5. Calibration

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:

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.
