Warning● Before using a new instrument or exchanging the strain gage applied
transducer for a new one, be sure to make calibration.
If calibration shall not be made, correct measured results may not be
obtained nor it may cause malfunction in the instrument and there
may exist damage to the peripheral equipment.
Besides, even though the calibration has been made, there may occur
the similar case when the result is not correct, so make calibration
again.
● During the calibration is executing, be sure to make available for the
calibration set (Setting “00000” on F−97). Tare weight cancellation
clear, and to make cancellation (Setting of F−98) for compensated
data on zero set and set the OFF position of Zero tracking(Setting “
00000” on F−08 and F−09). If neglected, it returns the error
command (Error command No.01) to the host.
● The error command (Error command No.02) similarly returns to the
host when the command not suitable for the procedure is transmitted
during the calibration.
● Please match function No.F−50 to F−59 as to the communication to
host’s specification and change (Refer to the paragraph 8, 9−3 and

procedures, we’ll explain some conditions to execute actual calibration here.
(1) When executing calibration on the new instrument.
(In case that our combined inspection 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 5−4−1(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 5−4−1(2)
D When load condition is clarified, but output condition of load cell is unclear.
→Proceed to the paragraph 5−4−1(3)
D When exchanging with existing CSD−815 is required.
→Proceed to the paragraph 5−4−1(4)
(2) When making calibration again.
D When calibration only for tare weight is required.
(In case that our combined inspection has already executed, and the calibration
only for tare weight is required.)
D When fine adjustment on zero and span is required.
5−4−1. 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 5−4−1
(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.
77
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 weight1.5 t
Weighing capacity5 t
Maximum display5 000
1
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.
(Output of load cell at maximum display)

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. (When the calibration by communication is required, execute it
according to the paragraph 5−3−1.)
3
If necessity requires, apply zero/span fine adjustment according the paragraph 5−2−4, and
5−2−5. (When the calibration by communication is required, execute it according to the
paragraph 5−3−4 and 5−3−5.)
(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.

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. (When the calibration by
communication is required, execute it according to the paragraph 5−3−3.)
3
If necessity requires, apply zero/span fine adjustment according the paragraph 5−2−4, and
5−2−5. (When the calibration by communication is required, execute it according to the
paragraph 5−3−4 and 5−3−5.)
(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.
1
Set the instrument in the monitor mode according to the paragraph 7−18. 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 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.
(Load cell output at the time of the maximum display)
=(Load cell output at the weighing application)−(Load cell output at the initial load)
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
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. (When the calibration by communication is
required, execute it according to the paragraph 5−3−1 and 5−3−3.)
79
7
As necessity requires, make fine adjustment on Zero and Span according to the paragraph
5−2−4 and 5−2−5. (When the calibration by communication is required, execute it according
to the paragraph 5−3−4 and 5−3−5.)
(4) When replacing the existing CSD−891B 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 5−4−1(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−891B, 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 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−891B.
2
According to the paragraph 4, replace the exiting CSD−891B with a normal instrument and
make connections.
3
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. (When the calibration by
communication is required, execute it according to the paragraph 5−3−2.)
80
5−4−2. When the calibration is executed again
When purchasing a new instrument and our combined inspection has executed,
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 our combined inspection has completed and calibration on only tare weight is
required.)
When the initial load (tare weight) has changed after completing the calibration, or when our
combined inspection 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.
1
After setting the initial load (tare weight) on load cell section, execute calibration according to
the paragraph 5−2−6.(When the calibration by communication is required, execute it
according to the paragraph 5−3−6.)
(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). (When the calibration by communication is required, execute it
according to the paragraph 5−3−4. (Fine adjustment on zero) and 5−3−5. (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.
