Describes precautions on handling the construction and basic balance operation. balance, balance Adapting to the environment ....
2. UNPACKING THE BALANCE 2-1 Unpacking The balance is a precision instrument. Unpack the balance carefully. Keep the packing material to be used for transporting the balance in the future. The packing contents depend on the balance model. See the illustrations to confirm that everything is contained. How to assemble the breeze break (Only for FX-120i/200i/300i) Assemble the breeze break as shown below. Follow the numbered sequence.
2-2 Installing the Balance Install the balance as follows: 1. Place the balance on a solid weighing table. Refer to “3. PRECAUTIONS” for installing the balance. 2. FX-120i /200i /300i Assemble the pan support, weighing pan and breeze break, on the balance as shown in the illustration on page 4. FX-1200i /2000i /3000i Assemble the pan support and weighing pan on the balance as shown in the illustration on page 4. 3. Adjust the leveling feet to level the balance. Confirm it using the bubble spirit level. 4.
3. PRECAUTIONS To get the optimum performance from the balance and acquire accurate weight 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.
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. Eliminate 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.
3-5 Display Symbols and Key Operation Key operation Key operation affects how the balance functions. The basic key operations are: “Press and release the key immediately” or “Press the key” = normal key operation during measurement “Press and hold the key” Display symbols Each key, when pressed or when pressed and held, functions as follows: Key When pressed When pressed and held Turns the display on or off. The standby indicator is displayed when the display is turned off.
4. WEIGHING UNITS 4-1 Units With the FX-i 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 on page 11. 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. To select a unit or mode for weighing, press the MODE key.
The tables below indicate the weighing capacity and the minimum display for each unit, depending on the balance model.

4-2 Storing 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 in the function table so as to fit the frequency of use. Select a unit or mode and arrange the sequence of display as follows: 1 Press and hold the SAMPLE key until function table is displayed. ba5fnc of the 2 Press the SAMPLE key several times to display 1Unit . 3 Press the PRINT key to enter the unit selection mode.
5. WEIGHING 5-1 Basic Operation (Gram Mode) 1 Place a container on the weighing pan, if necessary. Press the RE-ZERO key to cancel the weight (tare). The balance displays 0.00 g. (The decimal point position depends on the balance model.) 2 Place a sample on the pan or in the container. 3 Wait for the stabilization indicator to be displayed. Read the value. While the stabilization indicator is on, pressing the PRINT key will output the weight value, using the RS-232C serial interface.
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 are, the more accurate the counting will be. The FX-i series balance is equipped with the Automatic Counting Accuracy Improvement (ACAI) function to improve the counting accuracy. Note If the sample unit mass variable is too large, it may cause a counting error.
If the balance judges that the mass of the samples is too light to aquire accurate weighing, it displays an error requiring the addition of more samples to the specified number. In the example above, 150- PCS appears, requiring 25 more samples. Add 25 samples and press the PRINT key. When the unit mass is stored correctly, the balance proceeds to the counting mode. Counting operation 7 Place the samples to be counted on the pan.
5-3 Percent Mode (%) This is the mode to display the 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). Storing the 100% reference mass 2 Press the SAMPLE key to enter the 100% reference mass storing mode. Even in the storing mode, pressing the MODE key will switch to the next mode. 3 Place a container on the weighing pan, if necessary.
5-4 Statistical Calculation Mode The statistical calculation mode statistically calculates the weight data, and displays or outputs the results. To use the statistical calculation mode, set the "Application function (apf)" parameter of “Application (ap fnc)” in the function table to “2”, as described below. Statistical items available are number of data, sum, maximum, minimum, range (maximum-minimum), average, standard deviation and coefficient of variation.
Selecting the statistical items to output 5 Press the SAMPLE key to display 5taf 0 . 6 Press the RE-ZERO key to select the output items. In the example, 5taf 1 is selected to output the number of data, sum, maximum, minimum, range (maximum-minimum) and average.

9-5 Description of the Item “Data Output Mode” The parameter setting of the “Data output mode ( prt )” applies to the performance when the data is transmitted using the RS-232C serial interface. Key mode When the PRINT key is pressed with the stabilization indictor turned on, the balance outputs the weight data and the display blinks one time.
Interval output mode The weight data is periodically output. When the PRINT key is pressed, the balance starts to output the weight data at a preset interval time. When the PRINT key is pressed again, the balance stops outputting the weight data. Required setting Example dout prt 6 Interval output mode dout int Interval time “For outputting the weight data periodically." Caution The balance may not transmit the data completely at the specified interval times and baud rate. Set the baud rate higher.
KF format 5if type 2 This is the Karl-Fischer moisture meter format and is used when the peripheral equipment can only communicate using this format. This format consists of fourteen characters excluding the terminator. This format has no header characters. The polarity sign is placed before the data, with spaces in place of leading zeros, if the data is not zero or overloaded. This format outputs the unit only for a stable value.
9-7 Data Format Examples
Note When “Pound Ounce” is selected, the data is output with the unit of ounce (oz). 9-8 Description of the Item “Application Function” Capacity indicator ( apf 1) In the weighing mode, the indicator displays the weight data relative to the weighing capacity in percentage. (Zero = 0%, maximum capacity = 100%) Statistical calculation mode ( apf 2) The mode statistically calculates the weight data, and displays or outputs the results. For details, refer to “5-4 Statistical Calculation Mode”.
9-9 Comparator Function The results of the comparison are indicated by HI OK LO on the display.
10. ID NUMBER AND GLP REPORT The ID number is used to identify the balance when Good Laboratory Practice (GLP) is used. The ID number is maintained in non-volatile memory even if the AC adapter is removed. The GLP output format is selected at “GLP output (info)” of the function table and can be output to a personal computer or printer using the RS-232C serial interface.
