A&D Weighing BM-20 - Manual (Page 46)

44 BM series
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 liquid
into the weighing bottle from the pipette and getting a stable weighing value, the balance
calculates an average value and displays the result (a fixed value).
When using this function for the measurement of a small volume, the influence of water
evaporation can be reduced.
Caution Even if using the weighing bottle (evaporator trap) to reduce the water
evaporation, at least 0.05 mg (0.05 ) evaporation will occur .
When canceling this function, press the CAL key.

Fixed result
Zero tracking ( trc )
This function tracks zero point drift caused by changes in the environment and stabilizes the zero
point. 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 output
pause" 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 key
operation, to display the weighing mode. Used when the balance is built into an automated system.
One hour warm up is necessary for accurate weighing.
