BSM Electronic balance could ensure the accuracy and trustiness of the weighing result with the splendid performance: Could eliminate the influence of bad circumstance like vibration and airflow effectively With reliable and nice repeatability With firm structure BSM Series Electronic balance：fast weighing, simple operation, to predigest and accelerate the normal weighing process greatly.
Safety Precautions Safety Instructions Please read these operating instructions carefully before using your balance to prevent damage to the equipment. △ Do not use this equipment in hazardous areas/locations. △ The balance housing may be opened only by authorized technicians who have been properly trained at the factory. △ Make sure you disconnect the balance from power before connecting or disconnecting peripheral devices to or from the balance.
Getting Started Storage and Shipping Conditions Do not expose the balance to extreme temperatures, moisture, shocks, blows or vibration. Unpacking the Balance After unpacking the equipment, please check it immediately for any external damage. If damage is evident, refer to the instructions under “Safety Inspection" in the chapter entitled “Care and Maintenance." Save the box and all parts of the packaging for any future transport.
Getting Started Installation Place components inside the chamber in the following order: Shield ring Pan support Weighing pan Place components inside the chamber in the following order: Weighing pan 4
Getting Started Connecting the Balance to AC Power/Safety Precautions Use only original BSM power adapter. Insert the right-angle plug from the AC adapter into the jack on the balance. The AC adapter rated to Class Ⅱ can be plugged into any wall outlet without additional safety precautions. Antitheft Locking Device You can use the security device on the back of the balance to avoid the steal behavior. You can use chain or lock to insert into the security device, and connect with a fix point.
Getting Started Leveling the Balance Purpose: To compensate for unevenness at the place of installation Only the 2 front feet are adjusted to level the balance whose weighing capacity is below 2kg. Turn the 2 front feet as shown in the diagram until the air bubble is centered within the circle of the level indicator. Adjust the Leveling feet until the air bubble is centered within the circle on the level indicator. > In most cases this will require several adjustment steps.

Operation Basic weighing function Purpose The basic weighing function can be used alone or in combination with an application program(counting, weighing in percent, etc.). Features Taring the balance Printing weights Before using the balance at the first time, calibrate and adjust it at the place of use; For details, see “Calibration and Adjustment” in the next chapter. The temperature range (℃) indicated on the verification label may not be exceeded during operation. Working with BSM-120.4,BSM-220.
Operation Example Simple Weighing Settings: Application program: . . (default setting) Step Key(or instruction) 1. Switch on the balance. ［ ］ Self-test is performed, followed by automatic initial tare function. 2. Place container on the balance (in this example,52 g). 3. Tare the balance. Display/Data output + . + ［TARE］ 4. Place sample in container on balance(in this example, 150.2 g). + + 9 g . . g g .
Operation Calibration and Adjustment Purpose Calibration is the determination of the difference between the weight result and the true weight(mass) of a sample. Calibration does not entail making any changes within the balance. Adjustment is the correction if any difference between the measured value display and the true weight(mass) of the sample, or the reduction of the difference to allowable level within the maximum permissible error limits.
Operation External Calibration The weight required for calibration/adjustment is defined in the factory settings (see “Specifications”). Step Key (or instruction) 1. Zero the balance 2. Start calibration The balance will show “PLEASE WAIT”, after stable it will Display the prompted calibration weight (In this sample, 200g) Display/Data output . ［TARE］ PLEASE WAIT [CAL] 4. Apply the prompted calibration g + . g CAL + . g CAL weight 5.
Application Programs Application Programs Function Keys [F]key: Start application program/store component Toggle between units press and hold for 2 seconds change reference quantity (counting), reference percentage (weighing in percent) or number of measurements (animal weighing) [CF] key: End application program; delete Calculated values are alternately indicated with the following symbols: Percent = % Piece count (Counting) = pcs Computed value = o, 12
Counting Menu code: . . Application Programs Display symbol: pcs Purpose With the Counting program you can determine the number of parts that each have approximately equal weight. To do this, a known number of parts (the reference sample quantity) is weighed first, and the individual piece weight (reference weight) is calculated from this result. Thus the number of parts subsequently placed on the balance can be determined from their weight.
Example Application Programs Counting parts of equal weight Settings: Menu: Counting program (menu code: . . ) Reference pieces：20 pieces(code . . ) Step Key (or instruction) 1.switch on the balance ［ ］ 2. Tare the balance. ［TARE］ 3. Display reference pieces ［F］>2 sec Display/Data output . g (briefly) (in this sample is 20 pieces) 4. Add reference sample quantity to container(in this example: 20 pcs,66g). 5. Print piece count, if desired. ［F］ 6. Add uncounted parts as desired.
Application Programs Weighing in Percent: ( Menu code: . . ) Purpose This application program allows you to obtain weight readouts in percent which are in proportion to a reference weight. Features Storage parameter (rounding-off factor) for storing the reference weight to calculate the percentage can be configured. Changing the reference sample percentage in the menu: reference the chapter Balance setting.
Application Programs Example: Determining residual weight in percent Settings: Menu: Weighing in percent program (menu code: . . ), Reference percentage: ref 100% (Code: . . ) Step Key (or instruction) 1.Switch on balance. ［ ］ 2.

Optional: print percentage. + ［F］ 6. Place the residual weight + （in this example is 322.
Application Programs Density Determination: ( Menu code: . . ) Purpose This application program lets you determine the density of solid substance using the buoyancy method. You can have results displayed with one decimal place, or no decimal places: see “Configuration.” Note: the sample holder and suspension wire used in the example below are not included with the balance/scale. Features Set the display accuracy in the Setup menu: see “Configuration.

Application Programs Animal Weighing/Averaging(Menu code: . . ) Purpose weights of unstable samples (e.g., live animals) or to determine weights under unstable ambient conditions. With this program, the balance calculates the weight as the average of a defined number of individual weighing operations (also referred to as “subweighing operations"). Features Arithmetic average displayed as a result in the pre-set weight unit (identified by triangle signal ).
Application Programs Example Determining animal weight with automatic start of 10 subweighing operations Settings: Menu: Animal weighing program (menu code: . . ), Step Key (or instruction) 1.

Care and Maintenance Repairs Repair work must be performed by trained service technicians. Any attempt by untrained persons to perform repairs may lead to hazards for the user. Cleaning Unplug the AC adapter from the wall outlet (mains supply). If you have an interface cable connected to the balance port, unplug it from the port. Make sure that no liquid or other foreign objects or dust (powder) enters the balance housing. Do not use any aggressive cleaning agents (solvents or similar agents).
