5. Calibration
This indicator, converts an input voltage from a load cell to the "mass" value, and
displays it. Calibration is the adjustment function so that the scale (indicator) can
display the weight correctly.
5.1. Items of Calibration Mode
There are four items in the calibration mode.
How to enter the calibration mode:
In the weighing mode, press the CAL key which is located behind the sealing panel.
Cal in
is displayed for 2 seconds and then
Cal 0
will appear. Use the MODE key to
select an item and use the ENTER key to execute it.
NOTE: Calibration could be started by simultaneously pressing the
ZERO
and
TARE
keys, instead of the CAL key. The procedure is prohibited when the indicator
has received a certified approval.
Items Required to be Performed
Cal5et
Sets capacity, resolution, decimal point position and display format,
weighing range and unit. These items should be set first in order for the
indicator to function as a weighing instrument. Set values do not need to
be changed again unless the indicator itself is replaced. For details, refer
to “5.2.1. Configuring a Weighing Instrument”.
Cal 0
Calibrates zero and span. This is required after installation, to get accurate
data. For details, refer to “5.2.3. Zero Calibration” and “5.2.4. Span
Calibration”.
Optional Items to be Performed as Necessary
lnr 0
Performs digital linearization. Refer to “5.4. Digital Linearization
Function”.
g 5et
Compensates for acceleration of gravity.
Refer to “5.5. Gravity
Compensation Function”.
Gravity compensation function: Compensates for weighing error
between the calibration location and another weighing location using
gravity acceleration.
In the calibration mode, the keys have functions as follows:
0
-
9
Numerical
keys.
MODE
The key to display other items.
CLEAR
The key to restore the numerical value to the initial setting or to change the
parameters.
+/-
The key to display other parameters.
ESC
The key to proceed to the next step without changing set values.
ENTER
The key to store new calibration data and proceeds to the next step.
