Indicates that the addition function is enabled for accepting an additional load. ○ Indication of stable balance (If this light is off, the balance is unstable.
3 Installation of the Balance 1. Attach the pan base and pan. Attach the pan base and pan to the main unit as shown in the figure. 2. Level the Balance. Turn the adjustable feet so that the air bubble in the level gauge is within the circle. 3. Connect the AC adapter. Connect the AC adapter to the balance. (Refer to “Section 21, Operate on Batteries” on page 81 if the Batteries option is employed.
4 Basic Operation 4.1 Power On/Off Press the On/Off key to turn the power on and off. The * sign is displayed when the balance is powered by the AC adapter and is in standby mode. The balance will start in the mode it was in when last turned off. For example, if you turn off the balance in the parts counting mode, it will start in that mode when it is next turned on. (Refer to “Section 5.2: Description of Functions 1” on page 16 for details of the weighing modes.) 4.
This operation is called “Tare” and “Net” is displayed while the weight of the pan is being set. After the weight of the pan has been set, if a sample is placed in the container the balance will display the weight (net weight). * When a tare range is set, the weighing capacity is reduced accordingly. Weighing capacity = original weighing capacity – pan weight Even after the weight of the pan has been set and the display is set to “0,” the value indicated by the bar graph includes the pan weight. 4.

7 Weighing and Measurement Modes You can select from one of five weighing modes: weighing machine, parts counting, percentage weighing, unit converting, and gravimeter. In addition, the balance is equipped with addition and limit functions as additional functions. All the weighing modes except gravimeter support the additional functions (the addition function and the limit function) depending on the display unit. 7.
8 Parts Counting When a specified number of samples are put on the balance, the balance divides the total weight of the samples by the number of samples to obtain the average sample weight. The balance stores the average sample weight based on the number of samples initially set. Additional samples, up to three times the initial number, can be added and the balance will automatically update the average sample weight. This mechanism allows accurate counting. * Select [1.
Repeating this operation will improve the resolution of parts counting for more accurate measurements. 5. Finish sampling. Press the Function key to finish updating the memory. The average sample weight is saved and the balance returns to measurement mode. 6. Counting the number of samples. After the average sample weight has been saved, the number of samples put on the balance will be displayed.
9 Percentage Weighing The weight of a reference sample is saved as 100%. When a sample is placed on the balance, the balance indicates the percentage of that sample with respect to the reference sample weight. A reference sample weight can be set by weighing an actual sample or entering a value. * Select [1. Set. 3] (Percentage Weighing) in Function 1. 9.
9.2 Set a reference weight by entering a value You can enter a reference weight in the balance, and then make the display indicate the weight percentage (%) of a sample with respect to the reference. 1. Displaying a reference sample weight. Make sure that the [%] sign is displayed and press and hold the Function key for a few seconds. (This operation may be performed with a container placed on the balance.) The display then blinks [P. SEt]. The previously saved reference sample weight blinks. 2.
10 Unit Converting The function to convert units multiplies the weight of a sample on the balance by the saved coefficient, and displays the result. * Select [1 1. Set . 4] (Unit Converting) in Function 1. Displaying the coefficient setting. Make sure that the [#] sign is displayed and press and hold the Function key for a few seconds. (This operation may be performed with a container placed on the balance.) The display then blinks [C. SEt]. The previously-saved reference sample weight blinks. 2.
For example, Displayed value (250.0000) = Coefficient (2.5) x Sample (100.0000 g) The increment of the minimum readability is automatically set to 1, 2, or 5 depending on the entered coefficient.
11 Gravimeter A sample’s specific gravity can be measured by using the balance as a gravimeter. Hang the sample from the balance using an optional hooking device. You may need to use a net, cage, string, or container to hang the sample from the balance. This manual describes the procedures for measuring the specific gravity of a solid by hanging it from the balance.
4. Measure the weight of the sample in the air. Put a sample in a cage or on a pan, and measure the weight of the sample in air. After the weight display is stable, press the Target key to enter the weight. Then, [] blinks in the display for a few seconds and the measured weight is displayed. When the weight is entered, [] is displayed in the lower left of the display. 5. Submerge only the hanging cage and set to “0”. Before the measurement in water, submerge only the cage and press the Zero/Tare key.
11.2 Entering water temperature or the specific gravity of the media This is for entering correction data for the liquid media to be used for the measurement. Enter water temperature if the media is water. Otherwise, enter the specific gravity value of the liquid. Use Function 1 [11.NEd. *] for selecting the media as follows: 1. Call the mode to enter a correction value.
11.3 Gravimeter measurement data output (1) Output before gravimeter measurement With the gravimeter function, the operation is with the “Pressing the Print key outputs the data” mode, regardless of the setting by [71. o.c. *]. (2) Output while specific gravity is displayed [12. dod] is used for selecting the output contents. The output method can also be selected by [13. A.o.].
12 Addition Function The addition function adds up the weights of samples put on the balance, allowing you to find the cumulative weight. Except for the gravimeter function, all other functions, i.e., weighing machine, parts counting, percentage weighing, and unit converting functions support the addition function. 12.1 Cumulate Function With the cumulate function, a cumulative weight can be obtained while samples are reloaded. Select [2. SEL 1 or 3] and [26. Ad. N 1] in Function 1. 1.
Obtain a total weight without reloading the balance Press the Zero/Tare key in step 3 without unloading the balance. This will reset the display to “0”. Put additional samples on, and press the Target key. Then, the weight is cumulated. 1. Put additional samples on when the display indicates “0”. 2. When [t - Err] is displayed when you press the Target key, it indicates that you put additional samples on twice, that you unloaded some samples, or that you pressed the key without adding samples. 3.
5. Display the cumulative weight. Pressing the Function key several times displays the cumulative weight with a [Σ] sign. 6. Clear the cumulative weight. Press the Zero/Tare key with the cumulative weight displayed. * The cumulative weight will be cleared when “zero adjustment” or “tare range” is performed while the weight of the sample on the balance is displayed. Press the Function key to return to the weight display mode. 1.
13 Limit Function The limit function judges a measured weight based on the limit values stored in the balance. The limit function can be set by selecting [2. SEL *] or [2] or [3] in Function 1. The limit judgment result will be indicated by the [] symbol. The number of judgment points can be set from one to four. 13.1 Setting the Limit Function Make the settings of the limit function in Function 1. While the limit function provides various setting items, carefully read Section 5.
When 3- or 4-points are set, triangles [] are displayed in four or five levels according to the judgment result. Judgment Result (3- or 4-point setting) Rank 5 (4-point setting) Fourth point ≤ Weight Rank 4 Third point ≤ Weight < Fourth point Rank 3 Second point ≤ Weight < Third point Rank 2 First point ≤ Weight < Second point Rank 1 Weight < First point The [<] sign stays on in the range where the [] sign is displayed depending on the number of points set. 13.4 Judge by Absolute Values 13.4.
When an upper limit is saved, that value is displayed for a while. Then the balance returns to measurement mode. 13.4.2 Set two limit values by entering values 1. Switch to the setting screen of limit values. Press the Target key for a few seconds. When [L. SEt] is displayed, release the key. The currently saved lower limit is displayed. 2. Enter a numerical value. Press and hold the Zero/Tare key. The digit furthest to the right blinks. 3. Select a number. Press the Zero/Tare key.

13.5 Judge by Deviation Values 13.5.1 Set two limit values by putting actual samples on the balance − Judge by Deviation Values − 1. Start limit value setting. Press and hold the Target key for a few seconds. When [r.SEt] is displayed, release the key. The current reference value blinks. 2. Enter a reference weight. Put a sample that provides a reference weight on the balance, and press the Function key. When a reference weight is saved, the value is displayed. The next item will then be displayed. 3.
13.5.2 Set two limit values by entering values − Judge by Deviation Values − 1. Start limit value setting. Press and hold the Target key for a few seconds. When [r.SEt] is displayed, release the key. The current reference value blinks. 2. Switch to the value input screen. Press the Zero/Tare key. A [] blinks in the right end of the display. 3. Enter a reference weight. Perform the same procedures as given in steps 3 and 4 in Section 13.4.
For example: When a judgment is made with a reference weight of 100.0000 g, a lower limit of 97.0000 g and an upper limit of 105.0000 g with a 2-point setting, enter the limit values as shown below: Reference Weight Lower Limit Upper Limit Absolute weight 100.0000 g 97.0000 g 105.0000 g Input Data 100.0000 g -3.0000 g 5.0000 g 5. Enter an upper limit value. Set an upper limit in the same way as in step 3 above. When you have entered the upper limit, press the Target key. 1.
(Example) To set a lower limit of 97.0000 g and an upper limit of 105.0000 g with respect to a reference weight of 100.0000 g, enter the limit values as shown below: Reference Weight Lower Limit Upper Limit Absolute weight 100.0000 g 97.0000 g 105.0000 g Judgment by absolute values 100.0000 g 97.0000 g 105.0000 g Judgment by deviation values 100.0000 g -3.0000 g 5.
13.6 Bar Graph for the 2-point Scale You can set two points for the limit function, and display a bar graph to indicate the result in a range specified by the two points. Except for the gravimeter function, all other functions, i.e., weighing machine, parts counting, percentage weighing, and unit converting functions can support this function. You can put actual samples on the balance or enter values to set upper and lower limits. You can also judge by absolute values or deviation values.
14 Calibration and Span Test for the Balance Span Adjustment An electronic balance, which is influenced by the acceleration of gravity, indicates different values depending on the location it is used. For this reason, you should calibrate your balance every time you relocate it. You should also calibrate it after a long time of no use or when it does not indicate correct values. To calibrate a balance is called span adjustment, which is required for highly accurate measurements.
3. When [on F.S.] is displayed, put a weight on the pan. The balance starts adjusting the weighing capacity. The display indicates [buSY]→[End] in sequence. When span adjustment is completed, the balance goes back to the normal display. 14.3 Span Test with Built-In Weights 1. Press the Cal key. [t. int] is displayed. 2. When [PuSH C] is displayed, press the Cal key again. The built-in weight unit starts to operate, and the balance will automatically start span test.
14.5 Calibration of Built-In Weights This function allows you to calibrate the built-in weight using external weights. You should perform this operation when the balance has been subjected to a strong impact.
(Pressing any key while an error message is displayed returns the display to measurement mode.) * When one of these messages is displayed, calibration will not be performed. Check that you are using a proper weight, and start span adjustment or a span test again. If span adjustment with a proper weight results in the same error message, contact our Marketing Division or Technical Service Division. 4.
14.6 Entry of Weight Error By entering the weight error of an external reference weight to be used in span adjustment or span test, a more accurate calibration can be performed. Enter the weight error obtained from the following equation: (Weight errors are entered in the unit of mg.) Weight Error = Actual Weight - Nominal Value Example: For a 100 g weight, a weight error may be = 100.00012 - 100 = 0.00012 = +0.12 mg 1. Select [2. o.NP. 1] in Function 2. 2. Display the weight error.
☆ Hints ☆ If more than one weight is used in combination, enter the total error of the weights to be used. The range of the weight error should be within ±100.00 mg. If any value outside the range is entered, it will result in the display of [r - Err]. When [r - Err] is displayed, press any key to return the display to Step 2. 14.
