Fig. 8. Balance submenu – selection buttons 7. WEIGHING Basic working conditions for obtaining reliable measurement results: - Stable and constant temperature in a weighing room, - Stable foundation of a balance, - Selecting adequate balance settings adjusted to ambient conditions at a workstation. Before start of weighing process or in case of essential change of ambient conditions at a workstation (e.g. ambient temperature change at a workstation more than 1°C/h) the balance requires adjusting.
Press Units key to set a measuring unit. Place weighed object on balance’s weighing pan and read the result only on stabilization of the measurement. If the measuring unit is not displayed on pressing the Units key, then go to the corresponding submenu and check the accessibility attribute of the measuring unit. Mass indication of a load placed on balance’s weighing pan can be zeroed for multiple times. Pay attention not to exceed maximal capacity of a balance by applying multiple zeroing function.
Independently on pipette calibration option, the process requires assembling a dedicated adapter for pipette calibration featuring an evaporation trap (see user manual section: UNPACKING AND INSTALLATION”). The purpose of the evaporation trap is to minimize measurement errors occurring on liquid evaporation while its weighing. Before carrying out the pipette calibration process, pour distilled water to the 2/3 of the evaporation trap height.
7.2. User log in The users of a balance XA/2X series can have their specific access code to the balance’s menu. The password system is determined by balance’s administrator, i.e. a user of the higher order in relation to the other balance users. The access password can comprise up to 6 digits. Balance software enables determining: • • A single Administrator, who has access to all balance settings and software functions, including changing the password of the administrator and other users.
Fig. 9-1. Password protection – menu content - Administrator the field for inserting administrator’s password. Balance administrator has access to all balance functions and settings. - User the field for inserting user’s password. Balance user has access to the functions and settings which attribute is set to NO (i.e. no password protection). - Startup if the option is set to YES, then on balance startup the software requires entering a password (of the administrator or user).
Inserting Administrator’s password Enter a password for the balance administrator (a sequence of 6 digits) and for the user. Balance administrator has full access to balance menu. The user access is limited to the one described in previous point (balance menu, startup, adjustment, etc. options can be attributed YES/NO).
8. ADJUSTMENT In order to ensure the highest measuring accuracy, it is recommended to periodically introduce to balance memory a corrective factor of indications in relation to a mass standard – i.e. balance adjustment.
The time delay enables the user to take the weighed load of the weighing pan, if a weighing process is in progress. Pressing T/O key causes temporary delay of the adjustment process initiation. Automatic adjustment settings Fig. 12.

to 4 or 5). The effectiveness of filter operation differs in relation to the measuring range. The filter operates with lower accuracy while the mass indication is quickly increasing after placing a load on the weighing pan. Filter accuracy is increased when weighed mass is within filter’s set operation range (parameter: filter operation range is available only in balance’s service menu, and it is inaccessible for the user). 11.2.
11.6. Negative The function aids previewing mass value and other indications on the display. Depending on user needs it is possible to enable or disable the function. 11.7. Air buoyancy correction The air buoyancy correction enables correcting errors occurring while mass measuring processes, i.e.: 1. Determining mass of a sample which density considerably differs from the density of a mass standard used for adjusting the balance.
11.7.1. Means of operation The software enables two means of using the air buoyancy correction. 1. By inserting to balance memory known value of air density and known density value of weighed sample. After inserting these values the application automatically calculates correction factor for measured mass and after re-calculation of sample mass displays correct mass value. In order to avoid any errors, the re-calculated mass is proceeded by and exclamation mark (!) on the display and on a printout. 2.
Set value of parameter P4 07 Air buoyancy correction to 1: yes After returning to weighing mode with procedure of saving changes the display indicates pictogram (!). From now on the displayed mass is corrected in relation to buoyed air and density of weighed sample. Fig. 28-3. Balance menu – enabling air buoyancy correction In order to correct the mass of weighed object using air buoyancy correction mode, remember to apply current density values of the air and the weighed sample. 11.7.3.
Determining air buoyancy correction is also carried out using a dedicated set of 2 pieces of mass standards. One of the mass standards is made of stainless steel, and the other of aluminum. Each of the mass standards has specifically determined mass and density. Determining procedure: 1. Enter the density mode. 2. After entering the mode select appropriate procedure 3. On entering mode settings, set required data (mass and density) in the corresponding fields Fig. 28-6.
Fig. 28-8. Air density – declaring values of mass and density 4. 5. After inserting all required data start the determining procedure – move the marker to the START field and press F key Load the weighing with the stainless steel mass standard and on stabilization of measurement result press ENTER key Fig. 28-9. Air buoyancy correction – determining mass of a stainless steel mass standard 6. Mass of the stainless steel standard is saved in balance’s memory.

Air buoyancy correction – the air density correcting coefficient At this stage the user can: − Restart the procedure from the beginning (by pressing Units key) − Return to weighing without saving changes on air density determination (press MODE key and select mode WEIGHING) − Accept calculated density value. Fig. 28-12. Air buoyancy correction – Message window 8. The display indicates the calculated values – the balance is ready for operation with the determined air density coefficient.
11.8. Operating conditions This parameter enables two settings: stable or unstable. Setting the parameter to stable causes much faster operation of the balance, i.e. the weighing time is shorter than compared to setting: unstable. This parameter refers to operating and ambient conditions at a workstation. If the conditions are unstable, then it is recommended to set the parameter to unstable. The default setting of the parameter is: stable.

COOPERATION WITH A PRINTER OR A COMPUTER Each pressing of < PRINT > key causes sending to a connected printer or computer a signal corresponding to current mass indication (display status) with enabled measuring unit. The default baud rate setting of a balance is 9600 bit/sec. If a peripheral device (a printer or a computer) requires other baud rate settings then it needs to be changed in balance parameter settings. 19.1. Cross-section through connecting cables Fig. 64.

COOPERATION WITH A CITIZEN LABEL PRINTER Ensuring correct balance cooperation with a label printer requires acting as specified in the following description.
− − Text string for start and stop of a selected printout After each measurement result the printer should print 3 labels Principles for designing a printout: − Insert into text strings data to be included in a printout – group of parameters P6 Printouts; parameters: Text 01 ÷ Text 80. When designing a printout template use variables for controlling label printout (table 1) and variables for sending specific data from a balance.
− On adding data on a non-standard printout set other printout parameters, such as: Printout no. –1 Printout no. 1 start – 1 Printout no. 1 stop – 10 Fig. 67. Declaring printout content − On setting printout parameters go back to the weighing mode with procedure of saving carried out changes. Next, connect a label printer to balance’s communication interface using a dedicated cable (see figure on cross-section of a connecting cable given in this user manual).
