2. Outline and Features The AD-4430B has the following features. The weighing module is a weighing indicator that amplifies signals from a load cell, converts it to digital data and displays it as a mass value. This indicator has the following performance : Input sensitivity : ............................ 0.15 μV / d (d = minimum division) Display resolution : ........................ 99,999 d in maximum Sampling rate : ............................... 1000 times/second Input voltage range : ..............

4. Installing The Module This section is explained for the environment to install the module and for the terminals of the power source and load cell cable. Refer to each section of options for I/O interface. 4.1. Conditions To Install The Module The module is a precision electronic instrument. Handle it carefully. The operating temperature is -10°C to +50°C. Do not install the module in direct sunlight. 4.2. Power Supply Earth ground the module to prevent electrical shock or indicator malfunction.
4.4. Shield Cable Connect the load cell shield wire only to the shield terminal of the AD-4430B. As a general rule, No ground is connected between the load cell and the AD-4430B. This is to prevent the ground loop generated by multiple ground points. A ground loop can be created along the wiring route, and interference such as high-frequency noise becomes more likely. 4.5.
Type Advantages Disadvantages The error is small even when the load cell cable 6-wire is extended, a thin load connection Complicated wiring cell cable is used, or (recommended) multiple load cells are used. The influence of the load cell cable resistance worsens the 4-wire temperature coefficient. Simple wiring connection Prone to the influence of the contact resistance of the connector Description Use a 6-wire shielded cable when a summing box is used.
5. 5.1. 5.1.1. Operations General Functions Zero Adjustment Zero adjustment is a function to set the gross weight to zero. It is performed by pressing the (ZERO) key. The zero adjustment range is set in CAL05 ( Zero adjustment range ) and is expressed in percent of the weighing capacity with the calibration zero point as the center. Zero adjustment is disabled, even within the zero adjustment range, when the A/D converter overflow occurs. A ZERO error is output if zero adjustment is not performed.
Clearing The Tare Weight And Zero Adjustment The way to clear the tare weight and zero adjustment : While pressing and holding the (TARE) key, turn on the module. Another way : In turning off the module, while pressing and holding the (TARE) key, press the key. 5.1.4. Customizing The Function Of the Switch F Assign a function to the key in the general functions.
5.1.5. Customizing The Function Of the Display x Assign a function to the display x in the general functions.
5.1.9. The Hold Function There are three types of hold functions which can be used for different purposes. Normal hold Holds the value displayed at the time the hold command was received. Peak hold Holds the maximum value reached after the hold command was received. The value will be refreshed if it increases again. Averaging hold This function averages weighing data over a certain period of time and then holds the result.
5.2. Mode Map And Operation Switches 5.2.1. Mode Map The module has several modes to perform various operations. Perform mode switching by the key operation shown below, only in the direction of the solid arrow. After setting a mode, the module resets automatically. Alternatively, the module resets when the power is disconnected.
5.2.2. Key Operation Switches State Function and Use Weighing mode The display switch between gross and net in factory setting. Weighing mode The zero key to perform the zero adjustment. Setting mode The key to change a selected item or move a flashed figure. Weighing mode The tare key. Setting mode The key to select parameter or increase number. Weighing mode When turning off the module, press and hold the key. OFF mode (Standby) When turning on the module, press the key.
5.3. 5.3.1. Calibration Outline In the calibration mode, the operation to relate the output voltage from a load cell to the mass value and other operations directly related to weighing are performed. Calibration is performed using a calibration weight. Zero calibration : ..................Press key when no load is applied. Calibration with an actual load Span calibration : .................Enter the calibration weight value and place the calibration weight.
5.3.2. The Calibration With An Actual Load (Using A Mass) Calibration is performed using a calibration weight. Before performing calibration for the first time, set the unit, decimal point position, minimum division and weighing capacity in the calibration-related function mode ( C-Fnc ). Note To avoid drift caused by changes in temperature, warm up the indicator for ten minutes or more before performing calibration with an actual load.
5.3.3. Gravity Acceleration Correction When the scale (module) has been calibrated in the same place as it is being used, gravity acceleration correction is not required. A span error will appear if there is a gravity acceleration difference between the place where the module has been calibrated and the place where it is being used.
Illustration 8 Gravity Acceleration Graph 5.3.4. Outline Of The Linearization Function Even if zero and span points have been calibrated, weighing errors may occur between the zero point and weighing capacity. This is a corrective function designed to non-linearly correct weighing errors. It is possible to input up to four points in addition to the zero point. The zero point and each input point will be corrected to put them in a straight line.
