4-5 Repeatability Measurement
Repeatability measurement is a function that takes ten span measurements by placing and
removing weights and calculates the standard deviation of the measurement results. There
are two methods for repeatability measurement: Automatic Repeatability Measurement
(ARM) with internal weight or Semi-Automatic Repeatability Measurement (SARM) with
external weight. You can conduct stable measurements by adjusting the response speed
according to the measurement results.
4-5-1 Automatic Repeatability Measurement (ARM)
This function is only available for the LFR type.

Go to the function setting mode.
(Refer to Section 2-6 “Basics of Function
Settings.”)
Press and hold the [Function] key until “Func” is
displayed.
2
Set repeatability measurement to Automatic
Repeatability Measurement (ARM).
Press the [Function] key several times to select “F.ArM.”
Press the [Zero/Tare] key to select “1.”
3
Return to the weight display. Press the [Set] key.
The balance returns to the weight display.

Standard deviation
Press and hold the [Cal] key until “ArM” is displayed.
After a short time, the display changes to “Cnt.1”
and the measurement is started.
As the number of span measurements increases,
the number shown in “Cnt.*” increases to 1, 2, 3,
and so on. When the number reaches “10,” the
measurements are completed and the standard
deviation is displayed.
5
Return to the weight display. Press any key.
The balance returns to the weight display.
