Page 5: Introduction
The EK-AEP series are intrinsically safe electronic balances complying with international standards such as IECEx and ATEX or FM requirements. The EK-AEP series balances can be used in areas where explosive atmospheres are present. (For details on the intrinsically safe structure, refer to “5. -
Page 6: Safety Instructions And Precautions
3. SAFETY INSTRUCTIONS AND PRECAUTIONS 3-1. Safety Instructions on Intrinsically Safe Structure Do not disassemble or modify the balance. When determining the installation site, take the following into consideration. Will explosive gases be generated? How often will they be generated? Refer to “5. -
Page 7: Precautions On Power Source
As a power source, only the four “AA”, “LR6” or “AM3” alkaline 1.5 V batteries listed below can be used. DURACELL MN1500, ENERGIZER E91, Panasonic LR6(XJ) The intrinsically safe performance of the EK-AEP series balance is guaranteed by using the batteries described above. Do not use other types of batteries or rechargeable batteries. -

Page 14: Units
7-3. Units The most common unit of weight used around the world is the gram, but there is often a need to shift to alternative units specific to the country where the balance is used or to select modes such as counting or percent. The units and the order they appear in the display are as follows: Pound Ounce (avoir) -
Page 15: Selecting A Weighing Unit
7-4. Selecting a Weighing Unit Press the MODE key to select a unit. Each pressing switches the units available in the order The following sections are a description of the described on the previous page. three common units: g (gram mode), pcs (counting mode), and % (percent mode). -
Page 16: Counting Mode (Pcs)
7-6. Counting Mode (pcs) The balance weighs the sample pieces and calculates the unit weight. Using the sample unit weight, the balance counts the number of objects in the sample. As for the minimum unit weight acceptable, refer to the function setting “Umin” of “10-5. - Page 17 If the balance judges that the sample weight is too light to acquire accurate weighing data, it 50 - displays an error prompting the addition of more samples to the specified number. The displayed number Add the specified number of samples and press will be stored as the the PRINT key.

9. CALIBRATION This function adjusts the balance for accurate weighing. Perform calibration in the following cases. When the balance is first used. When the balance has been moved. When the ambient environment has changed. For regular calibration. Press and slide the calibration Calibration (CAL) switch cover down. - Page 22 Weighing 5. With Cal 0 displayed, press the PRINT key to calibrate the zero point. Do not touch the pan during zero calibration. When zero calibration has been completed, the balance displays the calibration weight value. With nothing on the pan If span calibration is not to be performed, press the MODE key or CAL switch to return to the...

Page 23: Gravity Acceleration Correction
9-2. Gravity Acceleration Correction When the balance is first used or has been moved to a different place, it should be calibrated using a calibration weight. But if a calibration weight is not available, the gravity acceleration correction will compensate the balance. Change the gravity acceleration value of the balance to the value of the area where the balance will be used. -

Page 29: Data Output Via Optical Signal
11. DATA OUTPUT VIA OPTICAL SIGNAL The EK-AEP series is equipped with an optical connector from which it can output weighing results to a device in a distant safe area via optical fiber cable and an AD-1611 optical communication adapter (both sold separately). - Page 30 Data format Header Data Unit Terminator (“ ” shows a space.) Separator There are four types of headers: ST : Stable weighing data (including % data) QT : Stable counting data US : Unstable weighing data (including counting and % data) OL : Out of weighing range (Over) The data is normally 9 digits including a decimal point and a sign.
- Page 31 Key mode Set the function to “prt 1, 2 or 3”. When the PRINT key is pressed while the weight data is stable (the STABLE indicator is on), the balance transmits the data. When the data is transmitted, the display will blink one time. Auto-print mode A Set the function to “prt 2”.

Page 32: Id Number And Glp
12. ID NUMBER AND GLP The ID number is used to identify the balance when Good Laboratory Practice (GLP) is used. The ID number is stored in memory even if power to the balance is turned OFF. The following GLP data is transmitted to a printer or a computer using the optional RS-232C serial interface. -
Page 33: Output Example
12-2. Output Example To print the GLP report, set the function to “info 1” and set the AD-8121B printer to MODE 3. To output the GLP report to a personal computer, set the function to “info 2”. Data format for “calibration report” Perform calibration using a weight. -
Page 34: Calibration Test Using A Weight
“Title block” and “End block” When weight values are recorded as GLP data, a “Title block” and an “End block” are added to the weight values for the GLP report. To output the GLP report to the AD-8121B printer, set the printer to MODE 3. 1. - Page 35 CC 0 2. CC 0 is displayed. 3. If it is necessary to change the target weight value that is used for calibration test, press the SAMPLE key and change the value using the following keys. SAMPLE key To select the digit to change the value (blinking). TARE key To change the value of the blinking digit.
- Page 36 13. OPTION As an option, a carrying case (EJ-12) is available for carrying the balance by hand. Please note that the balances are precision equipment and they, even placed in the case, will not be able to withstand excessive shock, such as being dropped. Therefore, use much care when carrying the balance.

Page 37: Maintenance
14. MAINTENANCE 14-1. Notes on Maintenance Do not disassemble the balance. . Use the original packing material for transportation. Do not use organic solvents to clean the balance. Use a lint free cloth moistened with warm water and a mild detergent. 14-2. - Page 38 CAL errors Calibration has been canceled because the calibration Cal e weight is too heavy. Calibration has been canceled because the calibration -Cal e weight is too light. Check the weighing pan and the calibration weight. To return to the weighing mode, press the MODE key.
