Page 5: Introduction
EK-i and EW-i series balances have the following features: q The EK-i series are high resolution type electronic balances having a resolution of 1/6,000 ~ 1/30,000. q The EW-i series are triple range balances and each range has a resolution of 1/3,000. -

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. -
Page 8: Operation
5. OPERATION 5-1. Turn 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 weighing data to become stable, and zero will be displayed with the ZERO mark (power-on zero). -
Page 9: 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) -

9. The balance re-calculates the unit weight while the ACAI mark is blinking. 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. Each time the above operation is performed, a more accurate unit weight will be obtained. -

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 “ ”): q No comparison (comparator function disabled). - Page 15 Entering the upper and lower limit values Cp Hi 6.

Page 18: Functions
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. -
