damage the peripheral equipment.

Moreover, even if calibration has made, there may occur the similar

case as above when the result is not correct. So make precise calibration again.

● The calibration for the instrument and “Display value at the time of

minimum analog output”(F−21) and “Display value at the time of

maximum analog output” (F−22) are not interlocked. In due course,

make check on the setting for F−21 and F−22 securely. If neglected, correct outputs may not be obtained, or it may cause

malfunction to the instrument and it may damage the peripheral

equipment.

Calibration method to register the output (conversion with mV/V) of strain gage applied

transducer at the time of maximum display (weighing capacity) 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 load(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 the reading output of strain gage

applied transducer, when setting in the condition of zero load applied (Initial load application with tare) and in the condition of actual load applied individually.

→Proceed to the paragraph 5−3−1(3)

D When exchanging with existing CSD−701B is required.

→Proceed to the paragraph 5−3−1(4)

(2) When making calibration again.

D When calibration only for tare weight is required.

(In case that the combined Inspection at Minebea has already executed, and the calibration

only for tare weight is required.)

D When fine adjustment on zero and span is required.

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

When the new instrument is purchased or reuse is desired with the new specific conditions,

execute the calibration with whichever procedure as follows：

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

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

Warning ● The calibration accuracy obtained in this procedure is less than

1/1 000 or so. When precise accuracy more than 1/1 000 is necessary,

make calibration with actual load according to the paragraph 5−3−1

(2).

Besides, the accuracy described here is a combined accuracy of the

instrument and the strain gage applied transducer connected. 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.

● The rated output value for load cell applicable by the calculation

should be assumed as the value described on the “Inspection data”

individually.

5−2−1For example, we will show the calibration procedures as follows, 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 0.4 mV/V to 3.1 mV/V. If the value is out of the range, calibration can’t be executed.

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

according to the paragraph 5−2−1. In this case, input “5000” in the step 6, and input “1.0000”

in the step 8 individually.

If necessity requires, apply zero/span fine adjustment according the paragraph 5−2−4, and

5−2−5.

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, the total accuracy of these. If high accuracy is required, full considerations should be made on each factor. If

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

obtained, so care should be taken fully.

When high accuracy is required, actual load calibration by using 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 cell 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 the maximum display from the above conditions.

Check that the calculated value at this point is within the range from 0.4 mV/V to 3.1 mV/V. If the value is out of the range, calibration cant’ be executed.

according to the paragraph 5−2−3. In this case, input “5000” in the step 6, and input the load

value applied on the load cell in the step 8 individually.

If necessity requires, apply zero/span fine adjustment according the paragraph 5−2−4, and

5−2−5.

(3) When the load condition is clarified but the output condition of load cell is not clarified.

In the case of using the existing load detecting section, and adopting the new digital indicator only, it is necessary to execute calibration after checking the output of load cell when its

output is not clarified. For example, followings are calibration procedures when weighing capacity is 5 t and the others are not clarified.

Set the instrument in the monitor mode according to the paragraph 7−19. In this condition,

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

3.100 0 with the unit of mV/V.

After making the load cell section to the initial load condition (tare weight), record the display

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

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

value is the output of load cell with weighing capacity applied.

4. 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 the calculated value is within the range from 0.4 mV/V to 3.1 mV/V. The 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, “5000” in the step 5 and another input is the value of

“Output of load cell at the maximum display” calculated from the ④ in the step 8. 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 6 and also input “Load value going to

apply on load cell” in the step 8 individually.

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

5−2−4 and 5−2−5.

(4) 5−3−1When replacing the existing CSD−701B 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 the actual load according to the paragraph 5−3−1(2).

Moreover, the accuracy described here is a combined accuracy with the

instrument and strain gage applied transducer connected. When another error factors may exist, such as constructional error

factors or so, it will become out of warranty for accuracy, so care

should be taken fully.

When the load at the section of load cell can’t make it with initial load application due to failure on the existing CSD−701B, execute calibration by referring to the procedures as below.

However, in case that the initial load condition can be obtained, make calibration according to the procedures of (1) and (2).

According to the paragraph 8−1, read out and write down the function F−90 “Increment

value”, the F−91 “Maximum display value”, the F−93 “Zero calibration value”, and the F−94

“Span calibration value” in the existing CSD−701B.

According to the paragraph 4, replace the exiting CSD−701B with a normal instrument and

make connections.

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

5−2−2. In case of this, input the “Increment value” recorded at ① in the step 3, the

“Maximum display value” in the step 5 and the “Zero calibration value” in the step 7 and in

the same way, input “Span calibration value” in the step 9.

5−3−2. When the calibration is executed again.

When purchasing a new instrument and the combined inspection has executed at Minebea,

however, the tare weight has changed, or fine adjustment on zero and span are required, make

calibration with whichever the following methods.

(1) Calculation on tare weight only

(When combined inspection has completed at Minebea and calibration on only tare weight is

required.)

When the initial load (tare weight) has changed after completing the calibration, or when the

combined inspection at Minebea has been made and the calibration only for the initial load(tare weight) is required after the installation, proceed the calibration in the following steps.

After setting the initial load (tare weight) on 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).

Warning ● The accuracy obtained through the calibration procedures consists

from combined accuracy with the instrument and 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 factor. If neglected, there will be a case that the desired accuracy

shall not be obtained.

Comparator S1 and S2 of the instrument can set the hysteresis because of the chattering prevention of the output relay. Hysteresis can be used by combining setting by the width of data and combining setting by the time width. Moreover, effective directions of hysteresis can be selected from either ”Off delay” or

”On delay”.

These selections are done in the function mode (related function F−34, F−35, and F−36).

Default has set hysteresis “OFF”.

Warning ● Depending on the setting of comparator hysteresis, ON/OFF condition

for each contact output may differ. If wrong mode is selected, ON/OFF

condition for contact output becomes inadequate and it may cause an unexpected accident due to malfunctions on peripheral instruments,

so care should be taken fully.

7−3. How to use the filter

The instrument has the digital filter to which the data converted into digital is stabilized by the calculation processing.

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

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

fully.

7−3−1. Digital filter

The digital filter for the instrument can be set from “00000” to “00007”.

The averaged−out times of digital filter can be decided from the set value (Related function F−04) As for default, “00004” is selected.

The relations between the setting and the averaged−out times are as follows：

(Averaged−out times)＝2

For example, when “00004” is selected, averaged out times is as follows：

(Averaged−out times)＝2

The tendency to the characteristic by the leveling frequency is shown in the table below.：

7−4. Zero tracking

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

 ● Effective only when the A/Z mode is selected. (Related function

F−70)

7−4−1. What is zero tracking?

D Zero tracking is a function to cancel the slow drift of zero within the constant conditions,

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

D When the data variation within the set time with function F−09 is within the set value set

with the function F−08 against the zero point, then the input will be cancelled as the zero

point. However, when the zero point compensation for the total “±10 % of the maximum

display value” at the zero tracking and zero set are completed until that time, the further directional zero tracking will not executed.

7−4−2. Setting related with zero tracking.

D Set the data width that performs zero tracking with the function F−08. The zero tracking

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

below formula.

(Zero tracking data width) ＝(Set value of F−08)×0.5×(Increment value for display)

For example, when the setting of function F−08 is “00010” and the increment value for

display is “D=5”, then (Zero tracking data width) will be as follows:

(Zero tracking data width) ＝10×0.5×5

＝25D

D Set the time width performs zero tracking with the function F−08.

 ● The zero tracking will not operate whichever the function F−09 or the

function F−70 is set as “0”, or the function F−70 is “0”.

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

the zero tracking.

● When the variation of load display becomes moderate due to the

strength/weakness of the digital filter and stabilized filter, there may

have the case that the zero tracking becomes effective even when the

actual load variation is rapid, so care should be taken fully.

7−4−3. Cancellation for compensation by zero tracking

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

 ● When changing the target for zero tracking is required, be sure to

cancel the compensated portion by zero tracking once using the

function F−98.

The zero tracking of the instrument will become effective at the time of the load display will be

the gross weight. In due course, at the time of A/Z ON, the zero tracking will not work.

7−5. Stabilized filter

The instrument prepares the Stabilized filter that can filter through digital filter strongly when variable width for load is within the constant value and also the same condition is frozen for more than a constant period.

7−5−1. What is the Stabilized filter?

When the variable width of load is within the set value by the function F−17 and also the same condition is frozen for more than the set value with the F−16, the digital filter for stabilized

filter will become effective set with the function F−15. That is, the digital filter will be applied only when the load is stable for more than a constant value, and then stabilizes the load display.

7−5−2. Setting related with the Stabilized filter.

D Set the data to apply the Stabilized filter with the function F−17. The stabilized filter

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

following formula.

[Stabilized filter data width]＝[Set value of F−17]×[Display increment value]

For example, when the setting of function F−17 is “00010” and the display increment is

“D=5”, then

[Stabilized filter data width]＝10×5

＝50

D Data width supervisory time for the Stabilized filter can be set with the function F−16.

D The digital filter for Stabilized filter can be set with the function F−15.

D The averaged−out times for the digital filter for Stabilized filter per set value “m” can be

obtained by the following formula.

[Stabilized filter averaged−out times]＝2

For example, when the setting of function F−15 is “00002”,

[Stabilized filter times]＝2

＝4(Times)

D Moreover, when the digital filter has set with the function F−04, the averaged−out times

will be “Stabilized filter averaged−out times” and “Averaged−out times” with the function

F−04. (Refer to the paragraph 7−3.) That is,

[Averaged−out times] ＝[Averaged−out times with the F−04]×[Averaged−out times of stabilized filter]

For example, setting for the function F−04 is “00004” and the function F−15 is “00002”

as well, it will be as follows:

[Averaged−out times]＝2

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

lights up), zero set will not be accepted. It will display “ER−5”.

When zero set is desired to execute, execute after making the Tare

weight cancellation clear (A/Z OFF).

7−13. Lock of key function

The instrument prepares the lock of key function.

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

executes lock ON of key funciton by setting each digit=1. As for default, “all is lock OFF of key

function”. Besides, the correspondence between the target of key funciton and setting digits are as

follows:

digit ：ON/OFF of CHECK value(Press the  key in the condition of pressing the

 key.)

digit ：ON/OFF of Peak Hold function, A/Z ON(), Reset of the peak value,
