22.Repeatability Check Function (GX-M series only
）
Repeatability is an indicator of variations in measured values when the same weight is repeatedly
loaded and unloaded, and it is usually expressed in terms of standard deviation (σ
n-1
).
The GX-M series has a built-in weight.
With the repeatability check function, the balance obtains 10 measurement data using the built-in
weight and displays its standard deviation.
By installing the balance and using this function, it is possible to check repeatability in the environment
where the balance is installed.
Note: This function is available for firmware versions 1.010 or later.
Ex. "Standard deviation = 10.0mg" means that the result of
repeated measurements of the same weighing material
falls within the range ±10.0mg at a frequency of about
68%.
1. Press and hold the SAMPLE key (for 4 seconds) in
the weighing display. After
rEp tE5t
is displayed,
release the key.
2. When
rEp tE5t
is displayed, data collection starts
automatically.
While data is being collected,
rEp
blinks.
To cancel, press the CAL key.
CANCEL
displays and you are returned to return to
weighing mode.
3. When data collection is completed, repeatability
(standard deviation) is displayed.
4. Press the PRINT key to output
repeatability (standard deviation).
5. Press the CAL key to return to
weighing mode.
Note
□
The results of this function differ from the repeatability conditions
of "28. Specifications" because it uses the weight of the balance
(about 850g), so treat it as a reference value.
□ In order to measure correct data, do not apply wind or vibration
while collecting data.
□ While using the password lock function, it can be used only when
logged in as
ADMIN
(administrator).
