2. Introduction Page 4 AD-4405 Weighing Indicator

3. Installation and Precautions

3.1.1.Installation and Precautions

The AD-4405 weighing indicator is a precision electronic instrument. Handle the indicator carefully.

The operating temperature is -10°C to +40°C (14°F to 104°F).

Do not install the scale in direct sunlight.

Mis-operation or other problems may be caused by an unstable power source including momentary power failure or instantaneous noise. Use a stable power source.

Do not connect the power cord before the installation has been completed. Verify that the local voltage and receptacle type are correct for your scale.

Use shielded cable for all connections. Connect the cable shields to the shield terminal or case as an earth terminal.

Earth ground the indicator. Do not join the earth ground line with other electrical power equipment. There is an earth ground terminal at the power cord receptacle. Do not install the indicator in a place where it is apt to be charged with static electricity, or where the relative humidity is lower than 45%RH. Plastic and insulating materials are apt to be charged with static electricity.

3.1.2.The Load Cell Connections

Connect the load cell wires to the connector (receptacle), at the rear panel, using the accessory load cell plug.

It is possible to connect a 4 wire cable provided that pins 1-2 and pins 3-4 are shorted, if the distance between the indicator and the load cell is shorter than 5m. The output voltage of a load cell is a very sensitive signal. Space the load cell cable away from any noise source.

It is possible to connect four 350ohm load cells.

The load cell drive is 5VDC 5% between EXC+ and EXC-, the maximum current 60mA.

AD-4405 Weighing Indicator

Page 5

3. Installation and Precautions

A change in input voltage sensitivity is required to cause a one division change of the display. Select as large an input sensitivity voltage as possible so that the weighing interval becomes stable.

Consider the leverage if a lever is used.

3.1.3.Adjustment of the Load Cell Output

Caution Use a metal film resistor in the range of 50kohm to 500kohm with a good temperature coefficient, when adding a resistor to adjust a load cell output. Use as large of a resistance value as possible in the range in which the zero adjustment is possible. Solder this resistor at a point near the load cell or the indicator.

In Case of Reducing the Output Voltage

When the zero output is too large, add a resistor between EXC+ and SIG-.

In Case of Adding an Offset Voltage to the Output

When the zero output is too small, add a resistor between EXC+ and SIG+.

3.1.4.Verifying Load Cell Output and Input Sensitivity

The input sensitivity of the indicator is 0.25mV /division or more. Adapt to the following inequality, when you design a weighing instrument using the indicator and load cell(s).

Caution

						E * B * D
	Weighing instrument				0.25 £

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.

5.1.1.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.

AD-4405 Weighing Indicator

Page 11

5. Calibration

Note that the ON/OFF key does not function alone. Press the ESC key while holding the ON/OFF key to end the calibration mode, if mis-operation. After displaying Can5el, press the ON/OFF key to end the calibration mode and turn the indicator off.

NOTE: When displaying Caloff , press the +/- key while pressing the ON/OFF key, instead of CAL key. However, in some cases, settings are altered to nullify this option.

Caution		The maximum display is less than or equal to 40000 divisions. This number
		is calculated from the maximum capacity divided by the minimum division.
		Check the accuracy of the weighing instrument periodically.
		Recommended mass, use a mass heavier than 2/3 maximum capacity.
		Calibrate the scale, if it is moved to another location or the environment
		has changed.
		It is not necessary to set the gravity acceleration correction, when calibrating
		the scale with a calibration mass at the place where the scale is used.
		Enter the stable weighing data while the STABLE mark is displayed. If
		unstable data is used, it may cause a weighing error. Arrange the
		condition using the F00 filter function.
		The span calibration needs the zero calibration data. We recommend
		that you perform the span calibration immediately after the zero
		calibration.
		If you use the dual range function of the multi-interval scale, perform the
		"Range Function", "Zero Calibration" and "Span Calibration".

5.2. Calibration Procedure

5.3. Weighing Range Function

5.3.1.Setting the Division and Range

Consider the following rules to design the weighing range.

Rule 1 Select the division and range of each weighing range so as to fit the following inequality. The first range < the second range

The division of the next weighing range is automatically set larger than the division of the lower weighing range. And the division can change.

Rule 2 When setting the dual range, the upper limit value of the second range becomes the maximum capacity.

Rule 3 Select a resolution smaller than 40000. The resolution is a value that divides the maximum capacity by the minimum division of the first range.

5.4. Digital Linearization Function

Even if the zero and span calibration have been completed, there may still remain a linearity deviation caused by the performance of the weighing unit. The digital linearization function can rectify or reduce the linearity deviation using weighing points during the zero and capacity setting. Up to three weighing points can be specified.

Caution		This function does not improve repeatability or hysteresis.
		Use the mass on the condition that lnr 1 < lnr 2 < lnr 3.

Do not press the ENTER key while the STABLE mark is off.

Step 1	Check the	Cal 0	display. Press the	MODE	key to display	lnr 0	.
Step 2	Enter the zero point. Refer to “5.2.3. Zero Calibration”.

Step 3			The value of the middle point is displayed after indicating				lnr x. x is 1, 2 or 3.
			The triangle
					mark of the same number(x) is displayed along with the value.
Step 4 Select a middle point.
			If you want to cancel the current procedure, press the			ESC		key to finish this
			function. Proceed to step 7 and other points are cleared (canceled).
			Select a middle point value using the 0 - 9 keys. Proceed to step 5.
Step 5			Place a mass equivalent to the displayed value on the weighing unit. Press the
			ENTER	key after the STABLE mark has turned on. Proceed to step 6.
Step 6			If you include a 2nd and 3rd middle point, repeat steps 3, 4, 5 for each.
			If you finish this function, proceed to step 7.
Step 7			Perform step 11 of "5.2.4. Span Calibration" immediately.

5.5. Gravity Compensation Function

If the scale is used at the calibration location, it is not necessary to perform this function. If there is a difference of gravity acceleration between the installed location and calibration location it may cause a weighing error. This function specifies the gravity accelerations and corrects the span error.

Note		The decimal point is not displayed in the function. Example:	9798	= 9.798 m/s2
		When span calibration is executed, the gravity acceleration correction will
		be cleared and the two gravity acceleration values will return to the factory
		settings.

Step 1 At the Cal 0 display, press the MODE key twice, g 5et is displayed and press the

ENTER key to enter the gravity compensation function.

If you want to cancel the current procedure, press and hold the ON/OFF key and press the ESC key. Then, no parameters are changed and the calibration mode is finished. Press the ON/OFF key to turn the display off after displaying CanCel.

Step 2 The parameter is displayed with triangle 1. Enter the gravity acceleration of the calibration location using the 0 - 9 keys. The parameter xxxx is the gravity acceleration.

ENTER key...The key to store the new gravity acceleration and proceed to step 3.

ESC key .......The key to return to g 5et without changing the value.

Step 3 The parameter is displayed with triangle 2. Enter the gravity acceleration of the installed location using the 0 - 9 keys. The parameter xxxx is the gravity acceleration.

ENTER key...The key to store the new gravity acceleration and proceed to step 4.

ESC key .......The key to return to step 2 without changing the value.

Step 4 Now g xxxx is displayed. Press the CAL key to store the parameters. Caloff is displayed. Proceed to step5.

Caloff could be displayed by pressing the +/- key while pressing the ON/OFF key instead of the CAL key.

Step 5 Press the ON/OFF key to turn the display off.
