3. Installation and Precautions

ЗЛ .1. Instailation and Precautions

Aa

AD

The AD-4329 weighing indicator is a precision electronic instrument Handle the Indicator carefully.

The operating temperature is -10t: to *f40t: (14“F to 104"^).

Do not install the scale in direct sunlight.

Misoperation or other problems may be caused by an unstable power source including momentary power failrue or instantaneous noise. Use a stable power source.

Do not connect the power cord before the installation Is finished.

Please confirm that the local voltage and receptacle type are correct for your scale. The jOperate/Standbvi key @ key) can not cut the power. The load cell and the internal circuit are supplied with power in the standby state.

Use shielded cable for ail 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 electric power equipment. There is an earth ground terminal at the power cord receptacle.

□Do not install the scale in a place where it is af3t to be charged with static electricity, or where the relative humidity is lower than 45%RH. Plastic and isolators are apt to be charged with static electricity.

3.1.2.The Load Cell Connections

Connect the load ceil wires to the connector (receptacle), at the rear panel, using the

accessory load cell plug.

□It is possible to connect a 4 wire cable that 1 pin"2pin and 3pin-4pin are shorted, if the distance between the indicator and a load cell is shorter than 5m.

The output voltage of a load ceil is a very sensitive signal. Space the load cell cable away from any noise source.

□It is possible to connect eight 350Q load cells.

The load cel! drive is 5VDC ± 5% between EXC+ and EXC-, the maximum current 120mA.

EXC+	Cable	Positive Sense		Cable
	i\
		Positive Excitation Input	Load Cell Plug
EXC-		Negative Excitation input
		Negative Sense
SIG-		Negative signal Output
S1G+		Positive signai Outpur
Load ceii		Standard		Available connection for
		connection		a cable shorter than 5m.
AD-4329 Weighing Indicator		Page 5		3. Installation and Precaution

3.1.3. Adjustment of the Load Ceil Output

Caution a Use a inetaf film resistor in the range of 50kQ to 500kQ with a good temperature coefficient when adding a resistor to adjust a load cell output. Use as a large resistance value as possible in the range in which 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 S1G+.

3.1.4. Verifying Load Ceil Output and Input Sensitivity

The input sensitivity of the indicator is 0.2pV/division or more. Adapt to the following inequality, when you design a weighing instrument using the indicator and load cell(s).

Caution □ A change in input voltage sensitivity is equivalent to a one division

change of the display. Select as large an Input voltage sensitivity voltage as possible so that the weighing interval becomes stable,

a Consider the leverage If a lever is used.

5. Calibration

This weighing Indicator, converts an input voltage from a load cel! to the "mass*' value, and displays it. Calibration is the adjustment function so that the scale (indicator) can weigh correctly.

5:1,1, items of Calibration Mode_______________________ _____

There are seven items In the calibration function.

Basic Items
The minimum division....................	Setting the weighing interval.
The maximum capacity..................	Setting the maximum display.
Zero calibration... .........................	When unloading any weight on the weighing unit
	( there is nothing on the weighing pan), this function
	performs adjustment so as to display the zero point
	mark. Select an adjustment method from the.
	"weighing input" or "digital input".
Comment This function Is the fundamental starting point to
	weigh anything, and influences the performance of
	scale (indicator).
Span calibration..................... ......	The function to measure an input voltage variation
	by loading to the weighing unit correctly. Select an
	adjustment method from the "weighing arbitrary
	mass", "weighing capacity mass" or "digital input".
Optional Items (Sub-functions)
Range function...... ....................	The function for a multi-interval scale. Select "dual
	range scale" or "triple range scale". Each range has
	parameters of "weighing range" and "division"
pigital linearization function...........	The function to revise a linearity deviation using
	weighing points, (up to three weighing points)

Gravity compensation function... The function to revise weighing error between the calibration location and another weighing location using gravity acceleration.

Caution □ The maximum display is less than or equal to 10000 divisions. This number

is calculated from the maximum capacity divided by the minimum division.

□Check the accuracy of weighing instrument periodically.

□Recommended mass, use a mass heavier than 2/3 maximum capacity.

AD-4329 Weighing Indicator

5. Calibration

□ 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 MD mark is turned off. If unstable data Is used, it may cause a weighing error. Arrange the condition using the FOO filter function.

□The span calibration needs the zero calibration data. We recommend that you perform the span calibration Immediately after the zero calibration.

□Perform the digital linearization function immediately after the zero calibration. And perform the span calibration continuously.

□Select a decimal point and weighing unit at the CF function CFOO, CF 01.

□If you use, the dual or triple range function of the multi-interval scale, perform the “Range Function", “Zero Calibration" and "Span Calibration".
