44 BM seriesStability band width ( 5t-b )This item controls the width to regard a mass value as a stable value. When the fluctuation persecond is less than the parameter, the balance displays the stabilization indicator and outputs orstores the data. The parameter influences the "Auto print mode".5t-b 0 This parameter is used for sensitive response of the stabilization indicator. Used forexact weighing.5t-b 2 This parameter ignores slight fluctuations of a mass value. Used to prevent a massvalue from drifting due to vibration or drafts.Display Hold Function ( ploc )This function is used to measure the volume dispensed from the pipette.When specifying "Display lock function is used" (ploc on) in the function table, dispensing liquidinto the weighing bottle from the pipette and getting a stable weighing value, the balancecalculates an average value and displays the result (a fixed value).When using this function for the measurement of a small volume, the influence of waterevaporation can be reduced.Caution Even if using the weighing bottle (evaporator trap) to reduce the waterevaporation, at least 0.05 mg (0.05 ) evaporation will occur.When canceling this function, press the RE-ZERO key.Calculating Fixed resultZero tracking ( trc )This function tracks zero point drift caused by changes in the environment and stabilizes the zeropoint. When the weighing data is only a few digits, turn the function off for accurate weighing.trc 0 The tracking function is not used. Used for weighing a very light sample.trc 1 The normal tracking function is used.trc 2 The strong tracking function is used.trc 3 The very strong tracking function is used. Used for stable zero display.Display refresh rate ( 5pd )The periodic time to refresh the display. This parameter influences "Baud rate", "Data outputpause" and the data output rate of "Stream mode".Decimal point ( pnt )The decimal point format can be selected.Auto display-ON ( p-on )When the AC adapter is plugged in, the display is automatically turned on without the ON:OFF keyoperation, to display the weighing mode. Used when the balance is built into an automated system.One hour warm up is necessary for accurate weighing.In calculation. It blinks. Processing indicatorStable mark
