Page 5: Precautions On The Use
1. Precautions on the Use • This Section "Precautions Relating to Use" sets forth precautionary notes that the user should observe in order to prevent physical injury to the user and/or damage to property. • The nature of problems that may result in the event of improper operation, and consequential effects on the quality and performance of the balance, are indicated under the two categories of "Caution"... - Page 6 Do not place the balance on an unstable base or use the balance in a location where it may be subjected to shock. • The loaded sample may fall off the measurement pan. Do Not Use • Accurate measurement may be rendered impossible.
- Page 7 Avoid applying excess force or impact to the balance. • Place the sample to be measured on the balance carefully to prevent breakage or Do Not Apply malfunction. Force Do not use the balance in a location were it may be subjected to abrupt changes in ambient temperature or humidity.

Operation Check Turning on the power When the balance has the AC adapter connected, it displays [ ]. Pressing the On/Off The display section lights up, and the balance is ready for operation. Checking the display Check to see if the display has any missing indications or unlit parts. -
Page 13: Operation For Tare Subtraction
3.3 Operation for Tare Subtraction Place the tare (container) on the balance. As you place the tare, the balance indicates its weight. Reset read-out indication to zero. Press the Zero/Tare key. The tare is subtracted and the balance indicates zero. ... - Page 14 Key Points of the Procedure The following applies equally to all the measurement modes for weight measurement, counting, and percentages. After the balance is switched off, there is still enough current to display [ ]. This indicates that the AC adapter is connected to an electrical outlet, but that the balance is turned off. When the balance is switched on again, [ ] will disappear.

Page 20: Counting Pieces
6. Counting Pieces To implement piece-counting, the specified samples are loaded on the balance, and their average unit weight (hereinafter, simply the “unit weight”) is entered and saved. The procedure for saving unit weights is called sampling. The counting procedure consists of loading articles that have already been sampled on to the balance. The number of pieces is then calculated by dividing the total weight of the loaded articles by the unit weight saved in memory. - Page 21 Changing the sampling number, if necessary. If samples to be counted widely deviate in weight, or a higher measure of How to change the value accuracy is desired, it is recommended that users change the sampling number to a larger value.

Page 23: Measuring Percentage
7. Measuring Percentage The percentage measurement function operates by weighing an actual sample, selected as the reference, and saving its weight as the reference value and indexing it as 100%. When a measurement sample loaded on the balance is lighter or heavier than the reference, its weight is indicated as a percentage (%) value relative to the reference weight. - Page 24 Key Points of the Prcedure While samples are being saved, the value indication disappears temporarily, and only the [M] mark flashes. If the balance is affected by wind or other vibrations during this process, the saving time may be prolonged. ...

Page 30: Calibrating The Balance
9. Calibrating the Balance Calibration is possible only when the balance is unsealed. Since electronic balances are affected by gravity gravitational acceleration, they produce different values in various locations. Therefore, before use, balances must be calibrated at the location where they are installed. - Page 31 Calibrating the Balance (cont.) Calibrating the capacity point Load the calibration weight in the center of the balance. The display flashes, indicating that capacity point calibration is in progress. Terminating the span adjustment When the calibration of the capacity point is finished, the original measurement mode is restored.
