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 where setting should be done.
How to calibrate: In the 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 the
ENTER
key.
NOTE: Calibration could be started by simultaneously pressing the
ZERO
and
TARE
keys,
instead of the CAL key. However, in some cases, the procedures are altered to nullify
this option. Furthermore, this option is not available with sealed type version setting.
Required Items
Cal5et
Store capacity, resolution, alignment of 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. Setting 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 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 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 set values.
ENTER
The key to store new calibration data and proceeds to the next step.
CAL
The key to store all of the parameters into memory and display Caloff after
the calibration mode. Press the
ON/OFF
key to turn off the display.
