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.
3. PART NAMES AND FUNCTIONS Outputs the weight data to Turns the power on or off. a printer or computer, or enters a unit weight, 100% weight or other setting Held down to enter the function values to the balance.
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 that are subject to excessive dust, breezes, vibration, large temperature fluctuations, condensation, or that may have magnetic fields.
(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).
+2% of the weighing Stability mark capacity, it will be subtracted to zero as a tare weight. In this case the ZERO and NET marks turn on. Precautions during operation Make sure that the stability mark is on whenever reading or storing a value.
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.
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 :pieces) Storing the sample unit 2.
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.
= 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. An example for the EK-1200i/2000i/3000i is as follows. Upper limit value “001010”: “101.0g” “1010pcs” “101.0%”...

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.
Press and hold 1. Press and hold the calibration (CAL) switch until Cal the CAL switch. appears, and release the switch. 2. The balance displays Cal 0 .
Cancels the operation and turns off the balance. Item key Selects a class and an item. In the weighing mode, press and hold the key to enter the function setting mode. Enter key Proceeds to the selected class. Stores the settings per class and goes to the next class.

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”.

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 Press and hold both keys.

It is possible to sound a buzzer according to the comparison result. See the function “bep” to set which result will make a buzzer sound. The comparator function on/off, the comparison mode and comparator buzzer output can be selected using the function settings.
OP-04 Installation 1. Remove the cover of the option slot on the rear of balance by pressing and lowering it down. 2. Insert the option into the slot and secure it with the screws attached. 11-2. OP-07 Underhook assembly By attaching the underhook assembly to the bottom of the balance, large objects that are difficult to load on the weighing pan can be weighed in suspension, and the specific gravity of objects may be measured.
