1. INTRODUCTION This manual describes how this balance works and how to get the most out of it in terms of performance. EJ series balances have the following features: The EJ series are high-resolution type electronic balances having a display resolution of 1/12,000 ~ 1/60,000. The balance has a counting function, % function and a comparator function. The backlight LCD will help with use in a dimly lighted place. The balance can be operated with an AC adapter, or 4 x “AA” size

4. SETTING UP 4-1. Setting up your balance 1. Place the weighing pan on the main unit as shown in “2. UNPACKING”. 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. CALIBRATION”) Balance location To measure correctly, to keep the balance in good condition, and to prevent hazards, observe the following: Do not install the balance in locations t

Remove batteries when the balance is not to be used for a long time. They may leak and cause damage to the balance. Damage due to battery leakage is not covered by the warranty. Installing batteries 1. Turn off the balance and disconnect the AC adapter if used. 2. Slide the battery cover off. 3. Push the battery box up to unhook and pull it out. 4. Insert new four batteries (LR6 / R6P / AA size) into the battery box, taking extreme care of the polarities. 5. Push the battery box int

(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 weighing data to become stable, and zero will be displayed with the ZERO indicator (power-on zero). The range for power-on zero is within

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) Metric carat Percent mode Momme Counting mode Pennyweight Gram Grain Newton Density (specific gravity) Among the units, those available for t

9. The balance re-calculates the unit weight while the ACAI indicator is blinking. Do not touch the balance or samples on the pan until the ACAI indicator turns off. 10. Counting accuracy is improved when the ACAI indicator turns off. Each time the above operation is performed, a more accurate unit weight will be obtained. There is no definite upper limit of ACAI range for the number of samples exceeding 100. Try to add the similar number of samples as displayed. 5-7. Percent mode

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). Co

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.
