2. BASIC INFORMATION 2.1. Intended use The purchased balanced serves to determine the weighing value of loads in laboratory environment. It is intended for application as a non-automatic weighing instrument only, i.e. the material to be weighed is manually and carefully placed in the centre of the weighing pan. Weighing result should be read only after stable reading has been obtained. 2.2. Inappropriate use Do not use the balance as a dynamic weighing instrument.
PAGE 11
2.4. Monitoring the metrological parameters of the instrument Metrological characteristics of the balance require periodical inspection to be carried out by its user. Inspection frequency is dependent on ambient conditions in which the balance is used, types of performed processes and accepted quality management system in organisation. 2.5.

10. WEIGHING 10.1. Required weighing procedures In order to ensure long lasting use of a balance and reliable measurement of weighed loads, follow below procedures:  Start the balance with no load on the weighing pan (permissible value of load on the weighing pan on balance start is ±10% of its maximal capacity).
PAGE 29
Before the start of weighing process or in case of drastic change of ambient conditions at a workstation (e.g. ambient temperature change at a workstation more than 3°C) the balance requires adjusting. The procedure of balance adjustment is described further in this user manual.
PAGE 30
10.2. Zeroing In order to zero mass indication press button. The mass indication on the display should equal zero, and precise zero should appear. and stability marker Zeroing process is tantamount to determining new zero point recognised by the balance as precise zero. Zeroing is possible only in stable status of display indication.

Manual tare determination Procedure: • While in optional mode press quick access button F, to which the option is assigned in settings (description of the setting further in this user manual, point ), • which opens a window, button, • use the arrow buttons to enter tare value and press • the balance returns to weighing mode, and the display indicates entered tare value with minus „–" sign.
PAGE 32
Deleting tare button on the Entered tare value can be deleted by pressing balance’s overlay or by entering tare value of 0.000g (see description above). 10.4. Settings for mode The software allows the set-up of operating parameters (filters, value release and autozero option, deleting the last digit and other settings) separately for each working mode.
PAGE 33
should be set to slow or very slow (parameter value P.2.2.1.1 to SLOW or V. SLOW). The effectiveness of the filter is different for the weighing range. The filter works slower when “approaching” the weighed mass, it works more intensively when the weighed mass is placed within the set range of the filter (parameter filter range is accessible only from the service menu – the user does not have an access to it). Depending on the adjusted filter, the weighing time will be shorter (V.
PAGE 34
1.1.3 Autozero function In order to ensure balance’s precise mass indication, autozero (Auto) software parameter has been introduced. The application of this function is automatic control and correction of zero indication. When the function is enabled, it compares balance indications at declared time interval e.g. 1s, on condition that weighing pan is unloaded and display indication is close to zero. If results vary less than declared AUTOZERO range e.g.

PAGE 49
13. BALANCE ADJUSTMENT In order to ensure the highest weighing 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. Adjustment should be carried out: Before the beginning of weighing procedure, If long breaks between following measuring series occur, If temperature inside the balance changes more than: 3°C.
PAGE 50
13.1. Internal adjustment Adjustment process can be initiated automatically and manually. Manual means of activating adjustment procedure is achieved by pressing . System of automatic adjustment will carry out the process fully automatically and will inform the user on successive process stages. Cycle of automatic adjustment process: - Balance software detects the necessity of carrying out adjustment and signals it by displaying a thermometer pictogram and at the top of the display.
PAGE 51
Automatic adjustment process takes place in three different areas: • Adjustment on plugging the balance to mains – verified balances. • Adjustment triggered by temperature change inside the balance. The balance is equipped with very precise system for monitoring temperature. At each adjustment process, the temperature is saved in the system. The next adjustment is automatically initiated if temperature changes more than 3°C from the last saved temperature. • Adjustment triggered by elapsing time.
