5. Calibration procedures
Warning
● Before using the new instrument or after exchanging the strain gage
applied transducer with a new one, be sure to make calibration.
If calibration is not made, correct measured results may not be
obtained, or it may cause malfunction to the instrument and it may
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.
5−1. Preparations
According to the Chapter 4. Connecting method, connect the instrument and the strain gage
applied transducer properly, then supply the power.
5−2. Calibration procedures
Load calibration procedures for the instrument are as follows:
1
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).
2
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).
3
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.

procedures, we’ll explain some conditions to execute actual calibration here.
(1) When executing calibration on the new instrument.
(In case that Combined Inspection at Minebea 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.)
→Proceed to the paragraph 5−3−1(1)
D When load condition and output condition of load cell are clarified.
(Required accuracy is more than 1/1 000 or so.)
→Proceed to the paragraph 5−3−1(2)
D When load condition is clarified, but output condition of load cell is unclear.
→Proceed to the paragraph 5−3−1(3)
D When exchanging with existing CSD−702 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.
40
For 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
5t
Maximum display

Calculate the output of load cell at maximum display from the above conditions. Check that
1
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.
3
If necessity requires, apply zero/span fine adjustment according the paragraph **タグなし**,
and **タグなし**.
(2) When the both conditions of load and the output of load cell are clarified.
(In case that required accuracy is more than 1/1 000 or so.)
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.

After making the load cell to the initial load condition (tare weight), execute the calibration
according to the paragraph **タグなし**. In this case, input “5000” in the step 6, and input
the load value applied on the load cell in the step 8 individually.
3
If necessity requires, apply zero/span fine adjustment according the paragraph **タグなし**,
and **タグなし**.
(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.
1
Set the instrument in the monitor mode according to the paragraph 7−14. 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.
2
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.
3
Record the display value on load display section after applying 5 t load on the load cell section.
This value is the output of load cell with weighing capacity applied.
4
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)
5
Quit the monitor mode of the instrument.
6
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
**タグなし**. 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.
7
As necessity requires, make fine adjustment on Zero and Span according to the paragraph
**タグなし** and **タグなし**.
42
(4) When replacing the existing CSD−702 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−702, 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).
1
According to the paragraph ****, 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−702.
2
According to the paragraph 4, replace the exiting CSD−702 with a normal instrument and
make connections.

The comparator in the instrument, S1 and S2 can select the operation whichever “open
collector ON at more than the set value”, or “open collector ON at less than the set value”. This
selection can be made in the Function mode. (Related function F−32)
As for default, the “open collector ON at more than the set value” is selected for both of S1 and
S2.
Warning
● Depending on the operational selection for comparator, ON/OFF
condition for each open collector output may differ. If wrong operation
is selected, ON/OFF condition for open collector output becomes
inadequate and it may cause an unexpected accident due to
malfunctions on peripheral instruments, so care should be taken fully.

7−2−5. Hysteresis on comparator
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 open collector output may differ. If wrong mode is selected,
ON/OFF condition for open collector output becomes inadequate and
it may cause an unexpected accident due to malfunctions on
peripheral instruments, so care should be taken fully.
The operation of judgement display panel and the open collector output when the hysteresis of
the comparator is set is shown as an example of S1 below.

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.
The digital filter for the instrument can be set from “00000” to “00004”.
The averaged−out times of digital filter can be decided from the set value (Related function
F−04)
As for default, “00003” is selected.
The relations between the setting and the averaged−out times are as follows:
(Averaged−out times)=2n
n:Set value
For example, when “00004” is selected, averaged out times is as follows:
(Averaged−out times) =24
=16(Times)
The tendency to the characteristic by the leveling frequency is shown in the table below.:

7−4. 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.
7−4−1. 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.
7−4−2. 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]
=2m
For example, when the setting of function F−15 is “00002”,
=22
[Stabilized filter times]
=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]=24×22
=16×4

7−6−1. Selection of target of display
The instrument can select the display frequency from 4 times/s and 20 times/s. This selection is
done in the function mode (related function F−03). Default has selected 4 times/s.

● The comparator of the instrument executes comparative operation
synchronous with the display. Besides, the conversion of analog
output is synchronous with the display.
In due course, when changing of conversion times of comparator, and
also conversion times of analog output is/are required, execute the
change of display times with the function F−03.
7−6−2. Selection of position of decimal point display
The instrument can display the decimal point at the “Load display section” of the instrument.
The selection of display can be made in the Function mode. (Related function F−01) Default has
selected “No decimal point display”.
7−6−3. Load display range
The load display range for the instrument is fixed from the −10 % to 110 % of the maximum
display value at the time of setting during calibration. When less than the range, “−OL”
displays and over the range “OL” displays. For example, when the maximum display value is
“1 000”, the load display range will be from −100 to 1 100.
Besides, when under −100, the “−OL” displays, and over 1 100, the “OL” will display.
7−7. Selection the target for HOLD
The instrument can select the target for HOLD function among “load display”, “open collector
output of comparator S1 and S2, LED display”, “Analog output” and “Options”.
This selection can be made in the Function mode(Related function F−10).
As for the default, “All is selected.” Layout of setting for the F−10 are as follows:
100 digit:Load display
101 digit:Open collector output of comparator S1 and S2, LED display
102 digit:Analog output
103 digit:Optional output
