2-2. Precautions before use (Installation considerations and preparation) Prepare the following installation conditions in order to bring out the full performance of the balance. This product is a high precision balance with a maximum resolution of 1/600,000. The balance tends to be susceptible to temperature changes, pressure fluctuations, vibration, drafts, and other factors at the installation site.
Page 14 If the balance is moved, it may be damaged by impact shocks. In addition, the weighing value will be  unstable immediately after the balance is moved. Avoid sudden movements, stops, or impact shocks, and provide a sufficient waiting time for the weighing value to stabilize when acquiring weighing data. The moving device should have a structure where the balance can be kept level.
Page 15: Precautions During Use (For More Accurate Weighing)
2-3. Precautions during use (for more accurate weighing) For precise and accurate weighing, please take notice of the following. Metal case Weighing errors may occur due to the influence of static electricity. Note that if the ambient humidity drops below 45 %RH, Charged sample insulators such as plastics are liable to have static electricity.

Press the TARE to display (The decimal separator position depends on the balance model.) Sample Place a sample on the weighing pan or in the container.
Page 31 Zero-point setting, tare subtraction operation, and weighing range At the start of weighing The balance determines the reference zero-point when the power is turned on with the ON:OFF key. Depending on the load condition at that time, the balance will automatically judge whether to perform zeroing or tare subtraction operation.
Page 32: Counting Mode (Pcs)
4-3. Counting mode (PCS) This is the mode to determine the number of objects in a sample. Based on the reference sample unit weight (weight per piece), the balance calculates and displays how many pieces the sample weight corresponds to. The smaller the variation in the unit weight of sample pieces is, the more accurate the count will be.
Page 33 Automatic Counting Accuracy Improvement (ACAI) Processing indicator This function automatically improves the counting accuracy each time the number of sample pieces is increased. (Errors will be reduced as variations in sample weight are averaged.) After storing the unit weight in step 6, proceed to step 8 below. Add a few sample pieces.
