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:

CBX-K series Calibration using the external weight. ( )
CBW-K series Calibration using built-in weights. ( )

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

2.7 Graphic Display Menu :

2.7.1 Overview

The CBX-K and CBW-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 T arget Mode

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

40

The value is the numeric value that is the desired amount in the unit that is used for
weighing. The

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.

Menu Map item [12] selects the Target mode.
Menu Map item [13] sets the

value, which corresponds to the center line of the

graphic display.

Menu Map item [14] sets the

value, which corresponds to the distance between the

center line and upper or lower triangles.

2.7.4 Group Mode

This is the best mode to determine pass or failure judgment based on the sample weight.

Menu Map item [15] selects the Group mode.
Menu Map item [16] sets the upper threshold value, which corresponds to the upper triangle.
Menu Map item [17] sets the lower threshold value, which corresponds to the lower triangle.

2.8 Environment Menu :

2.8.1 Overview

Settings on the balance can be changed to compensate for the installation environment such as the
degree of vibration etc. or for the purpose of weighing a solid, liquid or powder.

2.8.2 Averaging

It is possible to match the stability of the display and the degree of response with the requirements of
specific applications.

Menu Map item [22] (Environment/Averaging-AUTOmatic)

The balance automatically performs optimum averaging dynamically while
observing the load data. This is the recommended setting and should be
used unless special circumstances exist.

Menu Map item [23]

(Environment/Averaging-POURing)
This mode is only suitable for constant volume weighing of liquids etc. This
mode is very sensitive to wind and vibration.

Menu Map item [24]

(Environment/Averaging-STaNDard)
This mode is suitable for weighing in a normal environment. Averaging is
fixed and does not change dynamically as in

.

Menu Map item [25] (Environment/Averaging-VIBRation)

Use this mode when the balance is used in a location where there are large
vibrations and the display fluctuates in the

mode.

Response time is deteriorated by small mass amount changes.

Menu Map item [26]

(Environment/Averaging-WIND)
Use this mode when the balance is used in a location where it is exposed to
airflow that causes the display to fluctuate in the

mode.
Response time deteriorates further than , but weighing is
comparatively stabilized.

Note: If weighing cannot be performed efficiently even with

, change the

installation site of the balance or use the deluxe windbreak or large pan windbreak.

2.8.3 Stability Detection Band

Menu items [27] to [33] are used to determine the conditions for indicating balance stability.

(Environment/Band-1):
When the display has remained constant (within one display count), the balance is regarded as stable
and the stability symbol illuminates. Stability detection band settings can be selected from
to

.

Note: Use

to only when the Auto Print function is used and it is
therefore required that the sensitivity to vibration be reduced to allow the balance to be regarded as
stable and print the measurement value.
The balance may not operate properly if these settings are selected under normal use conditions and
environment.

as long as possible. "Zero tracking" automatically cancels small zero drift.

It is recommended to set to

when measuring slight mass change such as in the

process of drop addition or liquid evaporation.

2.8.5 Pretaring V alue

This function is used to weigh the mass of a sample packed in a container such as a bottle or bag
without opening the container. Pretare function should be used only if the mass of the containers does
not vary from sample to sample. Instead of zero the pretare value is displayed (as a negative value)

when the

key is pressed. The pretare value is then subtracted from the load on the

balance pan to determine the weight of the sample.
Menu Map item [36] opens the Pretare setting screen.

Set the Pretare value using the

key and key, and press the key.

Pretare Value

Cancel the Pretare value by setting the value to zero.
When a Pretare value other than zero has been set,

2.9 Application Menu :

2.9.1 Overview

The Application Measurement function is the generic name of the functions used to perform
measurement work using the balance in more efficient ways. Only one Application Measurement
function can be used at a time. When the power is turned ON, the balance will begin in the function
mode that was last set.

Cancellation of Application Measurement

To cancel the Application Measurement, press the key while in the mass display and hold it

until

To use the Application Measurement function that was just canceled, use the last menu recall

function by pressing and holding the

key for 3 seconds in the mass display.

Using the Application Measurement Function with a Unit Other Than "kg"

Select the Application Measurement function while in the mass display, and select the unit of

weighing with the

key.

Because the operation of the

differs from the one in normal mass display, the 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.

Note: When a Pretare value is set, the value to determine that there is "no load" becomes

"- Pretare ± Zero Range" during mass display. For example, the Zero Range function works as
expected when attempting to weigh and Auto Print the mass of a bottled sample during mass display.

45

2.9.3 Auto Zero

the data output is slow, the display may flash. Increase the transfer speed as much as possible and set
the handshake to .

Menu Map item [47]

(on / go)
When the graphic display is in Comparator mode (Group mode or Level
mode) and the stability symbol lights in the GO range, the data is output
once.
The next data output is executed after the displayed value is within the Zero
Range.

2.9.5 Peak Hold

Menu Map item [49] measures the displayed peak value. The symbol is illuminated when the Peak
Hold function is activated.
"Peak value" is the highest or lowest stable value displayed after the display has changed beyond five
times the Zero Range.

3.2.3 Using Command Codes

Note: If communication conditions are incorrectly set, a communication error is

displayed.

(1) Commands that end with a number, character, or symbol other than [=]: Transmit to the balance

with a delimiter for each command code.

Example 1: PRINT<CR> ... The same operation as pressing the

key

(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=.

Example 5: MENU=4630 <CR> (4-digit number after [=])

This is the same in the following operation.

... from mass display, press the

key four times, the press the

key once and the press the

key six times. This returns to the same display

as if the

key was never pressed.

Press the

key once, the key three times, and the

key once more.

This example indicates that

is selected.

Note: If there is 0 in the four-digit number, the setting is complete at that point and menu selection is

ended.
The result of this command varies depending on the type of the balance.

60

Example 6: #=2.56 <CR>
Example 7: #=12.345.67 <CR>

A personal computer can instruct the weighing and display a specific number on
the balance.
With the commands in Example 6 &7, [#2.56] and [#12.345.67] are displayed on

the balance. When the operator presses the

key, the character string '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.

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.

Format of Output Data from the Balance

The output data from the balance "α" is performed with the following format.
"[α]" data <delimiter>
Format of the load data is the same as the normal output form (

).
Operation is not guaranteed for the data containing characters, such as printing of date, time, and
calibration document etc.

Restricted Items in the Multi-Conne ction 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

. Delimiters cannot be used with

or .
It will take an average 0.05 x N seconds for the data from the personal computer to reach balance unit
N, even at setting of 38400 bps. Also, it will take almost the same time for the data from the balance
in the Nth position to reach the personal computer.

Cancellation of Multi-Connection mode

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

This hook is useful for conducting measurements with the sample suspended beneath the balance, such
as in specific gravity measurement.

Attachment method

Attach the below-balance weighing fitting by screwing the supplied
screws into the screw holes for the transportation screws on the
bottom of the balance (2 places), as shown in the diagram on the
right, until the screws cannot be tightened anymore.

Note:

Be careful to ensure that no undue force is applied to the fitting
when putting down the balance while the fitting is attached.
Otherwise, the balance may not operate correctly. In particular, do
not put down the balance in a location where there is no hole for
below-balance weighing.
