4. STRUCTURE INSTRUCTION
4.1
±
15V Power Supply
Composed by three-terminal integrated stabilized modules,
±
15V power supply with the simple connection, high
stability and reliability are available as well as over-heat and over-load protections in the integrated stabilized
electric circuit.
4.2 +5.00V Nominal Power Supply
From the +5.00V nominal power supply, the 0~5V voltage output which is adjusted by its set potentiometer can be
used for controlling MFCs. Because of the soft-start circuit, the voltage will rises gradually from 0 to +5V for
avoiding the overshoot of MFC responding. The time of soft-start will cost 20 seconds approximately.
4.3 Displayer
3 and 1/2 numbers panel can display the readout from MFC (The maximum value: 1800). Flow rate can be
displayed by “SCCM”, “SLM” or “%FS”. Normally, the default flow range and unit of Flow Displayer will be set
to the user want to. If the user cannot give MFC flow specifications, the default will be set as %FS. The SLM and
SCCM LBD in the frontal panel will indicate the flow unit. Two LBD off means that flow unit is %FS. The radix
point, unit of every channel could be adjusted respectively.
