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.
5.1.1. Items of Calibration Mode
There are four items in the calibration function in the procedure.
How to calibrate: In weighing mode, press the CAL key. After Cal in is displayed
for 2 seconds Cal 0 will appear. Then the required items should be selected and
displayed with the MODE key, then executed by pressing ENTER key.
NOTE: Calibration could be started by simultaneously pressing the ZERO and TARE key,
instead of CAL key. However, in some cases, the procedures are altered to nullify this
option. Furthermore, this option is not available with Stamping type version setting.
Required Items
Cal 5et
Store capacity, resolution, alignment of decimal point position and
display format, weighing range and unit. These items should be input
first in order for the indicator to function as a weighing instrument.
These parameters 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 (Sub-functions)
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 other 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 cancel key at inputting data, initial data and changing mode.
+/- The key to display other parameters.
ESC The key to proceed to the next step without changing them.
ENTER The key to store new calibration data and proceeds to the next step.
CAL The key to store all data into memory and display Caloff after the
calibration mode. And press the ON/OFF key to turn off the display.
