Go out end to be connected with another input of the comparator, the output end of the comparator electrically connects with corresponding indicator lamp.Weight
Amount collector timing acquiring weight data is sent to single-chip microcomputer, single-chip microcomputer passes through the first output end by the weight data that this is received
Comparator is sent to, the weight data that the last time receives is sent to comparator by the second output end, the comparator incite somebody to action this
The secondary weight data received is compared with the weight data that the last time receives, when this receives weight data less than or equal to upper
During the weight data once received, the comparator exports high level, and the indicator lamp is bright.
In another embodiment, the acquisition interval of the Weight acquisition device is 10-60s.It can adjust as needed
The acquisition interval of Weight acquisition device.
In another embodiment, the height of the filtrate collection vessel rest area in the lower support plate can be adjusted independently
Section.The height of filtrate collection vessel rest area can be adjusted according to the specification of each funnel.
In another embodiment, it is additionally provided with glass rod putting hole beside each funnel putting hole.Glass rod is placed
Hole can place glass rod, facilitate experimenter to be stirred.
In another embodiment, buzzer, the buzzer and all comparators electricity are additionally provided with the support
Connection.Buzzer can prompt experimenter so that experimenter without staying in filtering area always by sight.
