3. PRECAUTIONS To get the optimum performance from the balance and acquire accurate weighing data, note the following: 3-1 Before Use Install the balance in an environment where the temperature and humidity are not excessive. The best operating temperature is about 20°C / 68°F at about 50% relative humidity. Install the balance where it is not exposed to direct sunlight and it is not affected by heaters or air conditioners. Install the balance where it is free of dust. Install

This balance uses a strong magnet as part of the balance assembly, so please use caution when weighing magnetic materials such as iron. If there is a problem, use the underhook on the bottom of the balance to suspend the material away from the influence of the magnet. Cancel the temperature difference between a sample and the environment. When a sample is warmer (cooler) than the ambient temperature, the sample will be lighter (heavier) than the true weight. This error is due to a

3-6 Smart Range Function The GP-32K, GP-32KS and GP-102K are equipped with two ranges. The precision range has a higher resolution. The standard range has normal resolution. The range is switched automatically, depending on the value displayed. Pressing the RE-ZERO key allows weighing in the precision range, regardless of the tare value. (Smart range function) The range can be fixed to the standard range, by pressing the SAMPLE key. Note Once the range is switched to the standard range,

4. WEIGHING UNITS 4-1 Units With the GP series balance, the following weighing units and weighing modes are available : A unit or mode can be selected and stored in the function table as described in “4-2 Changing the Units”. If a weighing mode (or unit of weight) has been turned off, that mode or unit will be missing in the sequence. Tael has four varieties, one of which can be selected and installed at the factory. For details about the units and modes, see the tabl

5-2 Counting Mode (PCS) This is the mode to determine the number of objects in a sample based on the standard sample unit mass. Unit mass means the mass of one sample. The smaller the variables in each sample unit mass is, the more accurate the counting will be. The GP series balance is equipped with the Automatic Counting Accuracy Improvement (ACAI) function to improve the counting accuracy. Note If the sample unit mass variable, the difference from sample to sample, is too large, it ma
