1. INTRODUCTION This manual describes how this balance works and how to get the most out of it in terms of performance. The EK-i and EW-i series balances have the following features: The EK-i series are high resolution type electronic balances having a resolution of 1/6,000 ~ 1/60,000. The EW-i series are triple range balances and each range has a resolution of 1/3,000. The balance has a counting function, % function and a comparator function.
3. PART NAMES AND FUNCTIONS Turns the power on or off. Held down to enter the function setting mode. Weighing mode (EW-i only): Changes the weighing range (when rng 0 is selected). pcs mode: Enters the sample unit weight storing mode. % mode: Enters the 100% weight storing mode. 4 Outputs the weight data to a printer or computer, or enters a unit weight, 100% weight or other setting values to the balance. Switches the weighing unit (the weighing mode). Clears the display to zero.
4. SETTING UP 4-1. Setting up your balance 1. Place the weighing pan on the main unit as shown on the previous page. 2. Adjust the level of the balance using the leveling feet. Use the spirit level to confirm. The bubble should be in the center of the circle. 3. Calibrate your balance before use. (See “7.
5. OPERATION 5-1. Turning the power ON and OFF 1. Press the ON/OFF key to turn the power ON. All of the symbols are displayed as shown above. (About units: Only the units available will be displayed.) The display turns off except for a weighing unit and the decimal point. The balance waits for the weight data to become stable, and zero will be displayed with the ZERO mark (power-on zero). The range for power-on zero is within ±10% of the weighing capacity around the calibrated zero point.
5-3. 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) Percent mode Troy ounce Counting mode Metric carat Gram Momme Pennyweight Tael Grain Among the units, those available for the user have been set at the factory before shipping.
5-4. Selecting a weighing unit Press the MODE key to select a unit. The following sections are a description of the three common units: g (gram mode), pcs (counting mode), and % (percent mode). Each pressing switches the units available in the order described on the previous page. ZERO 0.0 Stability mark 5-5. Basic operation 1. Select a weighing unit. 2. When the display doesn’t show zero, press the RE-ZERO key to set the display to zero. Container 3.
5-6. Weighing range for the EW-i series The EW-i series have three weighing ranges, and the display shows which range the weight value belongs to with the mark R1, R2 or R3. There is a function setting to select how the weighing range changes. Select from automatic range (rng 1), manual range (rng 0) or fixed range (rng 2 to 4).
5-7. Counting mode (pcs) Determines the number of objects in a sample. Calculates the reading, using the basic sample unit weight, and determines how many pieces are contained. Selecting the counting mode 1. Press the MODE key to select 0 . ( :pieces) Storing the sample unit 2. Press the SAMPLE key to enter the sample unit weight storing mode. 10 - 3. To select the number of samples, press the 1SAMPLE key. It may be set to 5, 10, 25, 50, or 100. Switches the number of samples. 4.
8. After setting the unit weight at step 6, add a few more samples on the pan. Then, the ACAI mark will turn on. (Add more than three pieces. The mark will not turn on for the number of samples beyond the ACAI range.) 9. The ACAI mark will blink and the balance re-calculates the unit weight. Do not touch the balance or samples on the pan until the ACAI mark turns off. 10. Counting accuracy is improved when the ACAI mark turns off.
6. COMPARATOR The results of the comparison are indicated by HI, OK or LO on the display. The comparison is as follows: LO < Lower limit value ≤ OK ≤ Upper limit value < HI Operating conditions (see the function setting “Cp”): No comparison (comparator function disabled). Compares all data. Compares all stable data. Compares plus data except those near zero (plus data greater than +4d). Compares stable plus data except those near zero (stable plus data greater than +4d).
Entering the upper and lower limit values 6. With Cp Hi displayed, press the PRINT key. Enter the upper limit value using the following keys. SAMPLE RE-ZERO key key To select the digit blinking to change. To set the value of the digit selected. Hold down the key to switch the sign “+” and “-“. (“N” designates a negative value.) PRINT key To store the value and proceed to the next step. MODE key To cancel the value and proceed to the next step. 7. With Cp lo displayed, press the PRINT key.
7. 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. 7-1. Calibration using a weight Prepare a calibration weight (optional) before start. 1. Warm up the balance for at least half an hour with nothing on the pan. 2. Press and hold the calibration (CAL) switch until Cal appears, and release the switch. 3.
5. At step 3, pressing the PRINT key weighs the zero-point value. Do not touch the pan during weighing. When the zero calibration is completed, the display shows the calibration weight value. Weighing pan With nothing on the pan To perform the zero calibration only and finish the procedure, press the MODE key. To store Cal 0 1000.0 Calibration weight 6. Place the calibration weight with the same value as displayed on the pan. Press the PRINT key to weigh it. Do not touch the pan during weighing.
7-2. 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 the calibration weight cannot be prepared, 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. See the gravity acceleration map appended to the end of this manual.

9. RS-232C SERIAL INTERFACE This interface allows the EK/EW-i series to be connected with a multifunction printer or a personal computer. The RS-232C interface has the following four modes. Stream mode Outputs data continuously. Key mode Outputs data by pressing the PRINT key. Auto-print mode Outputs data which meets the conditions of auto-print. Command mode Controls the balance using commands from a computer.
9-2. Data format S T , + 0 0 0 Header 0 0 . 0 0 g CR LF Data Unit Terminator (“ ” shows a space.) Separator There are four types of headers: ST : Stable weight data (including % data) QT : Stable counting data US : Unstable weight data (including count and %) OL : Out of weighing range (Over) The data is normally 9 digits including a decimal point and a sign.
Key mode Set the function “prt 1, 2 or 3”. When the PRINT key is pressed while the weight data is stable (the stability mark 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 “prt 2”. The balance transmits the weight data when the display is stable (the stability mark is on) and the data is greater than +4d (of the lowest range for EW-i series). The next output can be obtained after the display returns below +4d.
10. ID NUMBER AND GLP The ID number is used to identify the balance when Good Laboratory Practice (GLP) is used. The following GLP data is transmitted to an AD-8121 printer or a computer using the RS-232C interface. The result of calibration (“Calibration report”) The result of calibration test (“Calibration test report”) The “Start block” and “End block” for GLP data 10-1. Setting the ID number 1. Press and hold the func . SAMPLE Press and hold key to display func 2. Press the SAMPLE id . 3.
10-2. GLP report To print the GLP report to the AD-8121B, select the function setting “info 1” and “pUse 1” for the balance, and use MODE 3 of the printer. To transmit the GLP report to a personal computer, select the function setting “info 2” and “pUse 0”. The serial number attached to the lateral side of the balance may have a form “#Q1234567” (# = I, E and so on). In this case, the first letter “#” is ignored as a GLP data and output data has a form “Q1234567”.
Calibration test report The calibration test mode is used to compare a calibration test weight with the calibration test data weighed by the balance. This test does not perform calibration and this mode is available even after sealing the calibration (CAL) switch. 1. Press and hold the SAMPLE and PRINT keys. CC will appear. Then, release both keys. Pressing and holding the calibration (CAL) switch will also display CC after Cal . Then, release the CAL switch while showing CC . 2.
