3. Installation and Precautions
ЗЛ .1. Instailation and Precautions
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.
Aa
Ad
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.

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.

□ 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".
