9 3. PRECAUTIONS T o get the optimum performance from the balance and acqu ire 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 .
10 This balance uses a str ong magnet as pa rt 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.
11 3-5 Display Symbols and Key Operation Key operation Key operation affects ho w the balance func tions. The basic ke y operations are: “Press and release the key immediately” or “Pres s th.

16 4-2 Changing the Units The units or modes can be selected and stored in the function table. The sequence of displaying the units or modes can be arranged so as to fi t the frequency of use in the function table.
17 5. WEIGHING 5-1 Basic Operation (Kilogram Mode) 1 Place a container on the wei ghing pan, if necessary. Press the RE-ZERO key to c ancel the weight (tare). The balance displays 0. 0000 kg . (The decimal point position depends on the balance model.) 2 Place a sample on the pan or in the container.
18 5-2 Counting Mode (PCS) This is the mode to determine t he 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.
19 Counting operation 7 Place the samples to be counted on the pan. Note Up to 50 unit masses can be stored in memory fo r the multiple sample. For details, refer to “11.
20 5-3 Percent Mode (%) This is the mode to display t he weight value in percentage compared to a 100% reference mass and is used for target weighing or checking the sample variable. Selecting the percent mode 1 Press the MODE key to select % (percent mode).
21 5-5 Accumulation Function The accumulation function adds the weighi ng data and displays the total value. T o use the accumulation function, set the “Accumulation function ( add )” parameter of the function table as described below . Note While the accumulation function is in use, the data memory function is not available.
22 Using the accumulation function Use the keys below to operat e the accumulation function. MODE key: Displays the weighing data and the tota l value alternately each time it is pressed. Will not change the unit while the a ccumulation function is in use.
23 6. RESPONSE ADJUSTMENT / SELF CHECK FUNCTION This function detects the influence on weighing that is caused by drafts and/or vibrat ion at the place where the balance is installed and sets the response characteristic automatica lly . When this function is selected, the balance self-checks th e performance at the same time.
24 Notes If improper performance is found in the self check, the balance displays CH no . Contact the local A&D dealer for repair. If the automatic response adjustment fails, the balance displays CH ng . Check the ambient conditions such as breeze and vibration, al so check the weigning pan.
