2. UNPACKING THE BALANCE 2.1. Unpacking The balance is a precision instrument. Unpack the balance carefully. Keep the packing material to be used for transporting the balance in the future. When unpacking, see the illustration below to confirm that everything is contained. AC adapter jack Weighing pan Screws (Flat head: M4 X 6) Pan support RS-232C connector AC adapter plug Grounding terminal (See note below.
ATTACHING THE AD-4212C SERIES WEIGHING UNIT DIRECTLY ON THE MOUNTING BASE When the AD-4212C series weighing unit is built into a system, remove the three leveling feet and use the screw holes to secure the weighing unit to the base. Attachment Procedure 1. Remove the three leveling feet. Caution Do not remove any other screws from the bottom of the weighing unit. Doing so could damage the weighing sensor. Weighing unit 2. Secure the weighing unit from above.
2.2. Installing the Balance Install the balance as follows: 1. Refer to “3. PRECAUTIONS” for installing the balance. 2. Refer to "2-1 Unpacking" on page 6, to attach the pan support and the weighing pan on the weighing unit. 3. Insert the RS-232C cable into the jack located on the rear of the weighing unit. Rear of the weighing unit When confirming the performance of the weighing unit using WinCT-AD4212C, connect the cable into RS-232C terminal of the computer.

3. PRECAUTIONS 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.
3.2. When Building Into a System The AD-4212C is a precision balance. When it is built into a system, errors such as unstable weight values may occur due to static electricity, vibration, sample temperature and magnetism of the materials weighed or used for the devices near the balance.
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.
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, 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. Where the influence of heat or drafts is great Eliminate temperature differences Draft between a sample and the environment.
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.
4. OPERATION OF WinCT-AD4212C The software has the following functions: - Set the weighing speed - Set the minimum display value - Calibration - Set the baud rate • The parameters set using these functions, are stored in non-volatile memory, and maintained, even if the AC adapter is removed,. - A data logging function, allows confirmation of the weighing data after weighing Before use 1. Install the WinCT-AD4212C into the computer. For details, refer to Readme of WinCT-AD4212C. 2.
4.1. Changing the Weighing Speed Using WinCT-AD4212C The weighing speed can be selected from the following three rates to minimize the influence on weighing that is caused by drafts and/or vibration at the place where the balance is installed. Indicator FAST MID. SLOW Speed Fast Slow Weighing speed setting Stability Sensitive value Stable value Operation MODE 1. Press the MODE button. 2. Press the MODE button to select a weighing speed. Either FAST, MID. or SLOW can be selected.
Calibration procedure This function calibrates the balance using the calibration weight. (Display example: AD-4212C-300) Operation 1. Plug in the AC adapter and warm up the balance for 30 minutes or more with nothing on the pan. 2. Press the CAL button. Cal 0 is displayed. Press CAL If you want to cancel calibration, press the CAL button. The balance will return to the weighing mode. If you want to change the calibration mass value, press the SAMPLE button.
4.3. Changing the Baud Rate Using WinCT-AD4212C Operation 1. Click the [Settings] tab. 2. Select the baud rate to be used and click the Set [Settings] tab Set button 3. “Completed” appears when the setting is complete. 18 button.
5. SMART RANGE FUNCTION The AD-4212C-301/3100 are equipped with two ranges. The precision range has a higher resolution. The standard range has a normal resolution. The range switches automatically, depending on the value displayed. Sending the R command allows weighing in the precision range, regardless of the tare value. The range can be fixed to the standard range by changing the minimum weighing value using the SMP command.
6. COMMUNICATION SPECIFICATIONS The AD-4212C series can communicate interactively using RS-232C. The AD-4212C series can continuously transmit the weighing data. (Approx.10 times/second* to 50 times/second) The AD-4212C series is DCE. The AD-4212C series can connect directly to the RS-232C terminal of a personal computer by using the accessory RS-232C cable. * Factory setting 1.

4. Command The balance can be controlled by the following commands. When transmitting, add the terminator to each command. Commands to query weighing data When the display is turned on, the AD-4212C series outputs the weighing data continuously. To use the Q or S command, send the C command to stop the continuous data output, then request the weighing data using the Q or S command. Command C Q S SIR Description Cancels the SIR command. Requests the weighing data immediately.

7. MAINTENANCE Do not disassemble the balance. Contact the local A&D dealer if the balance needs service or repair. Use the original packing material for transportation. Do not use organic solvents to clean the balance. Clean the balance with a lint free cloth that is moistened with warm water and a mild detergent.
8. TROUBLESHOOTING 8.1. Checking the Balance Performance and Environment The balance is a precision instrument. When the operating environment or the operating method is inadequate, performing accurate weighing will not be possible. If the balance seems to have a problem with repeatability or to perform improperly, check as described below. Also, visit our website, http://www.aadd.co.jp/, for “Information Library” and “FAQ”. If improper performance persists, contact the local A&D dealer for repair.
Sample and container Has the sample absorbed or lost moisture? Has the temperature of the sample, and the container if used, been allowed to equalize to the ambient temperature? Refer to “3-2 When Building into a System”. Is the sample charged with static electricity? Refer to “3-2 When Building into a System”. Is the sample of magnetic material such as iron? Use much care when weighing magnetic materials. Refer to “3-2 When Building into a System”. 8.2.
