2.5 Calibration Execution Menu

2.5.1 Calibration

Calibration is required to accurately weigh items with an electronic balance. Calibration should be performed:

• When the location of the balance is changed, even within the same room.

• When the room temperature changes considerably.

• Periodically, according to the quality control plan of the user.

Terms used in this manual:

Span Calibration: Adjustment of the balance to specifications using two weight

values; zero and an appropriate value for the balance capacity.

Calibration Check: Comparing the current calibration mass reading to the

calibration mass reading after the last span calibration.

PSC: Span Calibration is performed automatically using the built-in

calibration mass when the balance detects a temperature change that would affect weighing accuracy.

Clock-CAL: Span Calibration is performed automatically using the built-in

calibration mass at up to 3 specific, preset times during each day. The user selects the times.

PCAL: Procedure to calibrate the built-in calibration mass to an

external calibration mass standard. The PCAL procedure is password protected.

Factory Default Settings:

BX-K series Calibration using the external weight. ( ) BW-K series Calibration using built-in weights. ( )

The settings for the type of calibration can be changed with menu selection.

Section 2.6.1 "Selecting Standard Calibration Type."

Note: The following displays may appear in the situations listed.

When it takes too much time to stabilize the balance. When the zero point of the balance appears to have changed greatly. When the balance calibration appears to have changed greatly or

the wrong weight is loaded on the pan during calibration.

In all of these situations, span calibration or calibration check is not performed.

2.7 Graphic Display Menu

2.7.1 Overview

The BX-K and BW-K series balance has a bar graph located on the left side of the display. This graph can be conveniently used for liquid weighing and pass or failure judgment (comparator function) of the sample. The graphic display functions include the Full Scale mode, Target mode, Group mode, Level mode, and no graphic display mode.

Note: Target, limit, upper, and lower values are set as numeric values only. Set the correct

numeric value for the unit that will be used for weighing.

• In weighing mode, changing the displayed unit does NOT change the target, limit, upper, or lower numeric values. For example, when the upper limit has been set at 10g, switching the unit from “g” to “kg” does not change the limit to 10kg. It will be 0.01kg.

• The decimal point is invisible in the value setting display. Determine its position based on the resolution of the balance. For example, if the balance’s minimum display is 0.01g, 150g must be set by inputting “15000” in the display.

• Numeric values are memorized independently for each graphic display mode.

• The graphic display mode can be selected without setting numeric values.



2.7.2 Full Scale Mode

The relative amount of the load on the pan is displayed in the bar graph. This feature helps to prevent errors due to OL (overload) status. Use Menu Map item [11] to select the Full Scale mode. A bar displayed in the lower areas of the scale indicates that the load on the pan is small. A bar displayed in the upper areas of the scale indicates that the load on the pan is close to the weighing capacity.

2.7.3 Target Mode

Target mode is useful for filling applications or for quality check by weight. The used for weighing. The

value is the numeric value that is the desired amount in the unit that is

value is the numeric amount above or below the target value that is acceptable. This mode is useful for constant amount weighing of liquid or judgment of excess and shortage.

Application Measurement function cannot be selected while %, PCS, or specific gravity units are displayed.

2.9.2 Zero Range

The "Zero Range" value is used in the Application Measurement function as a reference to identify whether the sample is loaded. For example, if the display is within the Zero Range, the balance determines that a sample is not loaded. If the display is more than five times the Zero Range it determines that a sample is loaded. Application Measurement functions which involves judgment of whether a sample is loaded or not work in accordance with the Zero Range setting. In Menu Map item [48], the "Zero Range" value is set using the number of counts displayed in kilogram-display. The setting range is 01 to 99 with 01 being the default value. Even when weighing will be

done in another unit, Zero Range setting is made by only gram value.

(2) Commands that end with a [=]: Transmit the number to the balance with a

delimiter. Example 2: TIME=1234 <CR> .. 12:34 is set as the current time. Example 3: P.TARE=1.23 <CR> (example of type of the second

decimal place). …1.23g is set as a Pretare value.

Example 4: P.TARE=0.00 <CR> (example of the second decimal

place) …Clears (cancels) the Pretare value.

Note: Number of digits, decimal point, position of decimal point of the numeral

transmitted succeeding to '=' are the same as the case of setting the numeric value using the AKB-301 Application Keyboard. Number of digits below the decimal point is as follows.

S-type and H-type: Use the same number of decimal places as

in the gram-display.

This restriction does not apply to USER=, SOLID=, and LIQUID=.

'2-56<CR>' and '12-345-67<CR> are output from the balance.

(3) Echo back command

The balance again transmits the character strings of N pieces included between an echo back command '{' or '}' and the delimiter. An unprocessed echo back command is not left in the receiving buffer of the balance, N≤30. Example 8: ABCDEFG12345<CR>

... After receiving this command, the balance outputs ABCDEFG12345<CR>. The printer can print this character string.

Windows®* = Windows 95, Windows 98, Windows Me, Windows 2000

When the Function Intermittently Malfunctions:

• Use a communication speed of 300bps. Depending on the processing ability of the PC, this function may operate incorrectly if communication speed is too high.

• Send the next data only after the current one is displayed on the screen. Depending on the processing ability of the PC, this function may operate incorrectly if interval of data transmission is too short.

• Do not touch the keyboard or the mouse while the balance is transmitting data.

Stop the data transmission and confirm that no data is entering the PC before

touching the keyboard or the mouse.

• This operation may be incorrect when the displayed value is not a weight value (i.e. error code or time).

• The unit designation is not transmitted.

• This function may operate incorrectly depending on the settings of various lock keys of the keyboard such as the NUMLOCK or cursor key lock. Change the state of the lock and function keys on the PC keyboard.

• The peripheral devices connected to the DATA I/O such as Electric Printer EP-50 cannot be used with this function.

• When this function is used, a command cannot be sent from the peripheral device to the balance.

• Set the data formats, such as decimal places and units, in each application.

3.2.5 Multi-Connection Mode



A maximum of 26 BX-K/BW-K series balances can be connected to one personal computer at the same time. This is called "Multi-Connection mode." To use the balance in this mode, prepare RS-232C cables in the number of balances connected, and the optional IFB-102A RS-232C Interface.

Connecting Method Example for connecting 10 units of BW/BX series balances to one personal computer is shown in the diagram below.

Assignment of Identification Name In this example (10 balances connected to one computer), assign the identification name in lower-case alphabets. Since 10th character of alphabet is "j," assign "j" to the balance closest to the personal computer, "i" to next closest balance, and so on, back to "a." Setting to Multi-Connection Mode

1) Adjust the communication menu settings of all the balances to the specification of the personal computer, and then, turn off the power to all balances.

2) Start supplying the power to the whole system. Wait until all balances display OFF.

3) Send "[α] <delimiter>" from the personal computer. α is the name of the balance next to the personal computer. In the example above, lower-case "j." This command is valid only one time after turning the power ON. Respective balances automatically enter the Multi-Connection mode and the mass is displayed. On this process, the name smaller than the sent command by one, i.e. "[i] <delimiter>", is returned.

4) This procedure completes the setting to the Multi-Connection mode.

Restricted Items in the Multi-Connection Mode

Multi-Connection mode is not designed for each balance to independently send the data. This mode is for sampling the data by control of multiple balances with one PC. This is not the function to support multiple balances for sending the data separately. When multiple number of data and commands exist on the system at the same time, the balance may not operate normally. For example, multiple data may exist simultaneously on the system when using multiple balances in the Application Measurement mode such as Auto Print or Continuous Output, or pressing the

key. Normal operation cannot be guaranteed. Peripheral instruments connected to the DATA I/O or IFB-102A connector, such as an EP-50 Electronic Printer, cannot be used. The communication formats can only be used with used with

Cancellation of Multi-Connection mode

Multi-Connection mode cannot be canceled unless the power for all balances is turned OFF.
