument prepares zero tracking function in order to compensate for slow drift of zero.

7−4−1. What is zero tracking?

D Zero tracking is a function to compensate slow drift of zero within the constant condition,

and also to follow the zero point of the instrument in order to stabilize zero point.

D When data variation width within the set time with Function F−08 is within range of set

value set with F−07 against zero point, then the input will be cancelled as zero point.

7−4−2. Setting related with zero tracking

D Set the data width that perform zero−tracking with F−07. Zero tracking data width per

setting value “n” will be obtained by the calculation of display according to the below

formula.

[Zero tracking data width]＝[Set value for F−07]×0.5×[Display increment value]

For example, when the setting of F−07 is “00010”, and display increment is “D=5”

[Zero tracking data width]＝10×0.5×5

＝25D

D Set time width to perform zero tracking with Function F−08.

 ● Zero tracking will not operate whichever Function F−07 or F−08 is

set to “0”.

 ● When the load shows slow variations in the vicinity of zero, never use

zero tracking.

7−4−3. Target of zero tracking

Zero tracking of this instrument can select the target from “Gross weight” or “Net weight”.

This selection can be proceeded by the Function mode(related function F−62).

Default setting is “Gross weight”.

7−4−4. Cancellation for data compensation by Zero tracking

Cancellation for data compensated by zero tracking can be executed with the function F−98.

 ● To change the target of Zero tracking, be sure to cancel the data

compensated by Zero tracking at first with the function F−98.

7−5. Stabilizing filter

This instrument prepares Stabilizing filter that can filter through digital filter strongly when

variable width for load is within the constant value and also when the condition is frozen for more

than a constant period.

7−5−1. What is stabilizing filter?

As for stabilizing filter, when the variation width of load is within the value set by Function

F−97 and also when the condition is continued for more than the set period by the Function

F−10, the digital filter for stabilizing filter set by the Function F−09 will become effective.

That is, digital filter is applied only when the load is stable more than a constant value and also

stabilizes the load than before.

7−5−2. Setting related with stabilizing filter

D Set the data to apply stabilizing filter with the Function F−97. The stabilizing filter width

per set value “n” can be obtained through the display conversion by using the following

formula.

[Data width of stabilizing filter]＝[Set value of F−97]×[Display increment value]

For example, when the setting of F−97 is “00010” and display increment value is “D=5”,

it will be as follows:

[Data width of stabilizing filter]＝10×5

＝50D

D Supervisory time on data width for stabilizing filter can be set with the Function F−10.

D Set the digital filter for stabilizing filter with the Function F−09.

D Averaged−out times for digital filter for stabilizing filter per set value “m” can be obtained

by the following formula.

[Averaged−out times for stabilizing filter]＝2

m＋7

For example, when the setting for Function for F−09 is “00001”, it will be as follows:

[Times of stabilizing filter]＝2

1+7

＝256 times

Moreover, when digital filter has set with Function F−04, averaged−out times will become

“Averaged−out times of stabilizing filter” and also will be “Averaged−out times” with the

Function F−04. (Refer to the paragraph 7−3−1.)

That is,

[Averaged−out times] ＝[Averaged−out times with F−04]×[Averaged−out times for stabilizing filter]

For example, setting for F−04 is “00033”, and setting for Function F−09 is “00001”,

they will be as follows:

[Averaged−out times]＝2

7−6. Various kinds of functions related with display

7−6−1. Selection of target of display on load display

The load display on the instrument can select the target from “Net weight” and “Gross

weight”. These selections can be made in the Function mode. (Related Function F−02)

As for default, “Net weight” has been chosen.

Warning ● Depending on the selection of load display target, indication of load

display will differ when Tare weight cancellation (A/Z) function is

used. If wrong display target is selected, there may cause an

unexpected accident due to malfunction on peripheral equipment and

so on, caused by the mistake on load display.

7−6−2. Selection of target of HOLD

The instrument can select the target of HOLD by the combination with “Load display” and

“BCD output”.This selection can be made in Function mode. (Related Function F−50.)

As for default, “Selection of all”. The combination of setting of F−50 and the target of HOLD

will be as follows:

Setting of F−50

00000

00001

00002

00003

◯・・・HOLD ×・・・NO HOLD.

Load display BCD output

× × ○ × × ○ ◯ ○

Warning ● Even when only the display is target for HOLD, BCD output will be

frozen with the display together if the BCD output is interlocked with

display.

7−6−3. Range of load display

Load display range for the instrument is limited from −10 ％ to ＋110 ％ of maximum display

value which will be set during calibration. When it will be less than the range, display will show

“−OL” and if it will be over the range, display will show “OL”.

For example, when the maximum display value is 1 000, the load display range will become from

−100 to 1 100. Besides, display will show “−OL” under −100, and also will show “OL”

exceeding over 1 100.

7−7. Change of bridge power supply voltage

Warning ● Prior to change the bridge power supply voltage, set the power OFF

for the instrument. If neglected, there may cause unexpected failure.

The instrument can select bridge power supply from “10 V“ and “2.5 V”.

This selection can be made with the SW1 “Changeover SW for bridge power supply” located on the

board. (Refer to the below figure.) When the SW1 is changed to the left side, it will become 10 V

and to the right side, it will become 2.5 V. As for default, “10 V” has set.

When the instrument is applied in the system when zener barrier is used, be sure to select 2.5 V for

bridge power supply beforehand.

Warning ● When using the instrument in the system with zener barrier applied,

be sure to use it at 2.5 V of bridge power supply voltage.

If neglected, there may cause failure in the instrument. However, the

case when the instrument and strain gage applied transducer(s) are

connected with 4 cores shielded cable, is excluded.

Above explanation is the case when CAB−501(6 wires) for the cable and 350 Ω type for the load

cell are applied.

7−8. Tare weight cancelation (A/Z)

The instrument prepares Tare weight cancellation (A/Z) function.

Pressing the “A/Z A” key makes Tare weight cancellation (A/Z) function operated and when the

load display becomes net weight display, the “A/Z” lights up on the display and load display value

becomes “0” at the same time.

Moreover, when the “A/Z OFF Y” key is pressed, Tare weight cancellation (A/Z OFF) function will

activate and at the same time when the load display value becomes gross weight, the “A/Z” on the

status display will put off. Also, executing the Function F−98 makes the same work as Tare weight

cancellation clear (A/Z OFF).

7−9. Zero set

The instrument prepares zero set function.

When the display value on load display is within 10 % against the maximum display value (Refer to

the chapter 5.), pressing the “ZERO” key makes zero set function operated and the display will

show “0” compulsively.

However, zero set will not be accepted after total ±10 % of zero compensation is executed with zero

set. (ERR−0 display)

Also, the same operation can be made with the operation of “ZERO” at the input signal of external

control. Cancellation for data which applied zero compensation by zero set can be executed with

Function F−98.

 ● When tare weight cancellation (A/Z) is executed(during A/Z display

lights up), zero set will not be accepted. Display will show “ERR−5”.

When zero set is desired to execute, execute after Tare weight

cancellation clear (A/Z OFF) has been completed.

7−10. Digital Tare weight cancellation

The instrument prepares digital Tare weight cancellation function.

When known tare weight is included to the load going to measure, the tare weight can be registered

by the function previously and cancellation can be made.

When “Effective” for digital Tare weight cancellation is selected with the Function F−59, the Net

weight will be the value that comes from “Digital Tare weight cancellation value” subtracted from

“Gross weight”.

(Indication when digital Tare weight cancellation is effective.)

= (Gross weight)−(Digital Tare weight cancellation value)

(EX.)

D When measuring the vessel of 500 kg of self−weight on the platform scale of 2000 kg,

(“2 000” display with the load display of 2 000 kg) and only the display of contents weight of vessel is required, set the Function F−59 to be “0001” and also set the digital Tare

weight cancellation to be “Effective” and set the Function F−60 to be “00500”, then load

display will show “−500” without applying the vessel on the platform scale. (0 kg of load

condition) In due course, the load display shows “0” when empty vessel is applied.

 ● When Tare weight cancellation (A/Z) is executed in effective condition

of digital Tare weight cancellation, the display value will be shown as

follows:

(Indication when Tare weight cancellation in effective condition of

digital tare weight cancelation)

＝（Gross weight）−（Tare weight cancellation value)

7−11. Key lock

The instrument prepares key lock function.

With the Function F−06, each digit setting =0 execute key lock OFF , and each digit of setting =1

executes key lock ON. As for default, all are key lock OFF.

Besides, the correspondence between the target of key lock and setting digits are as follows:

digit：CHECK

digit：FUNC.

digit：ZERO

digit：A/Z OFF Y

digit：A/Z A

Moreover, when the “FUNC.” key is key locked , lock on “FUNC.” key will be cancelled only

once after the “FUNC.” key is pressed together with the “ENTER” key for more than 3 s.

7−12. CHECK value

When the “CHECK” key is pressed in the Measurement mode, CHECK value that are equivalent to

the set value with the Function F−43 will be ON. And at the same time when the “CHECK” on

status display lights up, the load value equivalent to the set value with Function F−43 will be

added to the load display value.

By pressing the “CHECK” key again, the CHECK value will be OFF and returns to the former

condition as it is. Moreover, when the CHECK value is ON, “RUN” output will be OFF and status

display of “RUN” will be put off, however, output of BCD will keep on outputting as same in the

Measurement mode.

 ● When the setting of Function F−43 is “00000”, load display value will

not vary even the “CHECK” lights up on the status display by

pressing the “CHECK” key. （Because the CHECK is 0.0mV/V.)

7−13. Memory position for setting data and so on

The instrument memories each data into RAM and EEPROM as follows:

Since the EEPROM is non−volatile, it will be stored almost indefinitely.

Also, RAM is charged by battery. Back−up life will be about 10 years when it is stored in the room

temperature.

Data memorized at RAM

D A/Z data A/Z OFF or data clear is possible with the execution of F−98.

D ZERO data Data clear is possible with the execution of F−98.

D Zero tracking data Data clear with the execution of F−98.

Data memorized at EEPROM

D FUNC data Possible to initialize data with the execution of F−99.

D Calibration data Possible to re−write by re−calibration.

7−14. Check mode

The following confirmations can be made in the Check mode.

00001＝10 00002＝10 00003＝10 00004＝10

00001＝Net weight (Interlocked with A/Z.) 00002＝Gross weight

00001＝20 times/s 00002＝50 times/s

D F−04 Setting digital filter

Initial value＝00033 Setting range：＝00000〜00077

※Select the average times for digital filter. When the figure grows larger, the

filter will become stronger, then effects from vibrations and so on are

scarcely shown on the display. Conversely, if too large figure is selected, the

response of variation of input sensor will become worse.

※Using the digital filter where vibrations and so on may exist is effective for

removing the deflection on the display.

D F−06 Setting key lock

Initial value＝00000 10

※Each “CHECK”, “FUNC.”,“ZERO”,“A/Z OFF Y” and “A/Z A” can be locked

individually. Key lock cancellation is made by setting “0”, and key lock is

made by setting “1”.

Moreover, when the “FUNC.” key is key locked , lock on “FUNC.” key will

be cancelled only once after the “FUNC.” key is pressed together with the

“ENTER” key for more than 3 s.

D F−20 Selection of target of BCD output

Initial value＝00002 00000＝Display

00001＝Net weight 00002＝Gross weight 00003＝External selection

※When “Display” is selected, BCD output interlocks with the display.

And when “Net weight” is selected, BCD output will interlock with the value

of “Net weight” at the time of executed tare weight cancellation and also

BCD output interlocks with “Gross weight” individually at the time of Tare

weight cancellation clear.

When “Gross weight” is selected, BCD output will interlock with the value

of “Gross weight”, whichever Tare cancellation is executed or not.

When “External selection” is selected, the target of BCD output can be

chosen among “Display”, “Net weight” and “Gross weight” through the

input of SEL1 or SEL2 at external control input.
