Reference Sheet, provided for a qui ck reference to the balance operation. Windows Communication T ools (WinCT), allo ws easy communication with a Windows-based personal computer .
6 2. UNPACKING THE BALANCE 2-1 Unpacking The balance is a precision in strument. Unpack the balance care fully . Keep the packing material to be used for transporting the balance in the future. See the illustrations to confir m that everything is contained.
7 Notes About how to attach the mounting fi xtures, refer to “26. ATTACHING THE MOUNTING FIXTURES” on page 91. Please confirm that the AC adapter type is correct for your local voltage and receptacle type. Calibration weight OIML, Class E2 or equivalent Mounting fi xtu re (2 pcs.
8 2-2 Installing the Balance Caution The weighing unit and the display unit were ad justed as a unit. Therefore, make sure that the weighing unit and the display unit have the same serial number . The serial number is printed on the rear of the weighing unit and the display unit.
9 How to disconnect the cable from the w eighing unit Slide the connector sleeve in t he direction of the arrow to unlock and gently pull the connector out. 4. Adjust the leveling feet to level the weighi ng unit. Confirm it using the bubble spirit level.
10 3. PRECAUTIONS T o get the optimum performance from the balan ce and acquire accurate weighing data, note the following: 3-1 Before Use Install the balance 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 .
11 3-2 When Building into a System The AD-4212A/B is a precision bal ance. When it is built into a sy stem and used, errors such as unstable weight values may occur due to static electricity , vibr ation and materials used for the devices near the balance.
12 When an o perator is static charged If an operator ’s clothes are static charged, especially in winter , it may be a cause for unstable weight values. Wear an anti-st atic wrist strap. Errors due to air flow Where the i nfluence of am bient air flow is great such as: close to an air conditioner , door or passage way .
13 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 alum inum or brass between the sample and the balance, also keep an appropriate dist ance between them while weighing.
14 4. DISPLAY SYMBOLS AND KEY OPERATION Key operation Key operation affects how the balance func tions. The basic ke y operations are: “Press and release the key immediately” or “Press the k.

18 6. WEIGHING 6-1 Basic Operation (Gram Mode) 1 Plug in the AC adapter. 2 Press the ON:OFF key to display the weighing mode. (The decimal point position depends on the balance model.) Notes The auto display-ON function is available to display the weighing mode without the key operation when the AC adapter is plugged in.
19 6-2 Smart Range Function The AD-4212B-101 is equipped with two ran ges. T he precision range ha s a higher resolution. The standard range has normal resolution. The range switches automatically , depending on the value displayed. Pressing the RE-ZERO key allows weighing in the precision range, regardless of the tare value.
20 7. CHANGING THE WEIGHING SPEED The weighing speed can be selected from the follo wing three rates to minimize the influence on weighing that is caused by draft s and/or vibrati on at the place where the balance is inst alled. Indicator Parameter Speed Stability FAST Cond 0 MID.
21 8. CALIBRATION Calibration Calibration using the calibration weight Calibration test T o check the weighing accuracy , using the ca libration weight, a nd output the result. (Calibration test does not perform calibration.) Caution Calibration adjusts the balance for accurate weighing.
22 8-1 Calibration This function calibrates the balance using the calib ration weight. (Display example: AD-4212B-102) Operation 1 Plug in the AC adapter and warm up the balance with nothing on the pan. • AD-4212A series balance: 30 minutes or more • AD-4212B series balance: one hour or more For the mod els with a minimum displa y of 0.
23 5 Confirm that there is nothing on the pan and press the PRINT key. The balanc e measures the zero point. Do not allow vibration or drafts to affect the balance. The balance displays the calibration weight value. 6 Place a calibration weight, of the weight val ue displayed, on the pan and press the PRINT key.
24 8-2 Calibration Test This function tests the balance weighing accuracy using the calibration weight and outputs the result. This is available only when the “GLP output ( info )” parameter is set to “ 1 ” or “ 2 ”. (Calibration test does not perform calibration.
25 5 Confirm that there is no thing on the pan and press the PRINT key. The bala nce measures the zero point and displays the measured value. Do not allow vibration or drafts to affect the balance. The balance displays the calibration weight value. 6 Place a calibration weight, of the weight value displayed, on the pan and press the PRINT key.
26 9. FUNCTION SWITCH AND INITIALIZATION 9-1 Permit or Inhibit The balance stores parameters that must not be changed unintentionally (e.g. Calibration data for accurate weighing, data for adapting to the operat ing environment, control data for the RS-232C interface).

34 Zero tracking ( trc ) This function tracks zero point drift caused by changes in the environment and st abilizes the zero point. Three levels of zero tracking are available. When the weight value is onl y a few digit s, turn the function off for accurate weighing.
35 T are at st art ( p-tr ) When a hopper is attached to the weighing pan and loss-in weighing is performed, t he remaining amount of the material will become unknown if tare is performed each time a weighing st arts. When " p-tr 0 " is selected, tare is not performed at we ighing start.

H H (to conf irm secondary upper limit value) Response H H , + 100.00000 g ( s e c ondary upper limit value=100.000 00 g) Command ?HI (to confirm upper limit value) Response H I + 080.
46 11. ID NUMBER AND GLP REPORT The ID number is used to ident ify the balance when Good Laboratory Practice (GLP) is used. The ID number is maintained in non-volatile memory even if the AC adapter is removed.
47 11-2 GLP Report Set the following parameters to output the report. T o print the report, set the “GLP output ( info )” parameter to “ 1 ” and use MODE 3 of the AD-8121B. For details on using the printer , refer to “17-1 C onnection to the AD-8121B Printer”.
48 Calibration test report using an external weight (Calibration test does not perform calibration.) When the setting is “ info 1 ”: When the setting is “ info 2 ”: AD-812 1 format Gener al da.
49 Title block and end block When weight values are recorded as GLP data, a “T itle block” is inserted at the beginning and an “End block” is inserted at the end of a gr oup of weight values in the GLP report. Notes To output the report to an AD-8121B , use MODE 3 of the AD-8121B.
50 12. COUNTING MODE (PC) This is the mode to determine t he number of obje cts in a sample based on the standard sample unit mass. The unit mass is the mass of one piece of the sample. The smaller the variables in each sample unit mass are, the more accurate the co unting will be.
51 Notes If the balance judges that th e mass of the samples is too light and is not adequate to be used as the unit mass, i t display s 1 lo . In that case, store th e mass by some quan tit y . For example, w hen the model wi th the minimum w eighing value of 0.
52 13. PERCENT MODE (Pct) This is the mode to display the weight value in percentage comp ared to a 100% reference mass and is used for target weighing or checking the sample variable. Selecting the percent mode 1 Set “ Unit selection ( Unit ) ” parameter of the function table to pct (percent mode).
53 14. DATA MEMORY Data memory is a function to store weighing data or calibration data to display or output later .
