5. OPERATION 5-1. Turn the power ON and OFF 1. Press the ON:OFF key to turn the power ON. STABLE Weighing units ZERO 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. -
Page 10: Units
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) -
Page 11: Selecting A Weighing Unit
5-4. Selecting a weighing unit Press the UNITS key to select a unit. The following sections are a description of the Each pressing switches the three common units: g (gram mode), pcs (counting units available in the order described on the previous mode), and % (percent mode). -
Page 12: Counting Mode (Pcs)
5-6. Counting mode (pcs) Weighs the sample pieces and calculate its unit weight. Using the sample unit weight, the scale counts the number of parts or items. As for the minimum unit weight acceptable, see the function setting “Umin”. Selecting the counting mode 1. -
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. -

= 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. Upper limit value “001010”: “10.10g” “1010pcs” “101.0%”... - Page 15 Entering the upper and lower limit values Cp Hi 6. With Cp Hi displayed, press the PRINT key. Enter the upper limit value using the following keys. SAMPLE key To select the digit blinking to change. RE-ZERO key To set the value of the digit 000000 selected.

7. CALIBRATION This function adjusts the balance for accurate weighing. Perform a calibration in the following cases. Calibration (CAL) switch When the balance is first used. When the balance has been moved. For regular calibration. Calibration (CAL) switch cover 7-1. Calibration using a weight Prepare the calibration weight (sold separately) in advance. - Page 17 5.

Page 18: Gravity Acceleration Correction
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. -

9-3. EJ-07 / 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 the “9-6. EJ-13 Density Determination Kit” for the information about the density measurement. -
