7. CALIBRATION
The AD-4530 measures voltage signals from sensors and displays the
values. Calibration is performed so that it performs correctly.
The decimal point (CF01), minimum scale value (CF02) and rated
capacity (CF03) are set using the function mode.
The zero point input voltage (CF04), the span input voltage (CF05)
and the display value for the span input voltage (CF06) are set using
calibration mode.
Calibration setting by function mode is also available. (Digital
calibration)
* During calibration, maintain a stable environment or a calibration
error may occur.
* You can confirm stabilization by confirming that the HOLD LED is on.
* The decimal point blinks to indicate that a number is being displayed,
not a weighing value.
7.1. Calibration Modes
With the weighing mode, press and to enter calibration
mode.
Enter zero point calibration mode.
Return to the weighing mode.
7.1.1.
Zero point calibration mode
With nothing on the load cell, wait for
it to stabilize, and then press .
Perform zero point calibration, and
proceed to span calibration mode.
Cancel zero point calibration, and
proceed to span calibration mode.
Hold to display the mV/V of the zero
point.
7.1.2.
Span calibration mode
Add the actual load for span calibration to the load
cell, and then input the value to be displayed when
the load is loaded.
After stabilization, press .
Select the digit to be changed.
Increase the value of the digit to be changed.
Change the polarity.
Perform span calibration, and
proceed to storing mode.
Cancel span calibration, and
proceed to storing mode.
* After the span calibration, the AD-4530 displays the mV/V value of the span
calibration for 3 seconds, and then proceeds to the storing mode.
7.1.3. Storing calibration mode
Store the calibration zero, span and displayed
value acquired.
When calibration was not performed, data is not
stored.
Store the data acquired, and return to
weighing mode.
Do not store the data acquired, and
return to weighing mode.
7.2. Calibration Error
Display Cause
Remedy
C?e2
Voltage at zero point
calibration was too far in the
positive direction.
C?e3
Voltage at zero point
calibration was too far in the
negative direction.
Confirm the rating
and connection of the
load cell.
Display Cause
Remedy
C?e4
The mass value exceeds the
weighing capacity.
Use a proper mass.
C?e5
The mass value is less than
the minimum scale value.
Use a proper mass.
C?e6
The load cell sensitivity is
insufficient.
Confirm the load cell
connection. Use a proper
mass.
C?e7
Voltage at span calibration is
less than the zero point.
Confirm the load cell
connection.
C?e8
When adding a load of the
weighing capacity, the load cell
output voltage is too high.
Use a load cell with a
greater weighing capacity
or set a smaller weighing
capacity value.
8. FUNCTION MODE
Use the function mode to set various functions and data. The set values are
saved in non-volatile memory and are maintained even if the power is
switched off.
8.1. Structure of Functions
The first 2 digits of the Function No. are the function group. The last 2 digits of the
Function No. are the function item.
CF Calibration

F0 Basic
function
F1 Comparator
function
Use this function to set the comparator operation.
F2
Analog output function
Use this function to set the output value of the analog voltage
output and analog current output.
F3, F4 Serial communication function
Use this function to set the RS-232C and RS-485.
* Set the zero point input voltage (CF04), the span input voltage (CF05) and
the display value for the span input voltage (CF06) in calibration mode.
* Set the upper limit value (F101) and lower limit value (F102) in
comparator mode.
When setting a function, the decimal point blinks to indicate that a
number is being displayed, not a weighing value.
8.2.Key operation
In weighing mode, press and to enter the function selection
mode.
8.2.1. Function selection mode
Select the function group. (First 2 digits)
Select the function item. (Last 2 digits)
Enter the setting changing mode.
Save the setting in non-volatile memory, and then return to
weighing mode.
8.2.2. Setting changing mode (Two methods)
Ｐ
Parameter selection method (All digits blinking)
Change the parameter.
Enter the setting and return to function selection mode.
Cancel the setting and return to function selection mode.
Ｄ
Digital input method (Change the blinking digit only)
Move the digit to be changed to the right.
Change the value of the blinking digit.
Change the polarity.
Enter the setting and return to function selection mode.
Cancel the setting and return to function selection mode.
