(1) Procedure by key operation
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 may cause malfunction in the instrument and there may
exist damage in peripheral equipments.
Besides, even though 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 set Tare weight
cancellation clear, and to make cancellation (Execution of F−98) for
compensated data on zero set and set the OFF position of Zero
tracking(Setting “00000” on F−07 and F−08), and also set the OFF
position of Peak.
If neglected, correct measured results may not be obtained.
● During calibration procedures, press the key in case of
interrupting the calibration is required. The calibration data will be

(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.

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.

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

(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 7−19. 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.
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
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)

7−2−3. Operation on comparator S1 and S2
The comparator in the instrument, S1 and S2 can select the operation whichever “contact ON
at more than the set value”, or “contact ON at less than the set value”. This selection can be
made in the Function mode. (Related function F−32)
As for default, the “contact 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 contact output may differ. If wrong operation 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.
● When the load display is “OL” or “−OL”, the “display value” for the
comparison of comparator is assumed as “+∞(infinity)” and “−∞

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 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.
The operation of judgement display panel and the contact 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.
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

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.
58
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.
59
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
m
For example, when the setting of function F−15 is “00002”,
[Stabilized filter times]=2
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:

7−8−1. 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.
7−8−2. 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”.
7−8−3. 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.
7−9. Selection the target for HOLD
The instrument can select the target for HOLD function among “load display”, “comparator
contact output of S1 and S2, LED display”, “Analog output” and “Options”.
