1. COMPONENTS AND THEIR NAMES Components Included with every balance are one of the following items. • Balance body • AC adapter (option) • protection cover • Pan • Pan supporter • Instruction manual • Inspection certificate • Breeze guard (Only type, BL220H (L) and BL320H (L)).
CAUTION • Use only the AC adapter that supplys the output of 12VDC or the AC adapter provided by the distributor who is authorized by Shimadzu Corporation. CAUTION • Check the power supply voltage. CAUTION • Check that the supplied power voltage satisfies the displayed value on the AC adaptor.
Place the pan supporter on the pan shaft and then the pan on the pan supporter. Plug the AC adapter into the outlet. The balance shows after self-checking. Press the POWER/BRK key. displays light for one minute. Then the display automatically shows "zero" and the balance enters measurement ready state.
4. CAUTION NOTES • put water, metal pin or any thing in the balance; Do not..• open the balance case; • leave anything exceeding the weighing capacity on the pan; • expose the balance to anything magnetized; • connect anything other than the specified equipment to the connector on the rear side of the balance;...
6. MENU SELECTION This balance is designed to permit selection of the measuring conditions to compensate for vibration and other conditions present at the installation site. This feather permits greater weighing efficiency and accuracy, and is referred to as “Menu Selection”. Also in BL series, setting the balance to “...

• If the measurement is done at severe measurement environment and the stability of the display is not so good, set the balance to “ ” (high-stability mode). • When the high-speed sample pouring mode is executed, or the small mount of sample pouring is done, set the balance to “...
6.1 Menu selection when “ ” is selected Pressing the TARE key when the “ ” is displayed at 1st hierarchy menu enters 2nd hierarchy menu. In this menu, ON/OFF of zero tracking, setting the stability detection band, registration/cancel of unit, ON/OFF of auto print, and ON/OFF of analog display are made. Key operation and each setting are made as follows.

6.2 Menu display when is selected Pressing the TARE key when the “ ” is displayed at 1st hierarchy menu enters 2nd hierarchy menu. In this menu, the input/output format can be set. (→) : Press the TARE key. (←) : Press the POWER/BRK key.
7. SENSITIVITY CALIBRATION The electronic balance measures mass by electronicity compensating for terrestrial gravitation. Since gravitation varies slightly in different regions, span calibration (sensitivity calibration) is required when the balance is installed. Temperature also effects balance accuracy, and calibration must be performed whenever a significant change occurs. It is good practice to calibrate the balance whenever the balance is moved or unexpected shock is applied to the balance such that an article drops on the pan.

7.2 Sensitivity Calibration Perform the sensitivity calibration as follows. Step Warm up the balance well. Refer to “3. WARM-UP”. Check leveling. Unload the sample on the pan and press TARE key to zero the display. Following the menu selection, press the CAL/MENU key to display “...
8. REGISTRATION, CANCEL, AND CHANGE OF UNIT Step for registration (1) Press the CAL/MENU key and select the display. (Press the TARE key.) Press the CAL/MENU key and select the display. (Press the TARE key.) The registrable unit is displayed by every pressing the CAL/MENU key.
9. % SETTING This balance serves percent (%) display by setting the reference sample to 100%. Step Register the % unit. (Refer to “8. Registration, cancel, and change of unit”. When % unit has been already registered, it is not necessary to register again. Place the tare on the pan and press the TARE key.
10. PCS (No. of pieces) SETTING This balance can perform No. of pieces measurement (unit PCS). No. of standard pieces is 10 pcs, 20 pcs, 50 pcs, or 100 pcs. When the No. of pieces is increased, the accuracy is improved. Step Register the PCS unit following the unit registration.
11. PERFORMANCE CHECKS Conduct performance checks in a room where the temperature does not change suddenly. These checks are used to determine if the balance conforms to specifications, and should be performed with the greatest care. • Warm up the balance well. Preparation •...
Eccentric error Prepare a sample which weights approximately 1/4 of the balance capacity and move it on the pan in the order as shown right. Record the results of X1 to X5 in this order. If the difference (eccentric error) between readings at the center position and the off center positions is as follows: BL320H (L), 3200H (L),:7counts BL H series: 4 counts...
13. TROUBLESHOOTING For countermeasures having an asterisk, contact the nearest Shimadzu sales or service center. When What trouble Cause -> Countermeasure • Nothing is displayed by connecting • The AC adapter is disconnected. Before • The electrical board is turned OFF.
