Page 5: Introduction
1. INTRODUCTION This manual describes how this balance works and how to get the most out of it in terms of performance. The 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. -

Page 7: Setting Up
Replace used batteries with four new ones when “lb0” is displayed. Do not mix used and new batteries. Do not mix battery types. It may cause damage to the batteries or the balance. The battery life depends on the ambient temperature, how used and so on. -
Page 8: Breeze Break
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. -
Page 9: Operation
(About units: Only the available units will be displayed.) The display turns off except for a weighing unit and the decimal point. The balance waits for the weight value to become stable, and then, zero will be displayed with the ZERO indicator (power-on zero). -
Page 10: Units
“Newton” is the value calculated by “(weight in grams) x (9.80665 m/s ) / 1000”. The unit “t (tola)” and three kinds of “tl (tael)” are for special versions only. One of them can be selected and installed at the factory. -
Page 11: Selecting A Weighing Unit
In this case the ZERO and NET indicators turn on. Precautions during operation Make sure that the STABLE indicator is on whenever reading or storing a value. -
Page 12: Counting Mode (Pcs)
5-6. Counting mode (pcs) The balance weighs the sample pieces and calculates the unit weight. Using the sample unit weight, the scale counts the number of items in the sample. As for the minimum unit weight acceptable, see the function setting “Umin”. -
Page 13: Percent Mode (%)
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. -

+4d or less than -4d). d = the smallest display division. e.g.: 4d = four display divisions The upper limit and lower limit numerical values are common to each of the weighing, counting and percent mode. The example for EJ-120/200/300/410/610 is as follows. - Page 15 Entering the upper and lower limit values 6. With Cp Hi displayed, press the PRINT key. Cp Hi Enter the upper limit value using the following keys. SAMPLE key To select the digit blinking to be changed. RE-ZERO key To set the value of the digit 000000 selected.

Page 16: Calibration
1. Warm up the balance for at least half an hour with the CAL switch nothing on the pan. 2. Press and hold the calibration (CAL) switch until appears, and release the switch. Release the CAL switch 3. The balance displays Cal 0 . - Page 17 If the balance is to be moved to other places, set the gravity acceleration value of the area where the calibration using a weight is to be done, and calibrate the balance according to the procedure above. See the next section to set the value.

The balance transmits the weight data when the display is stable (the STABLE indicator is on) and the data is greater than +4d or less than -4d. The next output can be obtained after the display returns between -4d and +4d. -
Page 28: Ej-08 Underhook
By attaching the underhook to the bottom of the balance, large objects that are difficult to load on the weighing pan can be weighed, and the density (specific gravity) of objects may be measured. Refer to “9-6. EJ-13 Density determination kit” for information about density measurement. -
Page 29: Density Determination Kit
9-6. EJ-13 Density determination kit Using this option and calculation program, the balance can determine the density (specific gravity) of a sample. EJ-13 is for use with the EJ-120 / EJ-200 / EJ-300 / EJ-410 / EJ-610. EJ-13 Installation Fixing frame... - Page 30 (factory setting: 25 °C). 3.
