For details, refer to the function setting “ltUp” of “10-5. Function List.” d=minimum display division, refer to “13. SPECIFICATIONS.” e.g.: “d” for the EK-300EP is 0.01 g. Therefore, 4d is 0.04 g. -
Page 13: Units
7-3. 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: Troy ounce Pound... -
Page 14: Selecting A Weighing Unit
7-4. Selecting a Weighing Unit Press the MODE key to select a unit. Each pressing switches the units available in the order The following sections are a description of the described on the previous page. three common units: g (gram mode), pcs (counting mode), and % (percent mode). -
Page 15: Counting Mode (Pcs)
7-6. Counting Mode (pcs) The balance weighs the sample pieces and calculates the unit weight. Using the sample unit weight, the balance counts the number of objects in the sample. As for the minimum unit weight acceptable, refer to the function setting “Umin” of “10-5. - Page 16 If the balance judges that the sample weight is too light to acquire accurate weighing data, it 50 - displays an error prompting the addition of more samples to the specified number. The displayed number Add the specified number of samples and press will be stored as the the ENTER key.

Page 18: Comparator
Compares stable data except those near zero (stable data greater than +5d or less than -5d). d = minimum display division. e.g.: “d” for the EK-300EP is 0.01 g. Therefore, 5d is 0.05 g. The minimum display for the counting mode is 1 piece, for the percent mode, 0.1%. - Page 19 Press 4. Press the TARE key several times to display several times 5.

Page 20: Calibration
9. CALIBRATION This function adjusts the balance for accurate weighing. Perform calibration in the following cases. When the balance is first used. When the balance has been moved. When the ambient environment has changed. For regular calibration. Press and slide the calibration Calibration (CAL) switch cover down. - Page 21 Weighing 5. With Cal 0 displayed, press the ENTER key to calibrate the zero point. Do not touch the pan during zero calibration. When zero calibration has been completed, the balance displays the calibration weight value. With nothing on the pan ...

Page 22: Gravity Acceleration Correction
9-2. 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 a calibration weight is not available, 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. -
