Notes

If the balance is to be used in a range other than shown above, contact the local A&D dealer.

To avoid the effects of static electricity or magnetism, use materials other than resin or magnetic materials when designing a weighing pan.

When a locally fabricated weighing pan is used, the zero point may be shifted greatly right after the AC adapter is plugged in. Perform re-zero before weighing to cancel the amount of zero drift as necessary.

10

To get the optimum performance from the balance and acquire accurate weighing data, note the following:

3.1. Before Use

 Install the weighing unit in an environment where the temperature and humidity are not excessive. The best operating temperature is about 20°C / 68°F at about 50% relative humidity.

 Install the weighing unit where it is not exposed to direct sunlight and it is not affected by heaters or air conditioners.

 Install the weighing unit where it is free of dust.

 Install the weighing unit away from equipment which produces magnetic fields.

 Install the weighing unit in a stable place avoiding vibration and shock. Corners of rooms on the first floor are best, as they are less prone to vibration.

 Ensure a stable power source when using the AC adapter.

 Connect the power to the balance using the AC adapter at least one hour before use, but in the case of the AD-4212D-33/32, four hours are required. It is recommended to connecting the power to the balance.

 Calibrate the balance before use or after having moved it to another location.

In addition, calibrate it periodically to maintain the accuracy.

Caution

Do not install the balance where flammable or corrosive gas is present.

11

3.2. When Building Into a System



Errors due to a static charge and measures to take

When the ambient humidity is less than 45% RH, insulators such as plastic or glass are prone to static electricity. When charged material comes close to the balance, a pulling force is generated by static induction between the charged material and the weighing pan. This causes an unstable weight value.

To protect the balance against a discharge generated by charged material when it comes close to the balance, be sure to earth ground the weighing unit and the display unit.

Note that static electricity generated by static induction will not be canceled by earth-grounding.

Use a humidifier or the AD-1683 DC static eliminator,

Charged plastic breeze break

The pulling force causes an unstable weight value

Charged sample

Weighing unit

A pulling force generated between the charged sample and the balance causes an unstable weight value.

Measures to take (Plastic is used in the examples below. They can be applied to glass, too.)

When the sample or devices are plastic

 Use a static eliminator that generates no air blow such as the

AD-1683, DC static eliminator, to remove static electricity.

 Place the sample in a container that is made of a conductive material such as metal and that can be sealed, and then weigh it.

Charged material

Metal case

When the sample is powdery

 When the balance is used in combination with a feeder for batch weighing of powdery samples, samples may be charged by rubbing sample particles against each other.

Use a static eliminator and perform weighing while removing static electricity.

Grounding

When the sample container is made of material that is prone to static electricity such as plastic

 Cover the outside of the container with a metal such as aluminum foil.



Apply an anti-static agent onto the container.

When making a breeze break using plastic

 Apply an anti-static agent onto the breeze break.



Use a conductive acrylic fiber.

When plastic exists in the balance installation site

 Cover the plastic with a grounded conductive material.

 Apply an anti-static agent onto the plastic.

When an operator is static charged

If an operator’s clothes are static charged, especially in winter, it may be a cause for unstable weight values.

12

 Wear an anti-static wrist strap.



Errors due to air flow and measures to take

Where the influence of ambient air flow is great such as: close to an air conditioner or fan, door or passage way. Even very subtle air flow that is hard to be detected may influence the weighing operation.

 Avoid those areas as a weighing site.

 If weighing is to be performed in such an area, use a breeze break or take other appropriate measures.

Influence of the air flow makes the weight value unstable

Where the influence of heat or drafts is great

 Eliminate temperature differences between a sample and the environment.

When a sample is warmer (cooler) than the ambient temperature, the sample will be lighter (heavier) than the true weight.

This error is due to a rising (falling) draft around the sample.

 Do not touch the sample directly with your hand. Use tweezers or other tools.

If you touch the sample, the same type

Draft

20 C

40 C error described above will occur.

 Do not perform weighing where it is exposed to direct sunlight. Weighing errors may occur due to sudden temperature change or drafts.



Errors due to vibration and measures to take

Where the influence of vibration is great, such as:

(1) Soft ground (2) Second or higher floor (3) Near center of a floor far from pillars (4) Seismic isolated structures (5) Near tall buildings.

In the areas listed above, the scale may yield unstable weight values on windy days or after an earthquake. Especially in case of (4) and (5), weight values may be unstable for a long period of time because of long lasting low-frequency vibration after strong winds or an earthquake.



Errors due to other causes and measures to take

Change in temperature or humidity

A sudden change in temperature or humidity can generate a draft and cause the balance to absorb or exude moisture, which leads to unstable displays.

 Avoid sudden change in temperature or humidity.

 Use an air conditioner or humidifier to control the temperature or humidity.

Magnetic material

The balance uses a strong magnet as part of the balance assembly, so use much care when weighing magnetic materials.

 Place a non-magnetic object such as aluminum or brass between the sample and the balance to keep an appropriate distance between them while weighing.

13

3.3. During Use

 To minimize the affect by electrical noises, earth ground the weighing unit and the display unit (option).

 Do not drop things upon the weighing pan, or place a sample on the pan that is beyond the balance weighing capacity. Place a sample in the center of the weighing pan to minimize corner-load errors.

 To prevent possible errors, before each weighing, perform re-zero using the RS-232C command, or calculate the difference between the weight value before and after weighing.

 Take into consideration the affect of air buoyancy on a sample when measuring the absolute value with the minimum weighing value of 0.1 mg.

 While cleaning, attaching the waterproof cap to the unit instead of the weighing pan results in the AD-4212D becoming dust-proof and drip-proof and conforming to IP65. Be sure to clean the weighing pan and keep the conditions around the pan clean after weighing powdery, fluid samples or metallic strips.

 Balance status is indicated by the pilot lamp.

3.4. After Use

 Avoid mechanical shock to the weighing unit.



Periodically calibrate the balance using the internal weight or a calibration weight.

 Do not disassemble the weighing unit. Contact the local A&D dealer if the balance needs service or repair.

 Do not use organic solvents to clean the weighing unit. Clean the weighing unit with a lint free cloth that is moistened with warm water and a mild detergent.

 Avoid dust and water so that the weighing unit weighs correctly. Protect the internal parts from liquid spills and excessive dust.

3.5. Power Supply

 When the AC adapter is connected, the balance is in the standby mode if the standby indicator is on (refer to “4. BASIC OPERATON (WHEN USING THE AD-1691)”). This is a normal state and does not harm the balance. For accurate weighing, plug in the AC adapter and warm up the balance for the appropriate duration before use.

 The factory setting is the precision range.

* When the weight value exceeds 5.1 g while the minimum weighing value of 0.000001 g

(precision range) is used, the balance will switch to the minimum weighing value of

0.00001 g (standard range). By touching the RE-ZERO button or sending the R command, the balance can weigh from that point up to 5.1 g, using the minimum weighing value of

0.000001 g (precision range).

6. UNDERHOOK

The underhook can be used for magnetic materials or density measurement. The built-in underhook is revealed by removing the cap on the bottom of the balance. Use the underhook as shown below.

Caution

Do not apply excessive force to the underhook.

When not in use, attach the cap to prevent dust from getting into the balance.

Do not push the underhook upward

When turning the balance over, parts and weighing matter in the weighing chamber will fall off. (Parts: the weighing pan and fine range ring)

Remove them first.

Condition ( Cond )

Cond 0

This parameter is for sensitive response to the fluctuation of a mass value. Used for powder target mass, weighing a very light sample or when quick response weighing is required.

Cond 2 This parameter is for stable weighing with slow response. Used to prevent a mass value from drifting due to vibration or drafts.

Notes In automatic response adjustment, this parameter is selected automatically.

Stability band width ( 5t-b )

This item controls the width to regard a mass value as a stable value. When the fluctuation per second is less than the parameter, the balance displays the stabilization indicator and outputs.

The parameter influences the "Auto print mode". Currently displayed minimum display means 1 digit.

Example) If the RANGE button was touched to select the 1 mg display at the AD4212D-301, 1 mg means 1 digit.

5t-b 0 This parameter is used for sensitive response of the stabilization indicator. Used for exact weighing.

5t-b 2 This parameter ignores slight fluctuations of a mass value. Used to prevent a mass value from drifting due to vibration or drafts.

Zero tracking ( trc )

This function tracks zero point drift caused by changes in the environment and stabilizes the zero point. When the weighing data is only a few digits, turn the function off for accurate weighing. trc 0 The tracking function is not used. Used for weighing a very light sample. trc 1 The normal tracking function is used. trc 2 The strong tracking function is used. trc 3 The very strong tracking function is used. Used for stable zero display.

Display refresh rate ( 5pd )

The periodic time to refresh the display. This parameter influences "Baud rate", "Data output pause" and the data output rate of "Stream mode".

Decimal point ( pnt )

The decimal point format can be selected.

Connection to a computer using the RS-232C Interface

Features

The balance is of the DCE type (Data Communication Equipment), which can be connected to a personal computer using the RS-232C interface. Before connection, read the personal computer manual thoroughly.

Using Windows Communication Tools Software (WinCT)

When Windows is used as an operating system in a personal computer, the WinCT software can be used to transmit the weighing data to the personal computer.

The WinCT software has three communication methods: "RsCom", "RsKey" and "Rsweight ".

Refer to the WinCT instruction manual.

The current version of the WinCT can be downloaded from the A&D website.

RsCom

RsCom can transmit commands to control the balance.

RsCom can make bi-directional communication between the balance and a personal computer using the RS-232C interface.

RsCom can display or store the data using a text file format. RsCom can also print the data using a printer connected to the personal computer.

When several ports of a personal computer have balances connected, the personal computer can communicate with each balance simultaneously.

RsCom can share a personal computer with other application software.

RsKey

RsKey can transmit the weighing data output from the balance directly to other application software such as Microsoft Excel.

RsKey can be used with most application software.

RsWeight

Can retrieve the weight data from the balance and display the data as a graph in real time.

Can calculate and display the maximum, minimum, average, standard deviation and coefficient of variation.

Using the WinCT software, the balance can do the following :

Analyzing the weighing data and the statistics input by "RsKey"

The weighing data can be input directly into an Excel worksheet. Then, Excel can analyze the data to obtain total, average, standard deviation, maximum and minimum value, and display them in a graph.

Controlling the balance using commands from a personal computer

By using "RsCom", the personal computer sends commands such as "re-zero" or "send weighing data" to the balance and controls the balance.

Receiving weighing data at a certain interval

The weighing data can be received at a certain interval and data characteristic with elapsed time can be obtained.

Using a personal computer as an external indicator

With the "RsKey" test mode function, a personal computer can be used as an external display for the balance. (To do this, set the balance data output mode to stream mode.)

Acknowledge Code And Error Codes

When the "Serial interface function (5if)" parameter is set to "erCd on", the balance outputs

<AK> code or error code to each command as follows:

<AK> (06h) Acknowledge in ASCII code.

When the balance receives a command to request data and can not process it, the balance transmits an error code (EC, Exx).

When the balance receives a command to request data and can process it, the balance outputs the data.

When the balance receives a command to control the balance and can not process it, the balance transmits an error code (EC, Exx).

When the balance receives a command to control the balance and can process it, the balance transmits the acknowledge code.

9.3. Checking The Balance Performance And Environment

The balance is a precision instrument. When the operating environment or the operating method is inadequate, correct weighing can not be performed. Place a sample on the pan and remove it, and repeat this several times. If the balance seems to have a problem with repeatability or to perform improperly, check as described below. If improper performance persists after checking, contact the local A&D dealer for repair.

Checking that the operating environment or weighing method is proper

Operating environment

Is the weighing table solid enough?

Is the balance level?

Is the operating environment free from vibration and drafts?

Is there a strong electrical or magnetic noise source such as a motor near the balance?

Weighing method

Does the weighing pan rim touch anything? Is the weighing pan installed correctly?

Is the RE-ZERO button touched before placing a sample on the weighing pan?

Is the sample placed in the center of the weighing pan?

Has the balance been calibrated using the internal weight (one-touch calibration)?

Has the balance been warmed up for one hour before weighing? (At the AD-4212D-33/32, duration of four hours or more are required.)

Sample and container

Has the sample absorbed or lost moisture due to the ambient conditions such as temperature and humidity?

Has the temperature of the container been allowed to equalize to the ambient temperature?

Is the sample charged with static electricity?

Is the sample of magnetic material such as iron? There are cautions about weighing magnetic materials.

Checking that the balance performs properly

Check the balance performance using an external weight. Be sure to place the weight in the center of the weighing pan.

Check the balance repeatability, linearity and calibrated value using external weights with a known value.

Check whether the calibration is performed correctly. If an error occurs and the calibration can not be performed quickly, the balance may not measure correctly.

9.4. Asking For Repair

If the balance needs service or repair, contact your local A&D dealer.

The balance is a precision instrument. Use much care when handling the balance and observe the following when transporting the balance.

Use the original packing material for transportation.

Remove the weighing pan, pan support, rings and dust plate from the main unit.

Stable value

Environment

Calibration

Output

Zero point

The weight value when the stabilization indicator appears.

Ambient conditions such as vibration, drafts, temperature, static electricity or magnetic fields which affect the weighing operation.

Adjustment of the balance using the calibration weight so that it can weigh accurately.

To output the weighing data using the RS-232C interface.

A weighing reference point or the zero display. Usually refers to the value displayed when nothing is on the weighing pan.

Digit

Tare

Re-zero

Unit of minimum display. Used for the balance, the minimum displayable weighing value.

To cancel the weight of a container which is not included in the weighing data.

To set the display to zero.

GLP Good Laboratory Practice.

Repeatability Variation in measured values obtained when the same weight is placed and removed repetitively. Usually expressed as a standard deviation. e.g. Standard deviation=1 digit: This means that the measured values fall within

1 digit at a probability of about 68%.

Stabilization time Time required after a sample being placed, until the stabilization indicator illuminates and the weighing data is displayed.

Sensitivity drift An affect that a change in temperature causes to the weighing data. Expressed as temperature coefficient. e.g. Temperature coefficient = 2 ppm/

C : If a load is 100 g and the temperature changes by 10

C, the value displayed changes by the following value.

0.0002%/

C x 10C x 100 g = 2 mg
