Operating Instruction - Precision Balances PS series - MRC

9.3. Autozero functionIn order to ensure precise indication of balance, „AUTOZERO” function wasintroduced. The application of this function is automatic control and correctionof zero indication of balance.When function is active comparison of results takes place at declared timeintervals e.g. every 1 s, only when the pan is unloaded and results are close tozero.If results vary by value smaller than declared AUTOZERO range e.g. onedivision, balance will zero automatically and stable result marker– andzero indication – will be displayed.When AUTOZERO function is on each result starts from precise zero. Howeverthere are some cases where this function can be disturbance atmeasurements. Such instance is very slow placing of load on the pan (e.g. loadpouring) in such case correction system of zero indication can also correctindication of real mass of load.Procedure:AUTOZEROAUTOZEROOFF – autozero offOn - autozero on.Return to weighing(see - 7.1.2. – return to weighing).26
